Scripts (was RE: disappearing disks)
by Ben Rockwood 24 Apr '02

24 Apr '02

Several people have asked for my script, so I've put it on a web page. You can find it here: http://www.cuddletech.com/netapp/ Everything you need to know if on that page. Let me know if anyone has trouble with it, it should be very easy to use.

Older disks are more prone to this. I have a script that runs every Sunday and checks for errors in the messages files (any disk with more than 5 errors in a week gets manually failed) and then it checks the "fcadmin device_map" for "XXX". If that shows it flags it. Nothing special but it is something to let me know if a disk has spun down.

ssh authorized_keys on a NA
by Ozzie Sabina 24 Apr '02

24 Apr '02

Anyone know how (I figured you all would be quicker than looking on NOW) to put something like an authorized_keys file in place on a netapp? Basically I want to be able to ssh w/o password to our netapps as root on one box...I'd prefer to do it via an ssh key than via something like rhosts.allow. Thanks, Oz

Thanks Chris. Actually, we have seen this on our F840's as well, which have 36 Gb disks, but mostly on the 18's. We have a script that gets the disk count from the MIB's and compares that to what the total should be - if there is a discrepancy, we know what's happened. There won't be a discrepancy if the disk had failed as it should because it will still be counted in the total. -----Original Message----- From: Chris Blackmor [mailto:chris.blackmor@amd.com] Sent: Tuesday, April 23, 2002 9:47 AM To: Sam Schorr Cc: Server Team; toasters Subject: Re: disappearing disks Sam, If these are 18G drives they have a known failure problem where they just spin down.

We think this is a serious bug ourselves. It happens to more than spares - kinda weird behavior to be sure. That's why we have at least 2 spares per filer, and we jump all over failed disks. -----Original Message----- From: Stephen C.

We are running 6.1R1 and we have seen a frequent number of disks suddenly disappear without "failing" in the sense that the filer marks the disk as "failed". What we see is the disk is noticed as missing, there is a message to that effect in /etc/messages, but the disk does not show as failed in sysconfig -r nor does it show in sysconfig -d. If the disk is pulled and a new disk inserted, a "failed" message appears first, then the new disk is added as a spare. The original disk that went missing did have its data spared out. We have had to write our own monitoring scripts to pull disk counts from the MIB's so that this condition can be noticed right away. Netapp support says that this "never happens" but we have the /etc/messages files to show the problem.

disappearing disks
by Geoff Hardin 22 Apr '02

22 Apr '02

Fellow toasters; I have an F760 cluster running NetApp Release 6.1R1P1. In the past week, we have "lost" two disks on separate shelves. The disks seem to disappear from the filer and do not show up. All the disks are Seagate ST318203FC 18GB drives with firmware NA10. I've seen this happen before on spare disks, and the first disk we lost this week was a spare. Typically, the spare fails and just stops reporting; if you slip it into a different slot the disk reports as failed. No big deal, just a spare failing and the filer doesn't know what to do with it immediately. But yesterday, we lost a data disk; it actually didn't show up in the weekly cluster notification log that runs at midnight. Around 2pm we received a disk fail alert for the drive and a disk/shelf miscount error. While checking on this, I noticed a third disk, another spare, had "disappeared"; however, once the volume rebuild completed, this disk "reappeared." I was wondering if anyone else had seen similar behavior on their filers? Like I said, this is a cluster, and it's partner was still able to see the third disk that "disappeared", which leads me to believe I have an FC-AL adapter failing. All three disks have been on separate shelves, which also leads me away from suspecting an LRC (that would be too easy). Before I go tearing into the filer though, I wanted to see if anyone else had experience with this problem.

RE: Backup done on Remote Mirror Filer
by Chetrit Marc 22 Apr '02

Hi, We are using NETWORKER NDMP (NETWORKER UNIX 6.1.1, DATAONTAP 6.1.2R1) to backup mirrored volume, and it works with some limitation : Backup must be done on a snapshot for the mirrored volume, so you need to plan mirroring and backup to have an understandable backup process. Our configuration is made of 2 main filers mirroring one each other. By this backup method we get very good performance, and we need only one license (only one filer has a tape library connected). Restore process is a little bit complex, because you need to use relocate option of NETWORKER, but it works. There is also a limitation/bug in NETWORKER restore that make browse time difficult to use (in NDMP context). We choosed NDMP because it is the only way to reduce backup time. _____________________________________________ SIEMENS V D O Siemens VDO Automotive SAS A u t o m o t i v e BP 1149 1 Avenue Paul Ourliac 31036 Toulouse cedex 1 (France) Marc Chetrit OI ITS Back Office Phone : 33 (5) 6119 8421 Fax : 33 (5) 6119 2515 mailto:marc.chetrit@siemens.com <mailto:marc.chetrit@siemens.com> -----Original Message----- From: Alfred Lim [mailto:alfred@ptc.net] Sent: samedi 20 avril 2002 03:14 To: toasters(a)mathworks.com Subject: Backup done on Remote Mirror Filer Hi Toasters, Just wondering, have anyone ever perform backup on Remote Mirror Filer?

