For anyone who can help me here is some more information on my linux
raid partition problem.
As stated before, I only have two disks from a three disk raid 5.
When I try:
mdadm --assemble /dev/md0 /dev/hdd2 /dev/hde2
I get the following error:
mdadm: cannot open device /dev/hdd2: No such file or directory
mdadm: /dev/hdd2 has no superblock - assembly aborted
When I do a mdadm examine, I get a different number of events:
mdadm --examine /dev/sdd2 | egrep Event
Events : 60541
mdadm --examine /dev/sde2 | egrep Event
Events : 60544
Also mdadm examine gives different States:
mdadm --examine /dev/sdd2 | egrep State
State : active
mdadm --examine /dev/sde2 | egrep State
State : clean
But mdadm shows that their Magic and UUID numbers are the same.
Can anyone give suggestions on how I can repair this?
Here are the full mdadm --examine outputs:
mdadm --examine /dev/sdd2
