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..."
Well, of course not, the filesystem is ext3, not ext2.
I also tried fsck.ext3, but the error messages stay the same.
So, how could I fsck these arrays?
Are you using lvm on top of the mdraid?
If so you need to fsck the lvs not the mds.
