12 The following mount options are supported:
14 iocharset=name Character set to use for converting from Unicode to
15 ASCII. The default is to do no conversion. Use
16 iocharset=utf8 for UTF8 translations. This requires
17 CONFIG_NLS_UTF8 to be set in the kernel .config file.
19 resize=value Resize the volume to <value> blocks. JFS only supports
20 growing a volume, not shrinking it. This option is only
21 valid during a remount, when the volume is mounted
22 read-write. The resize keyword with no value will grow
23 the volume to the full size of the partition.
25 nointegrity Do not write to the journal. The primary use of this option
26 is to allow for higher performance when restoring a volume
27 from backup media. The integrity of the volume is not
28 guaranteed if the system abnormally abends.
30 integrity Default. Commit metadata changes to the journal. Use this
31 option to remount a volume where the nointegrity option was
32 previously specified in order to restore normal behavior.
34 errors=continue Keep going on a filesystem error.
35 errors=remount-ro Default. Remount the filesystem read-only on an error.
36 errors=panic Panic and halt the machine if an error occurs.
