Description Gal Zaidman 2021-07-20 08:28:47 UTC

Description of problem:

In Openshift 4.9 we added the csi-resizer.
Currently, the resizer doesn't work in OFFLINE mode due to an implementation based on DiskAttachments and the fact that the NodeStage Cap needs fixing[1].
Once BZ[1] is done we should port to implementation based on Disk objects to support OFFLINE expansion.

Version-Release number of selected component (if applicable):

How to test:
make sure test case:
"External Storage [Driver: csi.ovirt.org] [Testpattern: Dynamic PV (default fs)(allowExpansion)] volume-expand Verify if offline PVC expansion works"
passes

if I create pvc without pod and resize of pvc works, is it enough to check?

> if I create pvc without pod and resize of pvc works, is it enough to check?

yes, also in CSI tests I see this is working so we have a pretty good coverage

Comment 4 michal 2021-08-08 07:26:59 UTC

step to reproduce:
1) Create PVC and don't create any pod 
2) resize storage of PVC
3) Check that size of storage update
actual:
size updated successfully.
