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.

Sorry, didn't have a look in here for some time.
You can see if you have a mirror if you do a "lsvg -l <insertvgnamehere>".

Example:

Code:
root@blabla:/usr/local/doc> lsvg -l rootvg
rootvg:
LV NAME             TYPE       LPs   PPs   PVs  LV STATE      MOUNT POINT
hd5                 boot       1     2     2    closed/syncd  N/A
hd6                 paging     64    128   2    open/syncd    N/A
hd8                 jfs2log    1     2     2    open/syncd    N/A
hd4                 jfs2       2     4     2    open/syncd    /
hd2                 jfs2       25    50    2    open/syncd    /usr
hd9var              jfs2       4     8     2    open/syncd    /var
hd3                 jfs2       4     8     2    open/syncd    /tmp
hd1                 jfs2       2     4     2    open/syncd    /home
hd10opt             jfs2       4     8     2    open/syncd    /opt
lg_dumplv           sysdump    32    32    1    open/syncd    N/A
loglv00             jfslog     1     2     2    open/syncd    N/A
lv00                jfs        2     4     2    open/syncd    /var/adm/csd
lvrepos             jfs2       10    20    2    open/syncd    /repos
paging00            paging     64    128   2    open/syncd    N/A
lg_dumplv2          sysdump    32    32    1    open/syncd    N/A

When a LV is mirrored you have at least twice the number of PP than LPs. In the example above you can see, that all LVs are mirrored but the 2 sysdump devices lg_dumplv and lg_dumplv2.
Increasing a filesystem by blocks, megabytes or something will at least always allocate up to the full size of the next PP. So if you are at the "border" to the next PP and tell the system you need 200 MB more space in the FS, and have 100 MB left in the current PP, it will use it up and get the next full PP too. Let's say you have a size of 256 MB per PP, it would allocate 100 MB of the current PP and all 256 MB of the next PP. Your FS would be larger by 356 MB instead of only 200 MB. You will see more LPs & PPs allocated and if it is a mirrored LV, you will see even more PPs Smilie

But this is nothing to worry about - this is normal.
