Why is the mtime on /etc/db/quota.db set to zero (Dec 31, 1969 EST) ? Is this where the user quotas and disk consumption are stored? This is on a F630 running 4.2a Steve Losen scl(a)virginia.edu phone: 804-924-0640 University of Virginia ITC Unix Support

If RAID scrub finds a block it can't read, it reads the corresponding blocks on all the other drives and reconstructs the missing data. Then it re-writes the unreadable block, which remaps the block to a new location. I believe the remapping occurs automatically, because we set an auto-remap flag on the drives, but this may vary from drive to drive. This doesn't require a spare disk. > I guess it still could help with localized media errors, but I've > never seen any reaction to media errors other than a whole disk > failing out. If a WRITE fails, then we do drop the whole disk out. This is because, with auto-reremap, a WRITE should never, ever fail. If it does, there's something seriously wrong. A read failure during normal operation is handled as described above with RAID scrubbing. The block is rebuilt and rewritten so that the drive remaps it. We added RAID scrub because single block failures do occur, and they are nasty. If you've got an undetected bad block, and then a different disk fails entirely, then the stripe with the bad block will be impossible to reconstruct, because it has two missing blocks. In this case we zero both blocks and require the user to run WACK to fix whatever damage that causes. That generally works, unless the lost block is really important, but it's much, much better to find and fix the bad block right away, which is what the scrubbing does. It actually took a year or two before we started seeing this problem in our install base. We figure that it just takes a while before a system sits long enough to have files that never get read, and then for a failure to occur in such a file. Dave

Does anyone know of any good tools to snoop NFS traffic? I'm looking for something better than snoop or tcpdump that caches lookups and decodes file names, etc. - Dan

filesystem and RAID questions
by Daniel Quinlan 07 Dec '97

07 Dec '97

A few questions maybe someone could answer: - Why does a NetApp scrub the disk when it is in degraded mode? - What is the chunk size in NetApp RAID (using the term "chunk" to mean the amount of data written on each disk in each stripe)? - Is the WAFL block size still 4k? I seem to remember that it had grown, but all of the online documentation says 4k. Thanks. Dan

Re: "netapp" - command-line NetApp remote monitoring

just fyi, some mib names can be a bit misleading. for example CpuBusyTimePercent is not an instantaneous value of cpu utilization, but rather the percent time the filer has been doing useful work since the last reboot. read the mib carefully. -ashley

"netapp" - command-line NetApp remote monitoring
by Daniel Quinlan 06 Dec '97

06 Dec '97

This Perl 5 script (I can it "netapp") can be used to remotely monitor a Network Appliance via SNMP. To use it, you need a working version of "snmpwalk" and "snmpget" from the UCD snmp tools distribution in addition to version 1.1 of the NetApp MIB. I might switch it over to using the Perl5 SNMP module eventually. You'll possibly have to change some paths and parsing depending on how different your SNMP tools installation is from ours. I wrote this to allow non-privileged users to get information from the toaster without logging in or running rsh. These are the basic commands supported: partial sysstat -> "netapp -sysstat filer" or "netapp -sysstat=60 filer" df -> "netapp -df filer" df -i -> "netapp -if filer" also -> "netapp -df -if filer" It's pretty intelligent about loading the network too. An earlier version of this script only used snmpwalk, which produces a lot of back-and-forth chatter, even if you walk a very small portion of the SNMP tree. Example output: $ netapp -sysstat myf330 CPU NFS Net kB/s in out 35% 411 675 915 16% 164 230 153 $ netapp -df myf630 Filesystem kbytes used avail capacity Mounted on / 78277988 54447172 23830816 70% / /.snapshot 8697552 19281448 -10583896 222% /.snapshot $ netapp -if myf630 Filesystem iused ifree %iused Mounted on / 694555 2174415 24% / I hope this is useful to someone...

Quad Ethernet Card Support
by John F. Kane 02 Dec '97

02 Dec '97

The Data ONTAP Software Release 4.3R3 field alert and "4.3 Configuration Guild" have left me with the following questions: 1.) Is the quad-port 10/100Base-T card supported on the F330? 2.) If so, can I have three dual-attached FDDI cards active at the same time as the quad-port 10/100Base-T card on the same F330? This is necessary to support our backbone migration from FDDI to ATM. 3.) Is the quad-port 10/100Base-T card supported on the F230? 4.) What support for quad-port 10/100Base-T cards does ONTAP 4.3 provide? Does any previous release support the card? Any help is appreciated. -- John F. Kane Lead Staff, G052 Joint Analysis Center, EUCOM The MITRE Corporation

