What kind of hardware failure may it be? smartctl -a /dev/ada2 shows
disk is fine.
I had a new WD drive recently that had a write error. Reallocated
sector count did not go up, but it quickly failed the SMART self-test,
short or long. See smartctl(8) about the -t parameters.
this is WD "green" 3TB
1T Red here. The firmware is likely very similar.
The same here: brandnew WD 2T green, 9.1 stable, svn rev. 244773, not using
GEOM. I had that problem two times within the last two weeks, but the smart
self tests can not find any errors/bad sectors.
Hmm. The green drives are supposed to go to sleep for power saving, and
then there's a multiple-second delay when they have to spin back up on
access. That should not be a problem for gmirror, but maybe it is.
sysutils/ataidle can turn on the spindown. Some drives do not accept
that command, or claim to accept it but ignore it. Worth a try, though.
