You have mounted the same device to 3 different mount points; of course a
change in one will show up on the other.  It's the same as a bind mount.

That's a typo here, I was just trying to correct it at the same time that you
responded. 

mount /dev/cciss/c0d0p5 /mnt/p5
mount /dev/cciss/c0d0p6 /mnt/p6
mount /dev/cciss/c0d0p7 /mnt/p7

If this was a unique situation then I would agree that it could be pebkac
(problem exists between keyboard and chair) but it's occurred on 3 different
classes of servers: PC, DL320 and DL360. 

I've got a spare server that I can bring up and mount the other partitions.
Normally, only one partition is booted to at a time. Post-secondary VoIP lab
each student pair gets there own partition/PBX server to work on.
