Hi Navin

Can't resize a volume while it is mounted / Active if OnlineJFS is not installed.

Need to unmount the filesystem and increase the size by "vxresize" command.

Thanks & Regards

Ramesh

Hi Navin

To find OnlineJFs installed

# swlist -l product | grep -i jfs

If onlineJFS is installed, it will show you something like

JFS B.11.23 The Base VxFS File System
OnlineJFS B.11.23.0512 Online features of the VxFS File System
PHKL_34179 1.0 JFS3.5 DIO performance; extent rollback

In your case, Base Vxfs fileystem is not OnlineJFS.

Thanks & Regards

Hi Navin

Need to unmount the filesystem and increase the size by "vxresize" command.

It will increase the size of volume and fileystem. No need to run "fsadm".

Thanks & Regards
