Known issue with backup/restore of workloads with multiple UID/GID per volume

[kaovilai]

Currently the backube/volsync mover pods accepts one securityContext per volume.

If a volume contain files with multiple UID/GID owners it may not be possible to restore it back to the same state with current volsync architecture.

Suggested workaround:

• Refrain workloads from using more than one UID/GID per volumeMounts.
• Setting privileged-movers annotation on openshift-adp namespace might work.

  oc annotate --overwrite namespace/openshift-adp volsync.backube/privileged-movers='true'
