Re: Setting up Quota's with SecureShare Quota Manager 2.0
by Seth Moskowitz 26 Jul '01

26 Jul '01

Michael, I have tried to do something very similar to this although I have not used the SecureShare Quota Manager and do not anything about it. I do however know that although OnTap 6.1 supports SID based quotas it only suports this for users. It does not support SID Group quotas. Does the SecureShare Quota Manager get by this? If so it is something I proably need to look at, If not then I do not believe what you are trying to accomplish can be done.

RE: autosupport full of junk

Hi Frank, The output that is being referred to is actually XML, and it is generated by the EMS subsystem in OnTap. The reason it is there is to allow automated triage of problems that might occur on a filer. Because XML is a structured format, it is easier to write software to process it instead of the relatively unstructured output that appears in /etc/messages.

How many of you out there are using SQL 7.0 SP3 under Win2K on a Filer? What series of Filer do you have and what have your performance statistics looked like compared to local attached storage.

autosupport full of junk
by Jim Harm 25 Jul '01

25 Jul '01

How do others feel about the junk in autosupport? I see the entire messages file reproduced to three times the size just to put it into html format; why don't they run the script to put it into html when they want it and at NetApp instead of cluttering MY weekly reports? These FC stats can be produced once a year when there is a problem to analyze. The disk list doesn't have to be reproduced any more often than when there is change to the list. I think it is unnecessarily large and wading thru it to look for a current interesting event would be easier without it. I have been asking for options to autosupport with the customer support for over a year. I am occasionally told it will be in a future release as yet un-named. Maybe they need to hear more noise. -- }}}===============>> LLNL James E. Harm (Jim); jharm(a)llnl.gov System Administrator Compaq Clusters (925) 422-4018 Page: 423-7705x57152

ndmpcopy level i problems

I am having problems doing an imcremental ndmp copy from one filer to another. The first level i goes fine. The second one a few days later gives this error: filer1: CONNECT: Connection established. filer2: CONNECT: Connection established. filer1: LOG: DUMP: filer1: LOG: creating "/vol/vol0/../snapshot_for_backup.828" snapshot. filer2: LOG: RESTORE: filer2: LOG: Could not create /vol/volhome1/etc/tmp/restore.clrimap.184.time_996070293.pid_23341776 filer2: LOG: RESTORE: filer2: LOG: Cannot restart restore without a dumpmap. filer2: LOG: RESTORE: filer2: LOG: RESTORE IS ABORTED filer2: Connection halted: HALT: Internal error! It appears that in the etc/tmp dirs on the target filer volumes there should be files created after each ndmpcopy called dump.dirlist and dump.bitmap but on some of the target volumes they not there. some target volumes do have these files and those volumes will do incremental copies. All initial copies completed successfully with no errors. Does anyone have any ideas why these files were not created?? The command I am using for both is: ndmpcopy -level i filer1:/vol/vol0/ filer2:/vol/volhome1/users2/

RE: .nfsXXXX files cause ClearCase remove commands to fail ...
by Fox, Adam 24 Jul '01

24 Jul '01

It's not configurable, it's not even a filer-specific thing. Those .nfs files are being created because some other process out there is currently accessing the file that you asked to be deleted. That's what causes .nfs files. It's part of the NFS spec to do so. If they are still around after the client is no longer accessing the file, then the client did not delete them which again, according to the spec, it the client's responsibility. At that point, you can delete them manually.

.nfsXXXX files cause ClearCase remove commands to fail ...
by John Sambrook 24 Jul '01

24 Jul '01

We have a couple of Sun servers running ClearCase version 4.2, patch level 3, with a NetApp F740 filer providing VOB and view storage. We host VOB databases on the filer as well, not just pools. When we attempt to delete a VOB, using the ClearCase "rmvob" command, the command fails. Upon investigation, it appears that the filer is creating .nfsXXXX files, corresponding to files that were open at the time they were deleted. I'd like to know if others have encountered this problem, and if so what they did to resolve it. Perhaps the creation of these files is configurable? Thanks for any advice.

