Tried some manual edits to SD states in the dbase. The net result was I was able to get a node active. However as reconstructing the master storage domain kicked in it was unable to do so. It was also not able to recognize the other SD with similar failure modes to the unrecognized master above. Guessing the newer VDSM version borked things pretty good. So being as this is a test harness and the SD data is not worth saving I just smoked the all SD. I ran engine-cleanup and started from fresh and all is well now.

This test harness setup here consists of two servers tied to NFS storage via IB (NFS mounts are via IPoIB, NFS over RDMA is disabled) . All storage domains are NFS. The issue does occur with both servers on when attempting to bring them out of maintenance mode with the end result being non-operational due to storage attach fail.

The current issue is now that with a working older commit the master storage domain is "stuck" in state "locked" and I see the secondary issue wherein VDSM cannot seem to find or contact the master storage domain even though it is there. I am can mount the master storage domain manually and and all content appears to be accounted for accordingly on either host.

Here is the current contents of the master storage domain metadata:

So now with the older working commit I now get this the "StoragePoolMasterNotFound: Cannot find master domain" error (prior details above when I worked backwards to that commit)

This is odd as the nodes can definitely reach the master storage domain:

showmount from one of the el6.3 nodes:

Interesting.. it might be related to this commit and we're trying to reproduce it.

Did you try to remove that code and run again? does it work without the additional of zombieReaper?
does the connectivity to the storage work well? when you run 'ls' on the mounted folder you get see the files without a long delay ? it might related to too long timeout when validating access to this mount..
we work on that.. any additional info can help

Thanks.

VDSM was built from:
commit 166138e37e75767b32227746bb671b1dab9cdd5e

Attached is the full vdsm log

I should also note that from engine perspective it sees the master
storage domain as locked and the others as unknown.

Causes VDSM to fail to attach storage

I doubt that this is the cause of the failure, as vdsm has always
reported "0" for ib devices, and still is.
it happens only when you call to getCapabilities.. so it doesn't related to the flow, and it can't effect the storage.
Dan: I guess this is not the issue but why is the IOError?

Does a former version works with your Engine?
Could you share more of your vdsm.log? I suppose the culprit lies in one
one of the storage-related commands, not in statistics retrieval.

Since "latest master" is an unstable reference by definition, I'm sure
that History would thank you if you post the exact version (git hash?)
of the code.
