I'm running a virtual machine on vmware esx. vm = Centos 5.x (redhat)
I'm running ext2 with no LVM.
After removing some vmware "snapshots" the system rebooted into a
readonly file system.
Another reboot and errors and kernel panic etc.
I've rebooted with linux rescue via the cdrom image.
I've mounted the file system in /mnt/sysimage
e2fsck -p -f /mnt/sysimage gives the error about superblock cannot be
e2fsck -b 8193 /mnt/sysimage gives the same error message.
So, am I using the correct command?
How do I find the location of a copy of the superblock?
Still Goooooooogling but any help appreciated.