RE: Dead Disk Shelf for One of The Clustered Filer
by Knight, Jason 19 Apr '02

19 Apr '02

Nicholas, You are not being too paranoid. I removed clustering from all of our systems after we had repeated events (over a couple years each different and each "rare") that for one reason or another brought down two filers instead of just one. I must add here that this was shortly after clustering was offered (F630's using FC) although it continued up to F760's. I am not saying that clustering is bad, in fact when it worked it worked great. It does add another level of complexity to managing your systems and previously there were a lot of ways you could misconfigure yourself into a real problem. I have not had clustered systems for almost 2 years now and I do not miss them - but I am sure it has improved as most everything else has with the systems being produced by Netapp. It was a hard decision to make, but I reasoned that if you do not failover and it works who cares, it's when you need to failover and can't, or worse, bring down the partner also, that you are better off without it. Because really if you have a spare filer head with the right chip Intel/Alpha you could just put it in and go without worrying about any other dependencies. But to answer your specific question about shelves, I have never seen a shelf go bad and I am guessing it would take some external event to cause it to, such as excessive heat/cold or banging on it with a hammer. I have seen a disk (based on the RCA done by Netapp)chatter enough on a loop as it was going bad to bring down both system loops and hence both filers though.

By this I don't mean the power supply or fans because those are redundant and replacable. I thinking more of a board/ic failure or maybe shelf firmware bug that can completely knock out a disk shelf. If there is a remote possibility of this happening, then I figure the partner would not be able to take over the failed filer through channel B as well under a cluster environment. Am I being too paranoid? I'm looking for something like the Mean Time Between Failure (MTBF) for the Disk Shelf if available, be it FC9 or DS14. Any input would be greatly appreciated.

RFE 1287 - root=/rw= allowing NIS netgroups in exports file
by Chris Blackmor 19 Apr '02

19 Apr '02

Folks, I have just been informed about something that we have been discussing recently on toasters. The issue was exports allowing NIS netgroups to be used in the rw= and root= options on the exports of file systems. The above RFE was posted 7 YEARS AGO The reason for not allowing this was sited as performance issues. Well, we have come an awful long way with speed and abilities in this time. I think it is just plain silly that this RFE has been ignored for so long. Solaris allows this now and I don't think the issue will be resolved until enough people complain. It was suggested that I submit a case about this RFE which I am doing now. Unless it gets a bunch of requests it will continue to be ignored another 7 years. Anyway... if any of you want to hop on this bandwagon and get NAC to address the issue, it was suggested that we all enter cases about this. Soap Box Off.

If they can't place a BDC at the site with the mirrored Filer, then I guess they are just kind of out of luck. What would happen if they setup a trust relationship between the domains and set permissions to allow certain users from both domains?

Oops. I should have read your message more carefully. It's true that MultiStore will completely solve the problem of replicating the servers if the destination has a way to get to the proper domain infrastructure at the remote site. If not, then you will either have to reset permissions, as you say, or use local users on the filer. Even in those cases, using MultiStore is still advantageous since it allows you to keep the servers separate. Out of curiosity, why is it a problem to have the domain infrastructure available at the remote site? I'd think you would want that anyway as part of your disaster recovery strategy. Or is it just a question of one or two users at the remote site that need to access the data?

Hi All, I have two filers replicating data. The two filers are in different domains. Now if one of my site goes down( along with the PDC and BDCs of that domain), how will I be able to access the data of the mirrored volume on the remote site after breaking the mirror....... as the files will have permmissions of a different NT Domain. I cannot create NT 'Trust' or have a BDC of each domain on the remote site. Is there anyother way of doing this. Can I reset all the permissions on the mirrored volume in the remote site in case of a 'site outage', so that I can access the data there. Thanks Pramod

Gigabit Ethernet and Baystack 450
by devnull＠adc.idt.com 18 Apr '02

Fellow Toasters, I am planning on getting a gigabit module for my baystack 450 switch(its a 100Mb switch, with an expansion slot for GigE from nortel) and use the gigabit card on my F740, running 6.1.1R2. Is anybody done this before ? Was wondering if you could share your experiences, gotchas to look out for, oh-Sh*t's etc. The F740 has a gigabit ethernet Controller II in Slot 8. Any recommendations for reading to understand auto-negotiation etc. Thanks for your time. Regards. /dev/null devnull(a)adc.idt.com
