When I mean about the error is:
Where a system crashes, zfs just loses its references and thinks that disks are
not available.
When in fact the same disk worked perfectly just before the motherboard crash.
Not just asking. Isn't ZFS supposed to cope with this kind of crash ?
There must be a way of diagnosing what is going on.
Here is the description of the label when I change configuration of the hdd.
What I did is just add another SCSI controller and added 2 disks.
bash-3.00# zdb -l /dev/rdsk/c4t1d0s0
