Hi,
zpool status reports my zones pool is corrupted. 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
