IBM's Journaled File System (JFS) for Linux
JFS Homepage:
The following mount options are supported:
iocharset=name Character set to use for converting from Unicode to
ASCII. 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
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
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 Default. 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 Default. 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. For
directories, the execute bit will be set if the corresponding
read bit is set.
