Hi Osvald,
If you physically replaced the failed disk with even a slightly smaller
disk in a RAIDZ pool and ran the zpool replace command, you would have
seen a message similar to the following:
# zpool replace rescamp c0t6d0 c2t2d0
cannot replace c0t6d0 with c2t2d0: device is too small
Did you run zpool replace or just physically replace the disk?
The pool would have been unhappy at that point and its possible that the
power failure wiped the disk labels.
Thanks for the information.

Hi Osvald,
Can you comment on how the disks shrank or how the
labeling on these
disks changed?
We would like to track the issues that causes the
hardware underneath
a live pool to change so that we can figure out how
to prevent pool
failures in the future.
Thanks,
Cindy
Hi Cindy!
I had recently replaced one of the three identical disks in my raid with a new one, the slightly smaller one, still a 1TB disk. This was named c14d0 in my case. The problems started after a power outage. After the power outage I couldn't import the pool. I'm pretty sure I had exported and imported the pool, but I'm not sure about this.
Other than this, I have no idea what could've caused the relabeling/resizing...
