I dunno where you got your fstab, but you still have some inconsistencies.  /dev/pts /dev/shm /proc don't really have backing devices, so their backing devices should be none.

Do a `dumpe2fs -h` on your loopback and on /dev/sda1.  Try disabling some ext3 features for e2fsck 1.35.  Also how did you make the filesystem on this VBD?

Keep in mind we haven't tested OpenSSI on FC4, so you're really experimenting here.  I assume this e2fsck you are running in domU is from FC3, so it is meant to compliment mke2fs from FC3 - not FC4.  It shouldn't be a big problem anyway.

Just /dev/sda1 will be fine.

Thanks for the assistance Roger. I changed the fstab to /dev/sda1, but the
result is the same. The original "sda" device (which is actually a file-backed
VBD for the domU) was created on FC4 using e2fsck ver. 1.38. Could this be the
problem? When I "fsck" it on FC4 it checks fine.
