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

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!!

RE: AIT libraries
by Premanshu Jain 12 Sep '00

Yes Qualstar's are really good. We are implementing them now. We could dump 105 GB (Unix format data) on a AIT2 tape. This compression depends on the type of data you are backing up. The CIFS data blocks dumped only upto 60-70 GB per tape. -----Original Message----- From: Larry Goodman [mailto:Larry.Goodman@Intense3D.com] Sent: Tuesday, September 12, 2000 6:45 AM To: toasters(a)mathworks.com Subject: AIT libraries 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: 2 volumes or 1
by Walters, Mike 11 Sep '00

You don't mention what size drives they are (9/18/36GB). As a rule, however, I would suggest that you are correct in thinking you would be better off combining disks to make a single volume. You can use qtrees to segragate data (& give more control if some is NFS & some CIFS, for example). I believe that your 'heavy reads & writes' will benefit from the larger raid group. You would obviously need to destroy vol1 before adding disks to vol0. Just one minor point - I presume you do have a spare disk as well - if not, & you have a disk fail, the filer will squawk at hourly intervals complaining, then if you don't add a drive, shutdown after 24 hours (options raid.timeout defaults to 24 [hours] to configure this) on the basis that you don't want to run degraded for any significant time. Cheers Mike UK SE -----Original Message----- From: Pesce, Nicholas (FUSA) [mailto:Nicholaspesce@firstusa.com] Sent: 11 September 2000 21:30 To: 'toasters(a)mathworks.com' Subject: 2 volumes or 1 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: Restricting CIFS

The WINS server must be able to ping each interface on the filer that you want to register with WINS. In situations like you describe where you have a private network that should not be registered with WINS, then you need to turn off WINS registration on that interface. You do that by adding a -wins parameter to the ifconfig for the interface. ~~~~~~~~~~~~~~~~~ mailto: hawleyr(a)netapp.com US Mail: Network Appliance Inc.
