[zfs-discuss] spa_import_rootpool: error 22
Hello, I've had a power kill on a server and the V880 cannot now mount the main root filesystem. I can boot the server into single user mode from the network. However, how can i rectify the corrupted ZFS disk ? Cheers. T.

You can select one of the bootable datasets in the list, after which detailed instructions for booting that dataset are displayed. Boot the selected dataset by following the instructions. This option is supported only when the boot device contains a ZFS storage pool. This should hopefully give you a list of datasets that are available. If nothing comes up, do a 'boot net' or 'boot cdrom' of a recent Solaris 10 Update, and once you're at the shell prompt, do a 'zpool import' to get a list of importable pools. ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] Cannot remove zil device
I have a pool that is experiencing the same problem (currently at version 26). I've been able to remove zil devices from it before but at some point they become stuck. The zpool remove command completes with no error, but the device is never really removed and remains in the pool. zpool iostat will show no activity to the device however, and the alloc column shows 16.0E. It is possible to do a zpool replace on the device, but the replacing device will end up in the same state (unusable and unable to be removed). I had a similar problem that turned out to be a PEBKAC - I tried to remove devices in a mirror, not the mirror with the devices... Can you paste the command(s) you're using for this? Btw, log device removal is in from zpool v19, so the one you're using should work.

Re: [zfs-discuss] Cannot remove zil device
You can add and remove mirrored or non-mirrored log devices. Jordan is probably running into CR 7000154: cannot remove log device Thanks, Cindy On 03/31/11 12:28, Roy Sigurd Karlsbakk wrote: http://pastebin.com/nD2r2qmh Here is zpool status and zpool version The only thing I wonder about here, is why you have two striped log devices.
