Cluster failover exports problem..
by Greg Wilson 02 Mar '06

02 Mar '06

Hi I've got a problem with qtree exports after a Netapp cluster failover. Im running VCS (Veritas Cluster Server) on 6 Solaris hosts and im using the Netapp agent to manage mounting and unmounting qtrees from a clustered Netapp. Instead of listing your exports in the exports file you set it in your service group You allow it rsh to the filer and export the qtree to the host its running on. So if your group fails on host A, host B will rsh in and export the qtree to host B. This way it cannot be mounted on 2 hosts at the same time. The problem is after a Netapp cluster failover the filer reads the exports file off disk and all the qtrees that were exported before (in memory) are no longer exported and VCS just sits there waiting for it to come back. If we stop and start the service under VCS it comes back but this is not a good solution. What are people doing to get around this problem? How do the people who run VCS and Oracle handle this? thoughts ideas? here is the example.. mbe is a netgroup of 6 hosts.. /etc/exports file /vol/vol0/vmb01 -sec=sys,ro,root=mbe /vol/vol0/vmb03 -sec=sys,ro,root=mbe /vol/vol0/vmb05 -sec=sys,ro,root=mbe /vol/vol0/vmb07 -sec=sys,ro,root=mbe /vol/vol0/vmb09 -sec=sys,ro,root=mbe /vol/vol0/vmb11 -sec=sys,ro,root=mbe before failover these exports are setup by VCS rsh'ing into filer and running command Thu Mar 2 17:35:27 EST [cust-filer3: rshd_0:debug]: :IN:rsh shell:RSH INPUT COMMAND is exportfs -i -o sec=sys,root=mbe,rw=mcn05.msn,ro=mcn01.msn:mcn02.msn:mcn03.msn:mcn04.msn:mcn06.msn:mcn07.msn /vol/vol0/vmb11 /vol/vol0/vmb01 -sec=sys,ro,root=mbe /vol/vol0/vmb03 -sec=sys,ro,root=mbe /vol/vol0/vmb05 -sec=sys,ro,root=mbe /vol/vol0/vmb07 -sec=sys,ro=mcn02.msn:mcn03.msn:mcn04.msn:mcn05.msn:mcn06.msn:mcn07.msn,rw=mcn01.msn,root=mbe /vol/vol0/vmb09 -sec=sys,ro=mcn01.msn:mcn02.msn:mcn04.msn:mcn05.msn:mcn06.msn:mcn07.msn,rw=mcn03.msn,root=mbe /vol/vol0/vmb11 -sec=sys,ro=mcn01.msn:mcn02.msn:mcn03.msn:mcn04.msn:mcn06.msn:mcn07.msn,rw=mcn05.msn,root=mbe after failover.. note exports gone.. /vol/vol0/vmb01 -sec=sys,ro,root=mbe /vol/vol0/vmb03 -sec=sys,ro,root=mbe /vol/vol0/vmb05 -sec=sys,ro,root=mbe /vol/vol0/vmb07 -sec=sys,ro,root=mbe /vol/vol0/vmb09 -sec=sys,ro,root=mbe /vol/vol0/vmb11 -sec=sys,ro,root=mbe -- Greg Wilson Senior System Administrator greg.wilson(a)aapt.com.au

R100 with 256 meg cf card
by George, Andrew 01 Mar '06

01 Mar '06

I've tried to upgrade two r100's from 32 meg CF cards to 256 meg CF cards (so we can have a backup boot image with OnTap 6.5) On both occasions it's pretty much choked as soon as it's tried to see the 256 meg card and we've had to do some messing around to get a single image onto the card I'm beginning to think that an R100 running 6.4.x just can't see a 256meg cf card correctly and was wondering if anyone else has had a problem doing this?

Upcoming NetApp + BayLISA event
by Jennifer Davis 01 Mar '06

01 Mar '06

If you are located in the San Francisco Bay area, you may be interested in this upcoming event in March. It's open and free to the public, and pizza and beer will be catered by NetApp. March 16, 2006 Location: Network Appliance HQ, Building 3, 495 E. Java Dr Sunnyvale, CA 94089 Time: 7:00-10:00pm http://www.mollyguard.com/event/25445107 IP Storage Today and Tomorrow Speaker: David Dale, Network Appliance iSCSI Evangelist and Chair of the SNIA IP Storage Forum This session will highlight the progress made with iSCSI over the past 3 years and how next-generation features such as multi-connection sessions and ErrorRecoverLevel>0 are pushing iSCSI into more demanding application environments. Dave will also talk about where you can expect to see iSCSI next. (hint: think departmental Linux and UNIX environments) The Kilo-Client 1000 Host Swarm Speakers: Gregg Ferguson, Laboratory Administrator, and David Brown, Engineering Support Manager, of the NetApp Engineering Gregg and David from the NetApp RTP (Research Triangle Park) Engineering Laboratory will explain how they designed and built what is probably the world's largest iSCSI-based diskless server farm (1,000 nodes). Alll server nodes boot from NetApp storage using iSCSI and can be rapidly rebooted to run various versions of Linux, Windows, or other operating systems. Because a single LUN is shared among many servers in this design, server provisioning is almost unlimited. This session will describe the server farm in detail and discuss how particular technologies were chosen.

