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 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.
