From 969299558f10f8ac1fcbcd5a71beff251a5511fd Mon Sep 17 00:00:00 2001 From: rakshith-r Date: Wed, 9 Aug 2023 16:46:45 +0530 Subject: [PATCH] cephfs: set Pool parameter to empty for Snapshot-backed volumes Set VolumeOptions.Pool parameter to empty for Snapshot-backed volumes. This Pool parameter is optional and only used as 'pool-layout' parameter during subvolume and subvolume clone create request in cephcsi and not used for Snapshot-backed volume at all. It is not saved anywhere for use in subsequent operations after create too. Therefore, We can set it to empty and not error out.
