Description of problem:


Version-Release number of selected component (if applicable): GlusterFS 3.8.4 (latest)

How reproducible: Always


Steps to Reproduce:
1. Run command: "gluster volume set all cluster.enable-shared-storage enable"

Actual results:
1. The running Volume now lists "cluster.enable-shared-storage: enable"
a. The command returned success.
2. However the shared volume was not created.

Expected results:
1. When the command fails, a failure return code is expected.
a. With a relevant description.
2. It is expected that the command will create the shared volume.

Additional info:

OS: Debian Jessie

1. Rebooting did not help.
2. Rebuilding the clustered data volume did not help.
3. Clearing files in /var/run/gluster did not help. 
4. Logs lack error messages except:
   readv on /var/run/gluster/d373e2b2e599fb58e944558312eb1ae5.socket failed (Invalid argument)

Was the hook script /var/lib/glusterd/hooks/1/set/post/S32gluster_enable_shared_storage.sh present at the time this was seen. Hook scripts get deleted when we clean up /var/lib/glusterd, and need to be installed again.

1. At this point I am not able to tell if it was installed.
a. I have long since moved on and installed by other means.
2. Where is this documented about the scripts?
3. If the scripts are missing but needed, the command should fail and specifically state that the scripts are missing.
a. The command should not fail but report success.

I agree, maybe we can edit the summary of this bug to reflect the same, and make the necessary changes so that the command fails with the appropriate message.

Based on comment #3, updating the summary of the bug.

    glusterd/shared storage: Check for hook-script at staging
    
    Check if S32gluster_enable_shared_storage.sh is present
    at /var/lib/glusterd/hooks/1/set/post/ at staging
    before proceeding with the command. Fail the command
    with the appropriate error message in case it is not
    present.
