Hi

After Ubuntu 9.10 reinstall Pailimpsest Disk Utility won't/cant start my 3-disk RAID5 of 3x2TB Hitachi disks(encrypted).

Directly after the reinstall disk utility didn't recognize my RAID att all.

But after I installed mdadm, updated and restarted, ubuntu now recognizes parts of my RAID

Now if I press the "add" button and chose one of my 2TB disks I get the following error:


Error adding component: mdadm exited with exit code 1: mdadm: cannot get array info for /dev/md_d127


If I press the "Stop the array" button I get the options to also push the "Attach" and "Repair" buttons.
If I press the "Repair" button nothing happens, and if I press the "Attach" button I get the following error message:


Device is not a Linux md drive
