I tried recreating the array, but it won't mount...
Also a bit weird is that I did a SMART short self-test, and one of the
drives keeps returning a Read-Failure, but the overall SMART status is
passed. Could this be from overheating?
I'm not sure. If those Read-Failure are error counts, than yes, I think
so. The drive is currently OK, but when it had a lot of activity it
overheated and started getting read errors.
Actually what I'm saying is that I ran smartctl and did a short test on
the drive, and it keeps returning a read error at a certain porint (LBA
271739730). I let it cool off for a few hours, and tried the test
again, same thing.
Does this mean that the drive has developed bad sectors and needs
replacement? These are brand new drives. The error only happens on 1
of the 4.
Would letting it cool off fix
things, or should I call in for warranty?
Array creation creates a lot of activity for the drives, and it could
cause them to overheat. Or cause energy flutuation if the PSU isn't
powerfull enough, but I'd expect PSU problems when booting, not when
writing/reading.
I have an older system where I have to keep DMA disabled for my drives
or the system locks when cron starts updatedb or someone copies a large
file, thus my suspicion that your drives are also overheating.
About calling in for the warranty, I'd first try hddtemp
(http://www.guzu.net/linux/hddtemp.php) and if the temperature does
rise, then some more fans. :)
I tried to get hddtemp, but alas, no compiler available in rescue mode.
I will try Knoppix.
