IBM's Journaled File System (JFS) for Linux

JFS Homepage:  http://jfs.sourceforge.net/

The following mount options are supported:

iocharset=name  Character set to use for converting from Unicode to
                ASCII.  The default is to do no conversion.  Use
                iocharset=utf8 for UTF-8 translations.  This requires
                CONFIG_NLS_UTF8 to be set in the kernel .config file.
                iocharset=none specifies the default behavior explicitly.

resize=value    Resize the volume to <value> blocks.  JFS only supports
                growing a volume, not shrinking it.  This option is only
                valid during a remount, when the volume is mounted
                read-write.  The resize keyword with no value will grow
                the volume to the full size of the partition.

nointegrity     Do not write to the journal.  The primary use of this option
                is to allow for higher performance when restoring a volume
                from backup media.  The integrity of the volume is not
                guaranteed if the system abnormally abends.

integrity       Default.  Commit metadata changes to the journal.  Use this
                option to remount a volume where the nointegrity option was
                previously specified in order to restore normal behavior.

errors=continue         Keep going on a filesystem error.
errors=remount-ro       Default. Remount the filesystem read-only on an error.
errors=panic            Panic and halt the machine if an error occurs.

uid=value       Override on-disk uid with specified value
gid=value       Override on-disk gid with specified value
umask=value     Override on-disk umask with specified octal value.  For
                directories, the execute bit will be set if the corresponding
                read bit is set.
