I have a 3ware controller that has a RAID 1 of two SATA disks.
After an outage, the linux box (which is running ubuntu), restarted and the partition is now mounted read only. I only have the "/" mount point (this is a test server).
Now, if I go to the 3ware controller by pressing ALT-3 while booting, I don't see any indication that there is something wrong with the disks.
If I let the computer boot, I'm asked by fdisk if I want to fix/ignore/etc the inconsistencies found.
How can I tell what is exactly my problem? I read that somewhere that linux is recognizing that the raid is degraded so it mounted it read only. But I don't know how to find if this is the case.
Thanks for any help.
