Presumably a 2.6 kernel? Which, and which distro version?
PG 8.1,
OK
ext3,
OK
RAID 1 setup with two controllers
Not enough info.
Soft RAID, controller RAID, IDE, SATA, SCSI U160, U320, SAS, 10K
RPM, 15K RPM, etc, etc?
And tape drive. What kind of tape drive?
Are the disks on one controller and the tape drive on another?

Is "common sense" really valid?
For example, it is "common sense" to white-power racists that
whites are superior to blacks, and that those with brown skins
are mud people.
However, that "common sense" is obviously wrong.
