We had to reboot the system last night, and on restart fsck failed for the RAID device with the error message: Block bitmap for group 256 is not in group followed by /dev/rd/c0d2p1: Unexpected inconsistency, run fsck manually Running fsck manually produced the error message: e2fsck: bad magic number in superblock while trying to open /dev/rd/c0d2p1 Trying again using e2fsck -B and varying block sizes of 1024, 2048, etc got: Group descriptor look bad... trying backup blocks e2fsck: bad magic number in superblock while trying to open /dev/rd/c0d2p1 However, the DAC controller's consistency check completed at 100% with no errors, and the driver reported no problems during boot. Is there anything that can be done to solve this and save the filesystem? Thanks, David To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