"quota resize" wish
by Steve Losen 01 Dec '97

01 Dec '97

We're running 4.2a on a F630. It would be nice if "quota resize" would work when you add a new entry to the /etc/quotas file when you have a default quota. In other words, if /etc/quotas has a default quota entry and a user has no entry in /etc/quotas, he gets the default quota. The netapp keeps track of his disk consumption and even "quota report" lists the user. But if I add a new entry to /etc/quotas to give this user a new quota, "quota resize" ignores it. I don't think it would be very hard for "quota resize" to work in this case. Would it? I can see a problem if the netapp does not keep track of the disk consumption of users who have no quota. Then adding a new entry to /etc/quotas would require the netapp to compute the user's disk usage on the fly. This would be about as expensive as a complete "quota on". But when you have a default quota, every user has a quota, so this isn't a problem. At the very least, I think "quota resize" should work for every user whose disk consumption is currently limited by a quota, even those with the default quota. Likewise, it would be nice to be able to delete a line from the file and have the user revert to the default quota after a "quota resize". (The latter may already work; I haven't tested it.)

auto-mounting CIFS shares at boot time?
by rasmus＠bellglobal.com 26 Nov '97

26 Nov '97

Please take pity on a poor Unix hack who has gotten a bunch of NT servers shoved onto his network. I am trying to get these boxes to automatically mount a CIFS share when they boot. So far I have only been able to get the share to come up when I log a user in. When the user logs out the share disappears. Not exactly a good thing when you have a web server service running in the background trying to serve up pages directly from this Netapp cifs share. My kingdom for /etc/vfstab for NT! Any tips would be appreciated. -Rasmus

RE: auto-mounting CIFS shares at boot time?
by Matt Lewin 25 Nov '97

25 Nov '97

Guy is right about the dialog box popping up if NT does not already have your password cached. You would need to have already logged in at that point anyway. There are two ways to accomplish what you want (that I know of): 1) If your web server is running as a service, you can typically configure it to log in as a user at bootup time. To do this, open the "Services" control panel and double-click on your web server service. You should then be presented with the capability of logging the service in under a particular account. This will allow the web server access to any resource the corresponding user account has access to. It has been awhile since I have used anything but IIS to do this sort of thing, so I don't remember if it is the only web server capable of using this facility. In fact, so many people had problems with this kind of thing before IIS 3.0, that they added support for mapping virtual directories using particular account names as of IIS 3.0. (Just look in Microsoft Internet Service Manager under WWW properties.) 2) If for some reason you can't (or don't want to) use the above mechanism, you can have NT automatically logon at boot up time. This is a less elegant, but completely effective way of accomplishing what you want. Obviously, there is a security risk in having a machine auto-logon, but if you set the screen saver to be password protected and to pop up in 1 minute, you should be relatively safe. Anyway, to do it, you need to edit the registry: Under the key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon, add a value named AutoAdminLogon. It must be of type REG_SZ with the value 1. (Yes, REG_DWORD really would have been better.) Then you need to have values for DefaultDomainName and DefaultUserName, according to where and who you want to log in. Then add another REG_SZ value named DefaultPassword containing the specified user's password. Then logout, and your machine should auto-login as the specified user. Some little tidbits about this technique: - It is obviously unsafe to have a clear text password in the registry, so you should make this user essentially powerless beyond his access to the web resources. - When the time comes that you don't want the machine to auto-login, hold down the shift key, and you will receive the normal bootup sequence. You can do this when you log the user out as well, so that you can log in to do whatever you want as a real user. - As of NT 4 SP something, you can't auto-login as Administrator (this is probably good anyway); it will work once, and then prompt you for the password again. Basically, the AutoAdminLogon variable is changed to 0 when the Administrator auto logs on. b/t/w, #2 is available somewhere on the MS knowledge base, I just don't remember the article off the top of my head. Hope this helps. -Matt On Tuesday, November 25, 1997 11:50 AM, Guy Harris [SMTP:guy@netapp.com] wrote: > > > and then worrying about drive N: being mapped to the right place by the > > > time the server starts up, feed it: > > > > > > \\FILERNAME\[WEBSHARE\]WWWROOT > > > > > > instead.

