Hi, 

When we trying create persistent volume for pod its failing with following 
error. 

Failed to provision volume with StorageClass "glusterfs-storage": 
glusterfs: create volume err: error creating volume Server busy. Retry 
operation later.. 

 [root@master ~]# oc get po 
NAME READY STATUS RESTARTS AGE 
glusterblock-storage-provisioner-dc-1-21b9t 1/1 Running 0 18h 
glusterfs-storage-31fjz 1/1 Running 0 90d 
glusterfs-storage-9h5cf 1/1 Running 0 90d 
glusterfs-storage-pnb67 1/1 Running 0 90d 
heketi-storage-1-gkt2h 1/1 Running 0 18h 


We are using storage class as glusterfs-storage (default). and checked all 
(glusterd,gluster-blockd) service running fine in all 3 pod gluster pods. 
we could see followig events from heketi pod 
[heketi] WARNING 2019/01/10 07:58:27 operations in-flight (8) exceeds

8 operations are in flight thats why heketi server busy. can you tell me 
how to restet operations. 
[root@heketi-storage-1-1l6zx /]# heketi-cli server operations info 
Operation Counts: 
Total: 0 
In-Flight: 8 New: 0 
Stale: 0
