Re: Serviceguard Extend a Filesystem
vgchange -c n
-->
Control the membership of volume groups in a
high availability cluster.
here n means: Remove each specified volume group from membership in the high availability cluster. The high availability software does not need to be running.
vgchange -a n
-->
Deactivate each specified volume group and its associated logical volumes. You must close the logical volumes prior to executing
this option. For example, if the logical volume contains a file system, the file system must be unmounted.
Thanks.

Re: Serviceguard Extend a Filesystem
I have free space in VG. And I want to extend the file system in primary node which is currently active. This is 2node service guard cluster and onLineJFS also there. so apart from the lvextend and fsadm commands can we need to take care any other cluster related files or map files in both the nodes?
Can we export the map file on primary and import the same map file in alternate node?

Re: Serviceguard Extend a Filesystem
if you are not adding additional disk to the VG , map file export not needed.
If you have free space in the VG, you just need to extend it using lvextend and fsadm command , it is online. Cheers.
