[Rashid Hamid]

Is it possible to extend logical volume and extend file system online without halting the pacakage?
What is the step to do that with onlineJFS and without onlineJFS


Thanks

Hi
Sure if your system installed Online JFS
But may not possible to lvextend and fsextend without halt package.

1. Having Online JFS
lvextend -L /dev/vg/lvolname
fsadm -b M /

2. Non online JFS
you need umount the filesystem you want to increase or decrease lvs
so If the file system is cluster Vg
you have to halt package containing the file sytstem

Even if you have online JFS, you will have to halt the package to extend the FS.

Please read my previos statement as
"Even if you have online JFS, you will have to restart the cluster to make it aware of the new FS size."

Rashid,

You can extend LV and fs if you have online JFS. Without online JFS, you have to halt package, unmount and do lvextend, extendfs commands.
