Hi Abu,

No Downtime required .You have to create the LV in the same VG and mount it manually in the mount Point.

You need to put the filesystem entries in the cluster configuration file in both nodes. Export the VG in Preview mode on  primary node and import in the seconday node. For testing , you may activate the VG in read only mode (Secondary node) and test it by mounting also  .

Correction to "You need to put the filesystem entries in the cluster configuration file in both nodes."

You need to put the filesystem entries in the package configuration file in both nodes (legacy-style package) or the modular package configuration file used to create/update the package.

Also, don't forget to export/reimport the volume group on the node where the LVOL was NOT created, so that /dev/<vgname>/<newlvol> will be created, or do it yourself manually.
