Hi all, I'm testing ovirt+glusterfs with only two node for all (engine, glusterfs, hypervisors), on centos 6.5 hosts following guide at: http://community.redhat.com/blog/2013/09/up-and-running-with-ovirt-3-3/ http://www.gluster.org/2013/09/ovirt-3-3-glusterized/ but with some change like setting on glusterfs, parameter cluster.server-quorum-ratio to 50% (due to prevent glusterfs to go down if one node goes done) and option on /etc/glusterfs/glusterd.vol "option base-port 50152" (due to libvirt port conflict). So, with the above parameter I was able to stop/reboot node not used to directly mount glusterfs (eg lovhm002), but when I stop/reboot node, that is used to mount glusterfs (eg node lovhm001), all data center goes done, especially when I stop service glusterfsd (not glusterd service!!!), but the glusterfs still alive and is reachable on node lovhm002 that survives but ovirt/libvirt marks DC/storage in error. Do you have any ideas to configure DC/Cluster on ovirt that remains aware if node used to mount glusterfs goes down? This is a sample vdsmd.log on node that remains on-line (lovhm002) when I stopped services glusterd and glusterfsd node lovhm001: Thread-294::DEBUG::2014-01-05 19:12:32,475::task::1168::TaskManager.Task::(prepare) Task=`a003cde0-a11a-489e-94c2-611f3d096a81`::finished: {'info': {'spm_id': 2, 'master_uuid': '85ad5f7d-3b67-4618-a871-f9ec886020a4', 'name': 'PROD', 'version': '3', 'domains': '85ad5f7d-3b67-4618-a871-f9ec886020a4:Active,6a9b4fa6-f393-4036-bd4e-0bc9dccb1594:Active', 'pool_status': 'connected', 'isoprefix': '/rhev/data-center/mnt/lovhm001.fabber.it:_var_lib_exports_iso/6a9b4fa6-f393-4036-bd4e-0bc9dccb1594/images/11111111-1111-1111-1111-111111111111', 'type': 'GLUSTERFS', 'master_ver': 2, 'lver': 3}, 'dominfo': {'85ad5f7d-3b67-4618-a871-f9ec886020a4': {'status': 'Active', 'diskfree': '374350675968', 'alerts': [], 'version': 3, 'disktotal': '375626137600'}, '6a9b4fa6-f393-4036-bd4e-0bc9dccb1594': {'status': 'Active', 'diskfree': '45249200128', 'alerts': [], 'version': 0, 'disktotal': '51604619264'}}} Thread-294::DEBUG::2014-01-05 19:12:32,476::task::579::TaskManager.Task::(_updateState) Task=`a003cde0-a11a-489e-94c2-611f3d096a81`::moving from state preparing -> state finished Thread-294::DEBUG::2014-01-05 19:12:32,476::resourceManager::939::ResourceManager.Owner::(releaseAll) Owner.releaseAll requests {} resources {'Storage.2eceb484-73e0-464a-965b-69f067918080': < ResourceRef 'Storage.2eceb484-73e0-464a-965b-69f067918080', isValid: 'True' obj: 'None'>} Thread-294::DEBUG::2014-01-05 19:12:32,476::resourceManager::976::ResourceManager.Owner::(cancelAll) Owner.cancelAll requests {} Thread-294::DEBUG::2014-01-05 19:12:32,476::resourceManager::615::ResourceManager::(releaseResource) Trying to release resource 'Storage.2eceb484-73e0-464a-965b-69f067918080' Thread-294::DEBUG::2014-01-05 19:12:32,476::resourceManager::634::ResourceManager::(releaseResource) Released resource 'Storage.2eceb484-73e0-464a-965b-69f067918080' (0 active users) Thread-294::DEBUG::2014-01-05 19:12:32,476::resourceManager::640::ResourceManager::(releaseResource) Resource 'Storage.2eceb484-73e0-464a-965b-69f067918080' is free, finding out if anyone is waiting for it.
