I'm using a COWed block device as my root filesystem. After boot, I see
this:
Size mismatch (140789027962880 vs 209715200) of COW header vs backing file
Failed to open '/mirror/uml/esperi-root-cow.image', errno = 22
VFS: Cannot open root device "98:0" or unknown-block(98,0)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(98,0)
With 2.6.12.5-bs11, it mounts fine.
There don't seem to be any new userspace utilities since April 2004 (at least
not on sourceforge) --- so it can't be that the COW file format has changed.
This looks more like some sort of byte-ordering problem.
Any ideas? What dumb thing have I done now? (Is it just that I need to let
UML recreate the COW file itself? Are COW files not portable between UMLs
or something?)
