Extend volume in VCS

You haven't mentioned which version (eg: 5.0? 5.1?) or platform (AIX? Solaris? HP-UX) - here is the Solaris 5.0MP3 manpage - if your version/platform is different, see the manual pages for the relevant version at https://vos.symantec.com/documents

http://sfdoccentral.symantec.com/sf/5.0MP3/solaris/manpages/vxvm/man1m/vxresize.html

fyi: also deleted duplicate comment in unrelated thread since you've already posted a separate discussion thread here.

Below is on assumption that you are using 5.0 and above version.

1. freeze cluster service group which own the filesystem.

# hagrp -freeze <service group> -persistent

2. Verify filesystem size

# df -h

3. Verify from volume manager

# vxprint -qhtg <diskgroup> <volumename>

4.  If you have added disk in diskgroup already, Resize using vxresize which will exten volume as well as filesystem.

# vxresize -g <diskgroup> <volumename> <newsize>                  ------ filesystem should be mounted.
e.g vxresize -g testdg vol01 100g

where 100g is 100gb a new size of filesystem.

5. Verify from df -h and vxprint for new size.

Thanks Anoop
Should not we do anything on other nodes.Should I just follow your steps in the node where the diskgroup is now online

It is a normal filesystem.
Thanks for your help here
