Thank you zaxxon and johnf. Really appreaciate that.
It is a crusial system act as a application interface between the cluster. thus, rebooting the system is only can be done when there is a quaterly shechdule downtime. I did manage to free out some space.
As you can see, i do have mirror right? Correct me if i am wrong.
For example:
hd4 jfs 3 6 2 open/syncd /after Increasing of JFS, does the number increase also.?? automatically. or i need to do something??
example hd4 jfs 6 12 2 open/syncd / something like that.
Thank again.

jfs_tune
jfs_tune(8) Set JFS file system parameters. jfs_tune(8)
NAME
jfs_tune - adjust tunable file system parameters on JFS
SYNOPSIS
jfs_tune [options] device
DESCRIPTION
jfs_tune adjusts tunable parameters on a Linux JFS file system or external journal. jfs_tune must be run as root.
device is the special file name corresponding to the actual device (e.g. /dev/hdb1) on which a JFS file system or JFS external journal has
been created.
OPTIONS
-J device=external-journal
Attach the JFS external journal located on external-journal to the JFS file system on device.
The external journal must already have been created using the command. More than one file system may share the same external jour-
nal.
mkfs.jfs -J journal_dev external-journal
Attach the external journal to the file system by using the command
jfs_tune -J device=external-journal device
Instead of specifying a device name directly, external-journal can also be specified by either LABEL=label or UUID=UUID (Use
jfs_tune -l device to display a journal device's volume label and UUID.)
-l List the contents of the JFS file system or external journal superblock that resides on device.
-L volume-label
Set the volume label of the JFS file system or external journal. JFS labels can be at most 16 characters long; if volume-label is
longer than 16 characters, jfs_tune will truncate it and print a warning. The volume label can be used by mount(8), fsck(8), and
/etc/fstab(5) (and possibly others) by specifying LABEL=volume_label instead of a block special device name like /dev/hda5.
-U UUID
Set the universally unique identifier (UUID) of the file system or external journal device to UUID. The format of the UUID is a
series of hex digits separated by hyphens, like this: "c1b9d5a2-f162-11cf-9ece-0020afc76f16". The UUID parameter may also be one of
the following:
clear clear the file system UUID
random generate a new randomly-generated UUID
time generate a new time-based UUID
The UUID may be used by mount(8), fsck(8), and /etc/fstab(5) (and possibly others) by specifying UUID=uuid instead of a block spe-
cial device name like /dev/hda1.
See uuidgen(8) for more information.
-V Print version information and exit (regardless of any other chosen options).
EXAMPLES
Set a randomly-generated UUID for the JFS file system on the 3rd partition of the 2nd hard disk, and view the resultant superblock:
jfs_tune -l -U random /dev/hdb3
Attach an already existing external journal on a device labeled JFSLog to a JFS file system on /dev/hda8:
jfs_tune -J device=LABEL=JFSLog /dev/hda8

Please send as much pertinent information as possible including any error messages resulting from running jfs_tune.
