I've encountered these sorts of problems when upgrading SmartOS versions and there being core dumps left over from previous versions. The format can change between SmartOS versions and it can't be read so corruption is assumed.
It could be something else, but that's the only time I've encountered this.

It seems 2 blocks went bad (see below for more details): errors: Permanent errors have been detected in the following files: <0x4865>:<0x1> <0x6f7a>:<0x1> That's really strange since mirroring is active. Could this be zfs not writing the right data on both disks? My Supermicro server is running joyent_20131003T221245Z kernel At this time, I can see no effect on running VMs. Is the corruption happening outside of filesystems/volumes actual data? how could I try to recover from this situation? I have 4 new disks and would like to clean up the pool. Would something like this be correct: zpool create zones2 mirror <ndisk1> <ndisk2> mirror <ndisk3> <ndisk4> zfs snapshot -r zones@snap zfs send -Rp zones@snap | zfs receive -u zones2 <stop all vms> zpool export zones zpool import zones2 zones Thanks, - Michel zpool status -v pool: zones state: ONLINE status: One or more devices has experienced an error resulting in data corruption. Applications may be affected. action: Restore the file in question if possible. Otherwise restore the entire pool from backup. see: http://illumos.org/msg/ZFS-8000-8A scan: scrub repaired 0 in 4h16m with 32768 errors on Mon May 12 14:14:03 2014 config: NAME STATE READ WRITE CKSUM zones ONLINE 0 0 0 mirror-0 ONLINE 0 0 0 c1t50000394183AFC96d0 ONLINE 0 0 0 c4t50000394183AE482d0 ONLINE 0 0 0 mirror-1 ONLINE 0 0 0 c2t50000394183AE50Ed0 ONLINE 0 0 0 c5t50000394183B0B86d0 ONLINE 0 0 0 logs mirror-2 ONLINE 0 0 0 c0t5E83A97059BABF17d0s0 ONLINE 0 0 0 c0t5E83A97059BABF12d0s0 ONLINE 0 0 0 cache c0t5E83A97059BABF12d0s1 ONLINE 0 0 0 c0t5E83A97059BABF17d0s1 ONLINE 0 0 0 errors: Permanent errors have been detected in the following files: <0x4865>:<0x1> <0x6f7a>:<0x1> smartos-discuss | Archives<https://www.listbox.com/member/archive/184463/=now> [https://www.listbox.com/images/feed-icon-10x10.jpg10f3ec5.jpg?uri=aHR0cHM6Ly93d3cubGlzdGJveC5jb20vaW1hZ2VzL2ZlZWQtaWNvbi0xMHgxMC5qcGc] <https://www.listbox.com/member/archive/rss/184463/25738179-216c4b5f> | Modify<https://www.listbox.com/member/?&;> Your Subscription [https://www.listbox.com/images/listbox-logo-small.png10f3ec5.png?uri=aHR0cHM6Ly93d3cubGlzdGJveC5jb20vaW1hZ2VzL2xpc3Rib3gtbG9nby1zbWFsbC5wbmc] <http://www.listbox.com> ------------------------------------------- smartos-discuss Archives: https://www.listbox.com/member/archive/184463/=now RSS Feed: https://www.listbox.com/member/archive/rss/184463/25769125-55cfbc00 Modify Your Subscription: https://www.listbox.com/member/?member_id=25769125&id_secret=25769125-7688e9fb Powered by Listbox: http://www.listbox.com
