I ordered a "spare" drive so I'll wait until it arrives, replace the
faulty drive with this one by dd-ing data from one to the other (I have
only 4 SATA ports so I can't do "zpool replace").
zpool replace has two forms
zpool replace pool old-device new-device
and
zpool replace pool device
The latter is for when you pull the old drive and put the new one on
the same {S,P}ATA port because you've no free ports. I did that a
couple of weeks ago when one of my raidz drives fried (in its warranty
period!) and it worked like a dream. I did a zpool replace and then a
zpool scrub to make sure everything was OK because of this section of
the zpool man page:
Scrubbing and resilvering are very similar operations. The differ-
ence is that resilvering only examines data that ZFS knows to be
out of date (for example, when attaching a new device to a mirror
or replacing an existing device), whereas scrubbing examines all
data to discover silent errors due to hardware faults or disk fail-
ure.
Thanks for the tip. I'll be sure to try that.
