I'm new to UML and although I have checked the tutorials, FAQs and this
archive, I can't seem to overcome a strange problem with my root
The UML kernel always mounts them as read-only, most of the time, the ext2fs
check also complains about some inconsistencies.
I'm running a Debian 'sarge' installation with a 2.4.20 kernel (the latest
the Debian pool). My two UML kernels (the one, that pops out of the
user-mode-linux package as well as one compiled by me; both are 2.4.20) show
the same behaviour with the FS images (even the Debian 3.0r0 image
downloaded from the UML website)
'linux ubd0=./Debian.30r0.ext2' e.g. produces the following error:
Checking root file system...
fsck 1.27 (8-Mar-2002)
fsck.ext2: No such file or directory while trying to open /dev/ubd/0
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
fsck failed. Please repair manually and reboot. Please note
that the root file system is currently mounted read-only. To
remount it read-write:
# mount -n -o remount,rw /
CONTROL-D will exit from this shell and REBOOT the system.
Any hints on this? Someone told me to try it with devfs=nomount, this shows
very same error though :(
