Hello,
when looking into engine.log, I can see, that "gluster probe" returned
errno 107. But I can't figure out why:
2015-01-29 10:40:03,546 ERROR
[org.ovirt.engine.core.bll.InitVdsOnUpCommand]
(DefaultQuartzScheduler_Worker-59) [5977aac5] Could not peer probe the
gluster server node-03. Error: VdcBLLException: org.ovirt.eng
ine.core.vdsbroker.vdsbroker.VDSErrorException: VDSGenericException:
VDSErrorException: Failed to AddGlusterServerVDS, error = Add host failed
error: Probe returned with unknown errno 107
Just for the record: We use the /etc/hosts method because of missing
possibility to choose the network interface for Gluster. The three
Gluster peer hosts have modified /etc/hosts files with addresses binded
to a different interface than the ovirtmgmt addresses.
Example:
root@node-03:~ $ cat /etc/hosts
192.168.200.195 node-01
192.168.200.196 node-02
192.168.200.198 node-03
The /etc/hosts file on engine host isn't modified.

Hello,
we have a strange behavior within an oVirt cluster. Version is 3.5.1,
engine is running on EL6 machine and hosts are using EL7 as operating
system. The cluster uses a GlusterFS backed storage domain amongst
others. Three of four hosts are peers in the Gluster cluster (3 bricks,
3 replica).
When all hosts are restarted (maybe due to power outage), engine can't
activate them again, because Gluster probe fails. The message given in
UI is:
"Gluster command [gluster peer node-03] failed on server node-03."
Checking Gluster peer and volume status on each host confirms that
Gluster peers are known to each other and volume is up.
node-03:~ $ gluster peer status
Number of Peers: 2
Hostname: node-02
Uuid: 3fc36f55-d3a2-4efc-b2f0-31f83ed709d9

Hostname: node-01
Uuid: 18027b35-971b-4b21-bb3d-df252b4dd525
State: Peer in Cluster (Connected)
node-03:~ $ gluster volume status

There are no active volume tasks
Storage domain in oVirt UI is fine (active and green) and usable. But
neither Gluster volume nor any brick is visible in UI.
If I try the command which is shown in UI it returns:
root@node-03:~ $ gluster peer probe node-03
peer probe: success. Probe on localhost not needed
root@node-03:~ $ gluster --mode=script peer probe node-03 --xml
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<cliOutput>
<opRet>0</opRet>
<opErrno>1</opErrno>
<opErrstr>(null)</opErrstr>
<output>Probe on localhost not needed</output>
</cliOutput>
Is this maybe just an engine side parsing error?
