12 The following mount options are supported:
14 iocharset=name Character set to use for converting from Unicode to
15 ASCII. The default is compiled into the kernel as
16 CONFIG_NLS_DEFAULT. Use iocharset=utf8 for UTF8
17 translations. This requires CONFIG_NLS_UTF8 to be set
18 in the kernel .config file.
20 resize=value Resize the volume to <value> blocks. JFS only supports
21 growing a volume, not shrinking it. This option is only
22 valid during a remount, when the volume is mounted
23 read-write. The resize keyword with no value will grow
24 the volume to the full size of the partition.
28 Plans for our near term development items
30 - enhance support for logfile on dedicated partition
31 - get access control list functionality operational
32 - get extended attributes functionality operational
34 Longer term work items
36 - implement defrag utility, for online defragmenting
