Partition size is 33TB and I used jfsutils from CVS to mkfs, since
repository version doesn't support partitions larger then 32T. Also I'm
using entire disk, w/o partition table. Here is jfs_tune output:

# jfs_tune -l /dev/sdb
jfs_tune version 1.1.14, Oct  4 2010

JFS filesystem superblock:

Unfortunately I've upgraded it before I came across this report. Will
update you if the problem recurs.
