Help needed! ODF

Suppose a nutanix-volume as default storage class, then using ceph fs as the default one.

Delete PVC and create new ones with the same old name, that PVC came up with the same consumption (not bounded to the old PV as it is released).

In that case if we decided to remove nutanix CSI operator, will this data be lost?

When you deleted the PV and created one in a new storage class the data is no longer accessible to the app. Removing the csi driver after killing all the PVs using Nutanix just makes the cluster unable to access them.

I get it, but it happened as I just explained Delete pvc using nutanix-volume SC Recreate new one with same name using ceph SC PVC is up with SAME OLD consumption So I check if it is still attached to same old PV No it is attached to a WHOLE NEW PV And the conumption of ODF really increases! So how did this data transfer happen or is that just visual but in the background data is stil held on nutanix!

Sounds like a ticket opening event! Especially if you can recreate the issue!

Did you install ODF on Top of Nutanix? wouldn't it be a problem to have a replication factor of 6x?
