Something seems to be wrong with my file systems, and I want to fsck everything. But I cannot.
The setup consists of 2 hds, carrying 3 raid1 (ext3) file systems (boot, /, swap). OS is up-to-date CentOS 5.
So I boot from CentOS 5.3 dvd in rescue mode, do not mount the file systems, and try to run fsck -y /dev/md0 fsck -y /dev/md1 fsck -y /dev/md2
For each try I get an error message: "Superblock could not be found..." "The device does not seem to contain a valid ext2 filesystem..."
ext2 is the base of the journaling ext3 FS.
I would suggest you use TestDisk http://www.cgsecurity.org/wiki/TestDisk and see if you can recover your filesystem. The tool is powerful. I have been able to recover disk partitions and the filesystems within when all other tools reported "no disk partition" on the HDD.
Good luck. -- Arun Khan
