PowerScale Replication - Reprotect should NOT be calling allow_write_revert

[santhoshatdell]

Bug Description

Current implementation of reprotect:

1. Initial check: the policy has to be write enabled at the local site.
2. If the remote site has policy enabled (unplanned failover), disable the policy.
3. Verify that a SyncIQ policy exists on the local, and create one if it does not.
4. Enable the policy on the local.
5. Disallow write on remote (allow_write_revert).

As being discussed in 518(#518), allow_write_revert action on the remote policy (step-5) will delete the directory and gets recreated by the source's SynIQ policy.
This is not the right step to be performed and needs to be investigated. Further, there will be issues with existing NFS export due to recreation.

Logs

POST /platform/11/sync/jobs/ {"action":"allow_write_revert","id":"csi-default--Five_Minutes"}

This request to the API is what causes a deletion of the data before it gets recreated.

Steps to Reproduce

• Install driver with replication enabled,
• Provision volume to Pod using the storage class with replication enabled,
• Use repctl to initiate failover at the target k8s cluster.
• Then run reprotect to make the target as new source.

Expected Behavior

Reprotect should not be calling allow_write_revert and should be executing the right steps in the right order.

The reprotect functionality is currently not supported for PowerScale. The implementation that was calling the "allow_write_revert" operation is removed. We will be reimplementing the reprotect functionality as a enhancement.
