Strange Fedora Booting problem: cannotmount 'LABEL=*' partitions

Hi,

 Thanks for suggestions from all helpful friends.

 Just figure out the problem at 2am yesterday night, Very glad!

 After compiling and debugging fsck, which calls blkid* functions, I realized that the partitions images are created on a SATA host, so then when the images are cloned to a PATA hosts, the /etc/blkid.tab should be cleared off, otherwise the first fsck on the first entry with "LABEL=*"  in the /etc/blkid.tab will fail. Second run of fsck reports OK since the new local hard disk partitions|labels are populated into the file /etc/blkid.tab during the first run. That's why.

So the solution is quite straight forward, after clone the system images, run command "cat /dev/null > /etc/blkid.tab", and it is fixed at once.

Thanks again for help. This mail list is really useful.

Hi,

 The file system is clean and un-mounted, but fsck still reports problem.
Any ideas? Thanks.

To me the problem is not a mount problem at all. The error is a failure
running fsck and _not_ mount. I fear your filesystem is bad on hda10.

Being in single user mode, running fsck.ext3, will that succeed or give
you a signal 11 error too?