Unaccounted for disk space
by Brian Tao 25 Nov '97

25 Nov '97

I have four filers that are nearing production status, and the hardware and software configurations were frozen this morning. To start everything fresh, I zeroed all the disks and recreated the filesystem on all four filers, untarred the 4.2a distribution, restored the rc, serialnum, hosts and hosts.equiv files, downloaded the boot code to the drives, and rebooted. Once everyone was back online, I noticed there is a discrepancy between 'df' and 'du' outputs. 'df' says 40MB are used on two of the filers, and 4.5MB on the other two. 'du' from the admin host consistently reports about 4MB used. Where is that space on adm1-na2 and adm1-na3 going? Old snapshots (which I've all deleted)? The only files ever to have lived on these filesystems are the OS-related ones in /etc. All option settings are the same, maxfiles is set to the default, etc. || admin# df -k /na1 /na2 /na3 /na4 || Filesystem kbytes used avail capacity Mounted on || adm1-na1:/ 33007568 4520 33003048 1% /na1 || adm1-na2:/ 33007568 40192 32967376 1% /na2 || adm1-na3:/ 33007568 40184 32967384 1% /na3 || adm1-na4:/ 33007568 4408 33003160 1% /na4 || || admin# du -sk /na1 /na2 /na3 /na4 || 4048 /na1 || 4048 /na2 || 4048 /na3 || 4048 /na4 || admin# rsh adm1-na1 df || Filesystem kbytes used avail capacity Mounted on || / 33007568 4520 33003048 0% / || /.snapshot 0 0 0 ---% /.snapshot || || admin# rsh adm1-na2 df || Filesystem kbytes used avail capacity Mounted on || / 33007568 40192 32967376 0% / || /.snapshot 0 0 0 ---% /.snapshot || || admin# rsh adm1-na3 df || Filesystem kbytes used avail capacity Mounted on || / 33007568 40180 32967388 0% / || /.snapshot 0 0 0 ---% /.snapshot || || admin# rsh adm1-na4 df || Filesystem kbytes used avail capacity Mounted on || / 33007568 4404 33003164 0% / || /.snapshot 0 0 0 ---% /.snapshot || admin# rsh adm1-na1 snap list || working......... %/used %/total date name || .. || ---------- ---------- ------------ -------- || || admin# rsh adm1-na2 snap list || working.......... %/used %/total date name || . || ---------- ---------- ------------ -------- || || admin# rsh adm1-na3 snap list || working.......... %/used %/total date name || . || ---------- ---------- ------------ -------- || || admin# rsh adm1-na4 snap list || working........... %/used %/total date name || || ---------- ---------- ------------ -------- || -- Brian Tao (BT300, taob(a)netcom.ca) "Though this be madness, yet there is method in't"

Instability with full filesystems?

Has anyone noticed OnTAP 4.2a crashing when the WAFL filesystem uses up all available disk space or inodes? I was doing a series of ndmpcopies to several filers, with the intent to complete fill them to capacity with as many 2GB files as I could fit. One of the four filers crashed and rebooted early this morning: Tue Nov 25 06:00:04 EST [statd]: 6:00am up 14:40 1362 NFS ops, 0 CIFS ops, 0 HTTP ops Tue Nov 25 07:00:03 EST [statd]: 7:00am up 15:40 1362 NFS ops, 0 CIFS ops, 0 HTTP ops Tue Nov 25 12:37:32 GMT [rc]: saving 59M to /etc/crash/core.0-small ("trap 13 code = 0 eip = 196aad cs = 8 eflags = 10246 ") Tue Nov 25 12:38:04 GMT [rc]: saving 258M to /etc/crash/core.0 ("trap 13 code = 0 eip = 196aad cs = 8 eflags = 10246 ") Tue Nov 25 12:38:41 GMT [wafl_lopri]: file system is full Tue Nov 25 12:38:41 GMT [rc]: (out of disk space?)

Re: F630 4.2a CIFS unable to access snapshots?

Steve Losen <scl(a)sasha.acc.virginia.edu> writes: > We have a F630 running 4.2a and are having trouble accessing > snapshots with CIFS. This may be unrelated, but some NFS clients have problems using the .snapshot way of accessing snapshots. Apparently, Netapp returns the same NFS filehandle or at least the same inode number for snapshots as for the current version of the file, and this can confuse NFS clients. sodium:~ $ ls -i .profile 602274 .profile sodium:~ $ ls -i .snapshot/hourly.0/.profile 602274 .snapshot/hourly.0/.profile To work around this problem, we set up a separate NFS export of filer:/.snapshot that we mount under /snapshot/filer. That way, you can use a completely different mount point to recover a file and the inode problem is a non-issue. Since we've had people experience file corruption when using the .snapshot in their working directory, and no problems when using the separate mount point, I asked NetApp several times for an option to disable all .snapshots except for the root one. - Dan

