   5 The following mount options are supported:
   6
   7 iocharset=name  Character set to use for converting from Unicode to
   8                 ASCII.  The default is to do no conversion.  Use
   9                 iocharset=utf8 for UTF8 translations.  This requires
  10                 CONFIG_NLS_UTF8 to be set in the kernel .config file.
  11                 iocharset=none specifies the default behavior explicitly.
  12
  13 resize=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
  19 nointegrity     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
  24 integrity       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
  28 errors=continue         Keep going on a filesystem error.
  29 errors=remount-ro       Default. Remount the filesystem read-only on an error.
  30 errors=panic            Panic and halt the machine if an error occurs.
