hi!
i've ran into some problems with mdraid and lvm. as i guess that log
messages will give you more information than i might do, i will begin:
i've got an identical setup on another server, which works flawlessly.
as i don't know, where these problems might originate from, i hope that
you can help me!
best regards,
raoul bhatia
