Maximum number of quota entries?
by Brian Tao 04 Dec '97

04 Dec '97

How many lines can I have in /etc/quotas? Is it limited by memory or CPU? Is there a performance hit the more quotas I apply? I may have need for 2000+ user quota entries on an F210 with 256MB read cache. -- Brian Tao (BT300, taob(a)netcom.ca) "Though this be madness, yet there is method in't"

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.

Is there anyway to change the HOST SCSI ID of the tape drive SCSI adapter?
by Andrew Bond 25 Nov '97

Jaye, this should be in the toasters archive (see the following message from Brian Tao). The utility that Dario mentioned is on Quantum's website, or you should be able to use scsi commands, as Brian suggests.

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?
by Brian Tao 25 Nov '97

25 Nov '97

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?) Tue Nov 25 07:38:51 EST [rc]: relog syslog 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 07:38:51 EST [rc]: NetApp Release 4.2a boot complete. Tue Nov 25 07:38:52 EST [asup_main]: System Notification mail sent There wasn't enough room to save the large core file, but the small one appears to be intact. I saw something similar happen on a different filer when it ran out of inodes (unfortuately, I didn't save a copy of the panic message). If the crashes are related to full filesystem conditions, I won't worry about it too much. Just curious. ;-) -- Brian Tao (BT300, taob(a)netcom.ca) "Though this be madness, yet there is method in't"

Re: F630 4.2a CIFS unable to access snapshots?
by Daniel Quinlan 25 Nov '97

25 Nov '97

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
