You will need to install 'cmirror' package(s),and start cmirror service
on all cluster nodes

# service cmirror start

After that pvmove should work

Here is some docs :

- ->
https://access.redhat.com/knowledge/docs/en-US/Red_Hat_Enterprise_Linux/5/html-single/Logical_Volume_Manager_Administration/index.html#mirvol_create_ex

- -> https://access.redhat.com/knowledge/solutions/279583 ( eventual
error if cmirror is not running ) ...

but as you said, can you open case with GSS and get dedicated resource
for this question

Thank you

Kind regards,
