Description Luke Stanton 2021-11-15 21:57:44 UTC 
Description of problem:

Pods which attach PVs are experiencing startup delays as nodes wait to recognize a volume as being attached. This is the case with both dynamic storage classes as well as with pre-defined OCS storage & Ceph. This has been seen on OCP 4.7 clusters as well as Red Hat 4.8 clusters and appears to affect multiple types of storage backends.



How reproducible:

Consistently



Steps to Reproduce:

Deploy a pod that makes use of persistent storage.



Actual results:

Delay is experienced waiting for volume to attach.



Expected results:

Volume would attach a reasonable amount of time.
