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
Alexey Dobriyan4de151d2006-03-22 00:13:35 +01009 iocharset=utf8 for UTF-8 translations. This requires
Linus Torvalds1da177e2005-04-16 15:20:36 -070010 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.
