Steps to Reproduce:
1.Run must gather command
$ oc adm must-gather --image=quay.io/rhceph-dev/ocs-must-gather:latest-4.8


2.Check where must-gather pod running: [parallel to step 1]
$ oc get pods -o wide| grep mus
must-gather-n4vxn-helper                                          1/1     Running     0          10s    10.129.2.125   compute-2   <none>           <none>


3.Restart node where must-gather pod running [parallel to step 1]
$ oc get node compute-2
NAME        STATUS     ROLES    AGE     VERSION
compute-2   NotReady   worker   3d16h   v1.21.0-rc.0+120883f
$ oc get node compute-2
NAME        STATUS   ROLES    AGE     VERSION
compute-2   Ready    worker   3d16h   v1.21.0-rc.0+120883f


4.Verify must-gather directory content.
Ceph files do not exist [Fail!!]

**The must-gahter directory includes these files when collect must-gahter without restart node


Actual results:
Ceph files do not exist

Expected results:
The must-gahter directory includes these files when collect must-gahter without restart node