630 Quad ethernet interface?
by Wayne 23 Nov '97

23 Nov '97

Hello, We received our first NetApp, a 630 with a slew of quad ethernet interfaces in it recently. My plan was to connect a number of Sun Ultra 2's directly to the filer using crossed ethernet cables. Also, Sun sells a QFE (Quad Fast Ethernet) card that supports the "trunking" of all four ports of this card which allows an 800Mb/s (100x4xfull duplex) connection toother compatible devices (other Suns, I assume some ethernet switches, etc.) Does anyone know if the quad ethernet controllers in the 630 can be configured this way? Also, has anyone benchmarked how much data a NetApp 630 can push to half a dozen to a dozen Ultra 2's that are directly connected via 100mb/s full duplex connections? Any tuning hints? I'd definitely appreciate learning from the collective experience. -- Wayne D.

backing up large filers
by matthew zeier 21 Nov '97

21 Nov '97

Has anyone found a "good" solution to backing up large filers? Someone convinced me that this ndmp thing was the way to go and I bought into the whole BudTool scheme (since they're the only ones supporting ndmp). I have an issue with that too - only one vendor. However, it's been nothing but a disaster and I'm looking for something far better. We've gotten the impression that no one at PDC has bothered to test BudTool with large filers with BreeceHill stackers (PDC and NetApp recommeneded these to us). There appears to be a general lack of interopibility. And finger pointing between Network Appliance and PDC. Right now we have an issue that keeps rebooting our filers every few days. Don't even talk about restoring data... as part of our general backup policy, we do periodic restores. I believe the wording from PDC was something to the effect that BudTool is a backup management software and not geared towards restores. Suffice it to say that we rarely have a successful restore. I'm basically fishing for alternative backup solutions. We have three F540s with ~100GB disk and about 20 other boxes with ~50GB or so each, all code development and all needs to be backed up. Any ideas? We're all pretty frustrated at the lack of a solid backup solution from Network Appliance. Hell, I'd go for something proprietary so long as it worked! - mz -- matthew zeier -- mrz(a)3com.com -- 3Com EWD Engineering -- 408/764-8420 ......................................................................

F630 4.2a CIFS unable to access snapshots?
by Steve Losen 20 Nov '97

20 Nov '97

We have a F630 running 4.2a and are having trouble accessing snapshots with CIFS. Our snapshot schedule is hourlies every two hours, keep 8, and keep 7 nightlies, so we usually have 15 lying around. We use both NFS and CIFS, with unix style file protection semantics. >From NT and W95, you can get into a share and use it just fine. If you browse the ~snapshot dir, you see all the hourly.* and nightly.* entries, but if you click on any of them, you get an access denied error box. If you "dir" the snapshot directory you see all the hourly.* and nightly.* entries, but if you dir any of those, they are empty. The live directory has plenty of files in it and from NFS, you can access files in all the snapshots. Again, the live filesystem works just as you would expect. It's only the snapshots that are giving us trouble. By the way, I posted an earlier problem about the set-group bit and later realized that I was not a member of my test file's group, so of course I couldn't set the set-group bit - duh.

Remote Backups
by Scott MacDonald 20 Nov '97

20 Nov '97

Toasties, Anyone any experiences of backing up one Filer to a remote tape (DLT) on another Filer? We're doing some testing now, and found that remote dumps are consistently three times slower than a local dump (restores too). Is this normal? We're also seeing about half as many packets coming back to the source Filer, is this really all protocol overhead? No-one else apart from me is using these Filers, and we're nowhere near capacity in terms of CPU, Network, Disk, or Tape I/O. Anyone got any experiences they can share? Many Thanks, Scott. -- _______________________________________________________________ Scott MacDonald Mobile Systems International Plc Tel: 0171 971 8798 System Administrator Fax: 0171 971 8712 E-Mail: scott(a)msi-uk.com _______________________________________________________________

locking problems?
by Alexei Rodriguez 20 Nov '97

20 Nov '97

Has anybody run into locking issues with their filers? Basically, we are seeing the following problems: - Sun Solaris 2.5.1 client tries to lock a file - the lock succeeds (it is the only client/process trying to get the the lock) - the process completes and attempts to release the lock - the process hangs because the kernel never clears the lock Our filer (f540, 8MB write cache, 256MB read) is running DataONTAP 4.2a. We are using NFS v3 over udp. hard mounts, noint. So, has anybody seen something like this? The common thread that all the processes have is that they are all perl scripts. I am looking at SunSolve for clues. Seems there have been some patches that touch on the locking. We will be testing these over the next few days. Oh, and all the lock problems started when we went from 4.01c to 4.2a. Any help would be appreciated. Thanks. Alexei
