ext3 corruption



hey ext3 gurus - i am desperately looking for some help on a problem where my ext3 filesystem got corrupted my beyond repair

the issue i saw the FS size  was much less the logical volume size  - when we tried to mount it .....so we attempted an fsck - we lost all the data

these are the messages we got before the data corruption happened

the hal.hotplug seems to have triggered something  - the filesystem is on an LVM2 volume with multipathing managing the hba paths to EMC

does this ring a bell with anyone ?
