AIT libraries
by Larry Goodman 13 Sep '00

13 Sep '00

If any of you kind toaster'ites have experience with AIT2 tape libraries, I'd like to here your advice about the different brands available. I've been researching these devices and they all seem to claim pretty much the same specs (duh, they're all using the same Sony drive!). I'm particularly interested in the durability of the robotics. I've been looking at libraries from Spectra Logic, Qualstar, Adic and Overland Data, usually providing from 12 to 24 slots (single drive). The Qualstar folks claim that they're the only supplier that uses a "lead-screw" design instead of belts for better reliability. Any comments? Thanks, Larry.Goodman(a)Intense3d.com

RE: Solved (Was [toasters] Problems with quotas )
by Davis, Barry 13 Sep '00

13 Sep '00

Just an FYI...NetApp has put a "Panic Message Analyzer" onto the NOW site at http://now.netapp.com/NOW/pmsg/pmsg.cgi I pasted the Panic message below into the analyzer and it came up with the same conclusion: Bug Identified: 26472 Bug Title: quota on/resize can panic the machine Description: If user or group names are specified in /etc/quotas and a name cannot be resolved using /etc/passwd or NIS, the filer will panic when reading the quota names file during a quota resize or quota on. Workaround: Avoid doing quota resize and quota on, or use numeric ids to specify users and groups, or make sure any names used will resolve. Suggestion: Upgrade to release 5.3.6R2 Let the Release Comparison Tool show you the differences between 5.3.6R1 and 5.3.6R2. Download the suggested release. > -----Original Message----- > From: kubek [mailto:kubek@insa-tlse.fr] > Sent: Tuesday, September 12, 2000 3:00 PM > To: toasters(a)mathworks.com > Subject: Solved (Was [toasters] Problems with quotas ) > > > > Thanks to the list ... > > I received many answers : one solution is to reboot the netapp with > floppy, at the menu choose "boot without /etc/rc" then delete the > offending quotas file.

OID's and MIB's
by Demon Toasters Exploder 13 Sep '00

13 Sep '00

Hello all, I've been recently twiddling about with some snmp monitoring of the funky netapps we have here. The big problem I've fallen over is the complete lack of details when it comes to lists of OID's and specific snmp queries you can make. I need a list of all the things that can be queried on the Netapp, I've managed to pull bits and bobs from the mib and other sources, but the biggest one I've had so far is find entries for Bytes/s per interface (the same for collisions/errors). Are there such entries for load, tempuratures and so on? I've trawled now.netapp, a few FAQ's and also the archived mailing list without much joy :( Any lists or pointers in the right direction would be appriciated.

2 volumes or 1
by Pesce, Nicholas (FUSA) 13 Sep '00

13 Sep '00

Gentlemen, I need your opinion on a creation I am about to unleash on our unsuspecting production site where I work. I currently have a 740 filer with 2 shelves and 7 disks. 3 disks are in the first shelf and configured for volume 0 root volume 4 disks are inthe second shelf and configured for volume 1 Now, since I didn't put this box together. I was wondering if it is better to make all of these disks one volume. There are heavy reads and writes to the volume1, but I don't know if having a heavily used volume combined with root functions will kill my performance. Besides this will make a larger volume for more distributed writes (8 total disks versus 4). Also I will be saving 1 disk of data space because I won't need the second parity disk. Addition information is that they are fibre channel shelves (of course). And that the data is not important (washed away daily). Assuming that the root volume functions do not critically affect my box (and I don't believe that they do, as most of it is running from memory) I believe my choice is correct. Just wondering if you guys agree with this hypothesis or not. Nicholas Pesce Internet Production Services Phone: 847 488-6384 Pager: 888 785 3455 Fax: 847 488 3434

RE: [toasters] Problems with quotas (or Hurrah ! my first core du mp )
by Fox, Adam 12 Sep '00

12 Sep '00

This looks like a bug in 5.3.6R1. If you do a user level quota and the user is not in the /etc/passwd file or NIS map, it panics the filer at the quota on. Worse, it keeps panicing at each reboot since part of the reboot sequence is to initialize the quotas. To fix. Boot floppy, then boot without rc (option 2). You'll need to upgrade ONTAP to 5.3.6R2 which has the fix. This one seemed to creep in right at 5.3.6R1 and was fixed with anything after that. Previous released do not seem to have the problem. Hope this helps. -- Adam Fox NetApp Professional Services, NC adamfox(a)netapp.com > -----Original Message----- > From: David Schairer [mailto:njal@concentric.net] > Sent: Tuesday, September 12, 2000 3:08 PM > To: kubek > Cc: toasters(a)mathworks.com > Subject: Re: [toasters] Problems with quotas (or Hurrah ! my > first core > dump ) > > > Boot via floppy, remove the /etc/quotas file.

[toasters] Problems with quotas (or Hurrah ! my first core dump )
by kubek 12 Sep '00

12 Sep '00

Hi, I just populated our F720 but noticed that I forgot some "quota off -- quota on" command sequence in order to enable the last modification i did on quotas... ... I'm still waiting for the output of the "quota on" command as since then the filer is cyclicly trying to dump core (see screenshot at the end of this message) : After each boot the filer notices that the "quota on" command was interrupted by a reboot, it tries to initialize the quotas and then ... reboot Does someone on this list know how to break this cycle ? Either by modifying the quota file (throught the floppy boot menu) or by forcing a reboot *without* quota initialization ?

Please check bug number 26472 This is probably caused by an error in the quotas file. this is fixed in 5.3.6R2 Quick suggestion is boot from floppy upgrade to 5.3.6R2 and find the error in quotas file!! Please check with support on this if you have a case open!!
