IBM's Journaled File System (JFS) for Linux

===========================================



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



The following mount options are supported:



(*) == default



iocharset=name	Character set to use for converting from Unicode to

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

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

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(*)	Commit metadata changes to the journal.  Use this option to

integrity(*)

                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(*)	Remount the filesystem read-only on an error.

errors=panic		Panic and halt the machine if an error occurs.

errors=continue

                        Keep going on a filesystem error.

errors=remount-ro(*)

                        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

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.



discard=minlen	This enables/disables the use of discard/TRIM commands.

discard		The discard/TRIM commands are sent to the underlying

nodiscard(*)	block device when blocks are freed. This is useful for SSD

discard=minlen, discard/nodiscard(*)

                This enables/disables the use of discard/TRIM commands.

		The discard/TRIM commands are sent to the underlying

                block device when blocks are freed. This is useful for SSD

                devices and sparse/thinly-provisioned LUNs.  The FITRIM ioctl

		command is also available together with the nodiscard option.

		The value of minlen specifies the minimum blockcount, when
