[OpenIndiana-discuss] zfs file system recovery

[Peter Firmstone]

Through sheer unimaginable good luck and nothing else, the resilvered 
disk has decided to play ball and the pool has come back online..,

It's currently performing a scrub, this time, I'll make sure I've got 
spare disks and backups aplenty.

BTW, What's the sparc version of OpenIndiania like?  Anyone on the list 
using it on a daily basis?

Thanks again,

Peter.