Setting up Quota's with SecureShare Quota Manager 2.0
by Grey, Michael 24 Jul '01

24 Jul '01

Has anyone had experience setting up quota's on a filer running 6.1R1 using SecureShare Quota Manager 2.0 What I would like to do is have 3 levels of quota's (High - 500Mb, Medium - 350Mb, Low - 200Mb) established. These would be established via a Global group in Windows NT. For example: you are a member of the Medium Global Group you would receive a home directory with a quota of 350Mb. We have approximately 2000 users and I would rather manage the quota system based on being a member of a Global Group if possible. The volumes will be configured as CIFS Has anyone had experience setting up quota's to work with NT Global Groups and if so, is there any thing special to look out for?

Filer burn-in testing

Sounded interesting, and I'm curious how things have progressed in the last four years. Anyone from NetApp able to comment on the current state of these programs? TIA.

Symlink support in ftp server
by Mike Sphar 24 Jul '01

24 Jul '01

Does anyone know if it's possible for the ftp server on a netapp to allow symlinks to point outside the root directory? I realize there are security reasons for normally not wanting this, but I've got a few scattered directories on my filer that I'd like to make available via anonymous ftp, and I'd rather not have to rearrange the data on the filer or make copies of the files. I'd hoped to create an anonymous ftp directory and create symlinks in it to point to the directories I want to make available. However so far that hasn't seemed to work. I've poked around a bit on NOW but haven't found any reference to this possibility.

general filer gripe
by Leonard, Roger 22 Jul '01

22 Jul '01

This is probably covered in NetApp 101 but never having taken the classes (yet) I need something clarified. Environment: Sun solaris with automounter and different flavors of filers running ATM and LANE. i mucked up the networking portion of the rc file and the filer was essentially hung trying to export filesystems. it could not resolve the addresses to these hosts because it could not get dns or nis or any name resolution or even a default route for that matter. It hung while complaining for over an hour. so i could not get in through my normal "cd /net/filername/etc" my final recourse was to create boot floppies, boot from them, selecting "boot without rc" bringing up networking with ifconfigs and elconfigs, then going in through "cd /net/filername/etc" and editing the rc file accordingly and rebooting. very slow and tedious. My basic question is: was this the proper way to fix a screwed up rc? boot floppy manually config network cd /net/filername/etc edit rc Or is there a way to edit the rc file from a terminal session? or any other of the /etc files? what is the quickest way to recover from this type of problem?? can i boot the filer kernel in single user mode without networking? What is the best way to get around this problem in the future? Can i make the exports fail and just come up to a prompt or do i have to boot floppy everytime? if i hardcoded my export hosts in the /etc/hosts would the filer come up even without networking and NIS/DNS, etc? thanks Roger D.

RE: general filer gripe
by Mike Sphar 20 Jul '01

Except that my configuration files had already been changed during the Ontap upgrade, obviously, as the machine wouldn't operate on the network after rebooting, so I had no idea of knowing what else was messed up in the config files. I had to operate on the assumption that everything was in an unknown state, not just the network interface, so I got the basic configuration reset quickly and then brought the system up and reviewed all the settings afterwards, pulling some back out of snapshots and resetting others manually. Depending on how much of the configuration was lost, I might have also lost the hosts file or name resolution or NIS configuration info, for example, and ifconfig wouldn't have fixed that, and the filer wouldn't have known who the admin host was, which would have simply sent me back to the console to fix more stuff and left the system down longer. In my experience, it's sometimes better to minimize downtime by trying a solution that will quickly cover many potential problems rather than investigate and repair one problem at a time.

