Issues have been reported when an ext3 file system fills
up to the point where ENOSPC is returned to write
requests for a long period of time, and the file system is subsequently
unmounted. A forced check is initiated (fsck -fy) before the next mount. It appears that the fsck checks might corrupt the file system inode information.
This problem has been seen only on fibre channel
(SAN) storage; it has not been seen with directly attached storage
or NFS storage.
