Re: [zfs-discuss] Troubleshooting help on ZFS
Thanks for everyone who replied to my call for help. I really appreciate it. I turned the server off for a few hours and rebooted again. This time many of the problems seemed to resolve. It has been running smoothly now for a day. I took the advice of one post and updated to OpenIndiana build 148 as that seems the most promising upgrade path at this point and it has a more recent version of ZFS which hopefully will be more stable. THanks again. -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

It is running on a tower with 6 HDD configured in as raidz2 array. Motherboard: ECS 945GCD-M(1.0) Intel Atom 330 Intel 945GC Micro ATX Motherboard/CPU Combo. Memory: 4GB. I set this up about a year ago and have had very few problems. I was streaming a movie off the server a few days ago and it all of a sudden lost connectivity with the server. When I checked the server, there was no output on the display from the server but the power supply seemed to be running and the fans were going. The next day it started working again and I was able to log in. The SMB and NFS file server was connecting without problems. Now I am able to connect remotely via SSH. I am able to bring up a zpool status screen that shows no problems. It reports no known data errors. I am able to go to the top level data directories but when I cd into the sub-directories the SSH connection freezes. I have tried to do a ZFS scrub on the pool and it only gets to 0.02% and never gets beyond that but does not report any errors. Now, also, I am unable to stop the scrub. I use the zpool scrub -s command but this freezes the SSH connection. When I reboot, it is still trying to scrub but not making progress. I have the system set up to a battery back up with surge protection and I'm not aware of any spikes in electricity recently. I have not made any modifications to the system. All the drives have been run through SpinRite less than a couple months ago without any data errors. I can't figure out how this happened all of the sudden and how best to troubleshoot it. If you have any help or technical wisdom to offer, I'd appreciate it as this has been frustrating. look in /var/adm/messages (.*) to see whether there's anything interesting around the time you saw the loss of connectivity, and also since, then take it from there.

This sounds exactly like the problem that I had with the Realtek controller on a D945GCLF2. Look into using the gani drivers instead of the shipped realtek drivers. -B -- Brandon High : bh...@freaks.com ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
