file system extension on exclusively shared volume group

[CCIL]

Hi
I hv service guard with OPS edition , one of the Package uses an exclusively shared volume group (vg02) which is of size 30 GB , currently 20 GB is been used by two logical volumes , with file system vxfs , if i want to extend one of the logical volume , whether i would require to stop the cluster package who access the volume group (vg02) . the OS version is 11i

Hi,

if you only want to change the size of the lvol and you have Online JFS installed you can increase the size of the lvol and the filesystem online.

There should be no additional steps required since these changes are only done in the LVM structures which are on disk. But you need Online JFS to do this without umounting the filesystem.

Regards,

Jochen

how do i check whether i have online JFS ?

[Armin Feller]

# swlist -l fileset | grep -i online

or
# vxlicense -p

Check your swlist output for Advanced VxFS:

$ swlist -l product | grep -i advanced
AdvJournalFS B.11.00 The Advanced VxFS File System

Hi,

You can do this online if you have online jfs.

fsadm -F vxfs -b no_of_MB*1024 /filesystem

Kind regards,

Robert-Jan.

[Rainer von Bongartz]

swlist -l product | grep JFS

Should report:

JFS 3.3 JFS 3.3 base filesystem

OnlineJFS 3.3 JFS 3.3 online (Advanced) filesystem features

Hello.

Use Online JFS. fsadm will to the trick for you.
If you do not have online jfs, well it depends if the application configured in package is using volume you want to extend at that time.
If not - you can play with extendfs. Also check your HA policy to determine what event is monitored by MC/SG, so it will not failover if you umount a FS. You are not required to stop the package in most of the cases.

Hope this helps,
