   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.
