I got an IBM x3550 M3 server, with 6x 300GB SAS HDD installed, running in RAID10. Ubuntu 10.04.3 LTS is installed. For RAID card, I'm using ServeRAID M5014.
If a HDD is replaced, how can I know the RAID rebuild status?
i forgot if it's working or not on your case, but i ever use it (using different raid card). use MegaCLI util to show your raid status http://www-947.ibm.com/support/entry/portal/docdisplay?lndocid=MIGR-5073015
