zfs discuss - Mar 2011 - 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.

At the OBP''s ''ok'' prompt, try a ''boot
-L'':

    -L
         List the bootable datasets within a ZFS pool.   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.
