Did one of the disks cause the USB reset message?  It appears to
coincide with the start of the trouble, but it may be just that,
coincidence.

Mar  2 01:06:02 quassel kernel: md: using 128k window, over a total of
488383936 blocks.
Mar  2 09:03:43 quassel kernel: usb 4-5.3.2: reset high speed USB
device using ehci_hcd and address 8
Mar  2 09:25:15 quassel kernel: EXT3-fs error (device dm-0):
htree_dirblock_to_tree: bad entry in directory #57262081: directory
entry across blocks - offset=0, inode=2917738116, rec_len=11736,
name_len=107
Mar  2 10:30:46 quassel kernel: md: md0: data-check done.

The output of something like 'ls -l /sys/block/sdb/device' should tell.

Have you run this operation on a kernel version prior to 2.6.24.3? If
so, which version?
