Hello

I have a question concerning Linear RAID and superblock update time
inconsistency. My server came to a sudden breakdown when the power was lost.
When i tried to start the machine i get the errors pasted below on my Linear
RAID device. What should I do, mkraid --force /dev/mdo, will de data be
intact?

Regards
/Johan
