rbd: default nouuid if the formattype is xfs

Madhu-1 · humblec · commit f4d6e31764de · 2020-05-05T12:51:56.000+05:30
The problem happens when multiple PVCs with the same UUID are attached/mounted on a node. This can happen after creating a PVC from a snapshot, or cloning a PVC. make nouuid as the default mount option if the format type is xfs to avoid mounting issues. updates: #966 Signed-off-by: Madhu Rajanna <madhupr007@gmail.com> (cherry picked from commit 22a86c5)
