+===========================================
+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 ASCII. The default is to do no conversion.
+
+**iocharset=utf8** Use 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(*)** 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.
+
+**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, 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 a TRIM command to the block device is considered useful.
+When no value is given to the discard option, it defaults to 64 blocks, which means 256KiB in JFS. The minlen value
+of discard overrides the minlen value given on an FITRIM ioctl().
