5The following mount options are supported:
6
7iocharset=name Character set to use for converting from Unicode to
8        ASCII. The default is to do no conversion. Use
9        iocharset=utf8 for UTF-8 translations. This requires
10        CONFIG_NLS_UTF8 to be set in the kernel .config file.
11        iocharset=none specifies the default behavior explicitly.
12
13resize=value Resize the volume to <value> blocks. JFS only supports
14        growing a volume, not shrinking it. This option is only
15        valid during a remount, when the volume is mounted
16        read-write. The resize keyword with no value will grow
17        the volume to the full size of the partition.
18
19nointegrity Do not write to the journal. The primary use of this option
20        is to allow for higher performance when restoring a volume
21        from backup media. The integrity of the volume is not
22        guaranteed if the system abnormally abends.
23
24integrity Default. Commit metadata changes to the journal. Use this
25        option to remount a volume where the nointegrity option was
26        previously specified in order to restore normal behavior.
27
28errors=continue Keep going on a filesystem error.
29errors=remount-ro Default. Remount the filesystem read-only on an error.
30errors=panic Panic and halt the machine if an error occurs.
31
32uid=value Override on-disk uid with specified value
33gid=value Override on-disk gid with specified value
34umask=value Override on-disk umask with specified octal value. For
35        directories, the execute bit will be set if the corresponding
36        read bit is set.
