And you can always mount it as ext2 if you think the journal is corrupt.

Have you considered Raid-6 rather than R5?

The biggest worry I have is having a 2nd disk fail during a
reconstruction. True, you lose another disks worth of space, but disk is
cheap these days, right? :)

Especially with 12 disks in the array.

What I do now is do a read-only badblocks test on all the
drives/partitions in a set if I ever have a drive failure. That way I will
know in advance if a disk is going to fail during the reconstruction -
however, this takes time (and can severely impact performance) but
hopefully the time window between checking the disks and the
reconstruction would be small enough that another disk shouldn't go
faulty...