re:Malik Hafiz

Asalam Malekum As you read this, I don't want you to feel sorry for me, because, I believe everyone will die someday. My name is Malik Hafiz , a Muslim Caribbean Merchant in the Caribbean Island I have been diagnosed with esophageal cancer, which was discovered very late, due to my laxity in carrying for my health. It has defiled all forms of medicine, and right now I have only about a few months to live, according to medical experts. I have since lost my power of speech and can only manage to write now; as that has been the only way I am able to communicate.I have not particularly lived my life so well, as I never really cared for anyone not even myself but my business. Though I am very rich, I was never generous, I was always hostile to people and only focus on my business as that is the only thing I cared for. But now I regret all this as I now know that there is more to life than just wanting to have or make all the money in the world. I believe when the Almighty gives me a second chance to come to this world I would live my life a different way from how I have lived it. Now that I know my time is near, I have willed and given most of my properties and assets to my immediate and extended family members and as well as a few close friends. I want theAlmighty to be merciful to me and accept my soul and so, I have decided to give alms to charity Organizations, as I want this to be one of the last good deeds I do on earth. So far, I have distributed money to some charity organizations in the Caribbean Island, London and Ireland. Now that my health has deteriorated so badly, I cannot do this my self any more. I once asked members of my family to close one of my accounts and donate the money, which I have there to charity organization in Bulgaria, they refused and kept the money to themselves. Hence, I do not trust them anymore, as they seem not to be contended with what I have left for them. The last of my money which only few of them knows of is the huge cash deposit that I have with a security firm. I will want you to help me collect this deposit and dispatched it to charity organizations. Please if you are willing to help me and save me from this dilemma I am going through , do reply me on my email address (malikhafiz(a)k.ro)for more information which I will provide. May the Almighty be you and your family Amen. Malik Hafiz

Clicking FC9 Disks
by Ben Rockwood 28 Feb '06

28 Feb '06

Odd question for you guys. I've got a ton of FC9 shelfs on a variety of boxes, including an X86 VA Linux server, several on a Sun Ultra2 (for ZFS testing) and dozens of them on 2 FAS840's. All of them in this one room are doing the same thing, making this odd clicking noise. Its an odd sound, like a crackling noise, which at first I mistook for ice chips bouncing around in the AC ductwork. The sound doesn't seem good, but honestly, even though I've been around FC9 shelves for years, this is the first time I've had so many in such a quiet space. Perhaps this is a normal sound and I just couldn't hear it over screaming colo AC units before? The other thing that I find odd is that the same sound is coming from the FC9 disks on the FAS840's as from the shelves on my Ultra2 and VA Linux box. Clearly its not OnTap resetting disks. In all cases the disks are dead idle 99% of the time. The 840 is a nearline solution which snapmirrors at night, and the Ultra2 and VA box are just for filesystem testing. I'm really embarrassed that I don't know whats going on. Any pointers or similar experiences from anyone else? benr.

RE: I/O errors on FAS250
by Glenn Dekhayser 27 Feb '06

Michael: Are you running NIS? OR /etc/passwd authentication? Glenn -----Original Message----- Subject: I/O errors on FAS250 Hi. We've got a pair of FAS250 filers, and are running into a strange problem with one of them. In the past month and a half (or thereabouts), we migrated all the user home directories into a series of qtrees (splitting them across the two filers). Since then, on the older filer (running ONTAP 6.5.2R1) we see sporadically errors like this: mv: failed to preserve ownership for `/tufts/grad/fmoore03/.adobe/ AdobeFnt06.lst .lab118k': Input/output error mv: preserving times for `/tufts/grad/fmoore03/.gconf/apps/nautilus/ preferences' : Input/output error mv: failed to preserve ownership for `/tufts/grad/fmoore03/.microsoft/ ie5/Cookie s/fmoore03(a)dcs8ir0f010000oyioyaka1kl_8j7n(2).txt': Input/output error mv: preserving times for `/tufts/grad/fmoore03/.microsoft/ie5/ TempInternetFiles/ Content.IE5/GDQVAF2N/header-bg(1).gif': Input/output error We've gotten reports coming from people running on RedHat 9.0, RHEL WS 4 (Nahant Update 1) and Solaris 9. In all cases, it seems that if the user waits for 5 - 10 minutes, and then tries again, the problem has gone away. I've opened a call with Netapp's support department, but figured I'd see if anyone could shed any light on this. The messages file doesn't have anything unusual in it, nor does the weekly autosupport notifications. Given the intermittent nature of the problem, I'm not really sure where to start looking on this one. -Mike -- Michael Steeves | Unix Network Administrator mds(a)eecs.tufts.edu | Tufts University Department of ECE and CS Phone: 617-627-2601 | 161 College Avenue FAX: 617-627-3220 (Dept.
