1IBM's Journaled File System (JFS) for Linux

5The following mount options are supported:
6
7iocharset=name	Character set to use for converting from Unicode to
8		ASCII.  The default is compiled into the kernel as
9		CONFIG_NLS_DEFAULT.  Use iocharset=utf8 for UTF8
10		translations.  This requires CONFIG_NLS_UTF8 to be set
11		in the kernel .config file.  Specify iocharset=none for
12		no conversion (default linux-2.6 behavior).
13
14resize=value	Resize the volume to <value> blocks.  JFS only supports
15		growing a volume, not shrinking it.  This option is only
16		valid during a remount, when the volume is mounted
17		read-write.  The resize keyword with no value will grow
18		the volume to the full size of the partition.
19
20nointegrity	Do not write to the journal.  The primary use of this option
21		is to allow for higher performance when restoring a volume
22		from backup media.  The integrity of the volume is not
23		guaranteed if the system abnormally abends.
24
25integrity	Default.  Commit metadata changes to the journal.  Use this
26		option to remount a volume where the nointegrity option was
27		previously specified in order to restore normal behavior.
28
29errors=continue		Keep going on a filesystem error.
30errors=remount-ro	Default. Remount the filesystem read-only on an error.
31errors=panic		Panic and halt the machine if an error occurs.
