Thanks for the information. I also have my hard drives cooled (in
this case, each hard drive has three fans blowing across it.) I also
buy my hard drives locally and generally use Western Digital or
Maxtor. These drives are great; however, _any_ drive will fail
eventually. I'm just wondering if accessing /dev/hda and /dev/hdb
when they're in a software RAID (/dev/md) is possible when using a
tool like smartctl to retrieve the SMART information from each drive.
Even with all the cooling I have currently in the system, I've had
drives fail. I would like them monitored so that I can have a new
drive ready before the old drive dies. Using RAID mitigates the
problem to some extent, but it's not a complete solution.
I would test this out myself except that I have only one software
RAID system and it's in 24/7 production right now, so I don't really
want to mess with it without knowing exactly what will happen.
Thanks.
