Part of me wonders if "disks take a long time to mount" is a possible symptom
of a failing drive.  Do these drives have SMART capabilities?  If you have a
SMART monitor or reporter, you can look at the drive error statistics and see
how many bad block replacements have been made (not indicative of an error,
typically) and how many uncorrectable bad block errors (which are a problem).

I've used SmartMonTools on other systems to do monitoring and it works well.
