I have a zpool with 2 mirrors of two disks each. 3 of the
disks are 1TB. I replaced three original 300GB disks with
the TB disks and there were no problems
Recently I upgraded to a new machine and trasferred the old
zfs disks to the new machine and everything was ok.
I then replaced the final 300GB disk with a 1TB disk. I
noticed that after resilver finished (in two hours), "zpool
status" kept showing 'replacing 0' and showed the old and new
disk in the pool. I thought it would automatically take out
the old disk? So then I manually "zpool detach"ed the old
disk but the size of the mirror has not changed.
Is this a bug or did I miss some step? I'd appreciate any help
to make the extra space usable! This pool is root so it
was mounted when I did this. May be that was the problem?
Thanks,
Bakul
