Just looking for some advice, I had a server lock up that uses gmirror
for two RAID-1 arrays of the primary drive and a data drive. The data
drive was reported as degraded after a reset of the server, but is
rebuilding. It is comprised of two TB drives with one reporting ACTIVE
with no flags. The other synchronizing and taking days...

I ran the smartctl command below on the synchronizing drive and it seems
there are no errors? Should I trust this drive?
