Re: [zfs-discuss] Metadata corrupted

2008-04-28 Thread Siegfried Nikolaivich
Were you able to fix this problem in the end? Unfortunately, no. I believe Matthew Ahrens took a look at it and couldn't find the cause or how to fix it. We had to destroy the pool and re-create it from scratch. Fortunately, this was during the ZFS testing period, and no critically

[zfs-discuss] NFS and Tar/Star Performance

2007-06-10 Thread Siegfried Nikolaivich
This is an old topic, discussed many times at length. However, I still wonder if there are any workarounds to this issue except disabling ZIL, since it makes ZFS over NFS almost unusable (it's a whole magnitude slower). My understanding is that the ball is in the hands of NFS due to

[zfs-discuss] Saving scrub results before scrub completes

2006-12-26 Thread Siegfried Nikolaivich
Hello All, I am wondering if there is a way to save the scrub results right before the scrub is complete. After upgrading to Solaris 10U3 I still have ZFS panicing right as the scrub completes. The scrub results seem to be cleared when system boots back up, so I never get a chance to see

[zfs-discuss] Panic while scrubbing

2006-10-24 Thread Siegfried Nikolaivich
Hello, I am not sure if I am posting in the correct forum, but it seems somewhat zfs related, so I thought I'd share it. While the machine was idle, I started a scrub. Around the time the scrubbing was supposed to be finished, the machine panicked. This might be related to the 'metadata

Yeah, good catch. So this means that it seems to be able to read the label off of each device OK, and the labels look good. I'm not sure what else would cause us to be unable to open the pool... Can you try running 'zpool status -v'? The command seems to return the same thing: %

2006-10-09 Thread Siegfried Nikolaivich
status: The pool metadata is corrupted and the pool cannot be opened. Is there at least a way to determine what caused this error? Is it a hardware issue? Is it a possible defect in ZFS? I don't think it's a hardware issue because it seems to be still working fine, and has been for months.
