Ye, Online JFS is used to extend the FS even when the FS is mounted.

#lvextend â L (Present Space + New space) /dev/vg00/lvol4

If OnlineJFS is avaible please carry the next step.
#fsadm â F vxfs â b (Present Space + New Space X 1024) /mount_point

If OnlineJFS is not there not there then

Umount the file System
Then Do
#umount /mount_point
#lvextend â L (Present Space + New Space) /dev/vg00/lvol4
#extendfs -F vxfs /dev/vg00/rlvol
Then Do Mount
#mount /dev/vg00/lvol /mount_point

All the best..

You have to use ignite for extending / file system also.

That means its not possible to Extend the Root (/) FS online using OnlineJFS ???

Am i Right??

[Muthukumar_5]

Yes. you have to use ignite-ux for /root fs extend operation.

Since the root file system has to be contiguous, it cannot be extended with or without online JFS. Any other file system can be extended by utilizing non-contiguous free space on the root volume but not /.

Hi ,

Yes , It is possible to extend the / file system with the help of online jfs.But you have to make the pv free in contiginous manner.
For that first you have to move the pv of lool4 to other physical location. then you can extend the size of / file system with fsadm command.

Hi GS,

It is possible to extend root (/) file system using OnlineJFS. Just check the url below (docID : KBRC00006582) about 'Extending the root file system with Online JFS - fsadm' :

Hope this information can help you.

If you have OnLineJFS, it is easiest to extend the file system by just using 'sam', particularly if you have X-windows software so you can run the GUI.

There is a way - online - if root is lvol3, and lvol4 is /home - then you can create a new /home - move the current home to the new one, then un mount original /home, mount new home to /home, lvremove /dev/vg00/lvol4, then extend /

Course - ignite is the preferered way - but requires downtime.
