--- Comment #1 from Atin Mukherjee <amukherj at redhat.com> ---
Description of problem:
When glusterd is stopped on one node and performed volume set operation on only
two volumes(one is upgraded and another volume is newly created.). Restarted
glusterd on the node where it stopped on that node seeing "Couldn't find
volinfo" errors and shd and brick process on the two volume where volume option
is set are offline.

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

How reproducible:
1/1

Steps to Reproduce:
1. Create 1000 volumes and start them
2. Performed in-service upgrade on the cluster. 
3. Create 1000 more volumes (1X3 replicate) and start them
4. Stop glusterd on node N1.
5. Perform volume set operation on two volumes from n2
'performance.readdir-ahead on'. One which is being used for upgrade and another
newly created volume. 
6. Start glusterd on node N1.

Actual results:
glusterfsd and shd on these two volumes are offline.
seeing "couldn't find vol info" in glusterd logs. 

Expected results:
glusterfsd and shd should be online and should not see any errors with
"Couldn't find volinfo" in glusterd log.
