Description of problem:
We have a virt cluster that gluster service is enable on it (configured manually on DB). When trying to connect second host to storage server it fails with:
AttributeError: 'FileLikeLogger' object has no attribute 'flush'


Version-Release number of selected component (if applicable):
vdsm-gluster-4.10.2-23.0.1.el6rhs.noarch
vdsm-4.10.2-23.0.1.el6rhs.x86_64


How reproducible:
100%

Steps to Reproduce:
Have a virt cluster with connected block pool
- on vds_groups change:
psql -U postgres engine -c "UPDATE vds_groups SET gluster_service = 't' where name = 'cluster_name'";
so the cluster will support gluster service also
- make sure the hosts contains vdsm-gluster package and that gluster service is running
- create new volume from one of the host bricks (need to have a file system on the brick path on the host) (on volumes tab on UI)
- add a second host to the cluster

Actual results:
Cannot add a second host to the cluster, vdsm fails in connectStorageServer:

  File "/usr/lib64/python2.6/multiprocessing/managers.py", line 740, in _callmethod
    raise convert_to_error(kind, result)
AttributeError: 'FileLikeLogger' object has no attribute 'flush'


Expected results:
It should be possible to add more than one host to gluster-virt cluster

This configuration is not currently supported for RHEVM (see RFE in bug 996870).
Until we decide to tackle this RFE, there is no point in addressing this bug (actually, this bug probably blocks this RFE)
Comment 4 Ayal Baron 2014-01-09 18:25:31 UTC 
Should be covered anyway in basic testing of bug 996870 so closing as dup.