pegged filer....write bound?
by Todd C. Merrill 20 Jul '01

20 Jul '01

Scenario: clustered F840's, ONTAP 5.3.7R2 one is a busy filer of mostly home directories other is fine, no problems, much less loaded middle of the day, response takes a nosedive on the busy one CPU is pegged at 100% very little NFS, CIFS, or network traffic no backups or restores going on no snapshots in progress (that we can tell) As a user, response is *extremely* slow; sometimes a stat of a known populated directory returns empty. Effectively the filer is not serving data. (Worse, in my opinion, that it returns the *wrong* data.) We turn off NFS to see if that is the culprit. Still CPU is pegged. We terminate CIFS to see if that is. CPU drops down, but not to zero. We have only NFS, CIFS, and cluster licensed (i.e., no HTTP). Here's what we saw: home> sysstat 2 CPU NFS CIFS HTTP Net kB/s Disk kB/s Tape kB/s Cache in out read write read write age 10% 0 0 0 10 6 12074 0 0 0 24 47% 0 0 0 8 5 6369 7 0 0 24 47% 0 0 0 13 7 16479 20258 0 0 24 33% 0 0 0 4 3 11858 13180 0 0 24 34% 0 0 0 8 4 12698 14703 0 0 24 9% 0 0 0 9 5 11392 8 0 0 24 9% 0 0 0 7 4 11097 0 0 0 24 58% 0 0 0 9 3 6453 2415 0 0 24 39% 0 0 0 7 2 15218 17034 0 0 24 39% 0 0 0 5 2 13560 16924 0 0 24 31% 0 0 0 9 5 11633 11593 0 0 24 8% 0 0 0 8 4 10634 8 0 0 24 10% 0 0 0 9 5 12992 0 0 0 23 62% 0 0 0 8 3 9828 8030 0 0 23 44% 0 0 0 9 4 17156 19024 0 0 23 37% 0 0 0 6 3 15229 17994 0 0 23 9% 0 0 0 6 2 12204 8 0 0 23 10% 0 0 0 11 5 13574 8 0 0 23 66% 0 0 0 5 3 9354 11421 0 0 23 Pardon my French, but WTF is this filer doing? It looks and smells like snapshot behaviour, but we weren't even near to the time it should be doing a snapshot via the schedule. No external scripts would initiate one, either. Our solution was, unfortunately, a reboot. The second time this happened, we grabbed some output from `wafl_susp` to check on the consistency points, since we are suspecting this poor filer is write-bound (insufficient NVRAM cache--half is "lost" to the partner for clustering). The counts of all the cp_* parameters show *less* than the minimum number of consistency points expected (uptime times 6 per minute, i.e., a minimum of once every 10 seconds). And, of course, lots of cp_from_log_full and cp_from_cp. Anybody seen anything like this? Any idea what is going on? Are we just beating the crap out of this thing, and it gives up the ghost by pretending it is busy to avoid doing anything else? (We've already got another clustered pair of F840's in house, in testing, soon to be deployed. Not soon enough. Figures.) Until next time...

Roger, Assuming you can get to the filer's console, you could list the rc file using "rdfile /etc/rc" and then re-create it using "wrfile /etc/rc". Be warned, however, wrfile completely wipes out the existing file and you will need to re-enter every line. It's as if you did "cat > /etc/rc". But if you are using a terminal where you can do cut & paste, paste the original text up to the point where you need to make the change, make the change, and then paste the rest of the file. Remember to hit Control-C on a blank line to exit wrfile. wrfile is very basic, but effective in situations like the one you described.

RE: Corruption in data

This is bug 8075. It's fixed in 6.0 and later releases.

He opens a file in textpad, saves it then uses the file in an application and finds it has null characters in it. I checked through and found he had run out of quota. I increased this and all appears to be well. My question is - can low or no disk quota cause data corruption?

Novell on NetApp, is it workable longterm?
by Robin Croley 19 Jul '01

19 Jul '01

Does anyone have any experience integrating Netware 5.1, NDS 7 and Groupwise 5.2 with a Filer? I sell NetApps in Dallas and need war stories, feedback, testimonials, and any other info for a potential client that has roughly 20 Novell servers, 36 NT boxes, and 9 or 10 Unix machines. They have no plans to retire Novell anytime soon, so need a long-term workable solution instead of a planned migration scenario.
