Description of problem (please be detailed as possible and provide log
snippets):

Create a single namespace with 1 pod using a large PV size(500g/1T/2T/4T) and usage (100g/500g/1.5T/3T) on CephFs.

Using OADP to create CSI snapshot backup for the single namespace. (volumesnapshot & volumesnapshotcontent were created during the backup. volumesnapshot - Delete while backup complete)

While restoring the single namespace using the volumesnapshotcontent, the PVC creates fast and the PV creation takes a long time.

Version of all relevant components (if applicable):

OCP - 4.16.2
ODF - 4.16.2-rhodf

Does this issue impact your ability to continue to work with the product
(please explain in detail what is the user impact)?

Rate from 1 - 5 the complexity of the scenario you performed that caused this
bug (1 - very simple, 5 - very complex)?

Can this issue reproducible?
Yes

Can this issue reproduce from the UI?
maybe

If this is a regression, please provide more details to justify this:

Steps to Reproduce:
1. Using OADP operator to backup and restore
2. Create a single namespace with 1 pod
3. Using OADP - Create CSI snapshot backup
4. Using OADP - Restore from CSI snapshot backup

Actual results:
PV creation (cephFS) takes a long time

Expected results:
PV creation (cephFS) takes a few seconds (like CephRBD)

Additional info:

CephFS vs. CephRBD restore duration:

CephFS CephRBD
PV Size 500G, Usage 100g 0:33:43 0:00:13
PV Size 1000G, Usage 500g 2:44:43 0:00:13
PV Size 2000G, Usage 1500g 8:13:32 0:00:23
PV Size 4000G, Usage 3000g 16:32:42 0:00:23
