Don't think it's an error, all my clean, mountable JFS volumes do that
(for different values of nTxBlock etc).

Typically, if JFS refuses to mount, it's because it was not cleanly

From a live CD, run fsck (fsck.jfs) on the volumes and see if they
mount. That works for me when I neglect to umount a removable JFS
volume prior to physically removing it.
