Just an update on this. i solved it myself.
the solution was the mount options used by oVirt.
in ovirt to mount a gpfs remote filesystem use these options :
Path:
/<filesystem path>
VFS Type:
gpfs
Mount Options:
rw,dev=<cluster name fqdn>:<filesystem name>,ldev=<filesystem name>
not entirely sure it the filesystem name has to be the exact same as it is in the owning
cluster as we have the option to rename it in the remote cluster. my filesystem is named
the same in both ends so anyone needing to do this have to do their own tests.
in terms of the filesystem options when granting the remote cluster access, no additional
mount options than RW is needed so default is ok.
remember to chown 36:36 /<filesystem path> before mounting in oVirt.
