Hello, I have an issue probably related to my particular implementation but I
think some controls are missing
Here is the story.
I have a cluster of two nodes 4.4.10.3 with an upgraded kernel as the cpu
(Ryzen 5) suffer from an incompatibility issue with the kernel provided by
4.4.10.x series.
On each node there are three glusterfs "partitions" in replica mode, one for
the hosted_engine, the other two are for user usage.
The third node was an old i3 workstation only used to provide the arbiter
partition to the glusterfs cluster.
I installed a new server (ryzen processor) with 4.5.0 and successfully
installed glusterfs 10.1 and inserted the arbiter bricks implemented on
glusterfs 10.1 while the replica bricks are 8.6 after removing the old i3
provided bricks.
I successfully imported the new node in the ovirt engine (after updating the
engine to 4.5)
The problem is that the ovirt-ha-broker doesn't start complaining that is not
possible to connect the storage. (I suppose the hosted_engine storage) so I did
some digs that I'm going to show here:
####
1. The node seem to be correctly configured:
[root@ovirt-node3 devices]# vdsm-tool validate-config
SUCCESS: ssl configured to true. No conflicts
[root@ovirt-node3 devices]# vdsm-tool configure
Checking configuration status...
libvirt is already configured for vdsm
SUCCESS: ssl configured to true. No conflicts
sanlock is configured for vdsm
Managed volume database is already configured
lvm is configured for vdsm
Current revision of multipath.conf detected, preserving
Running configure...
Done configuring modules to VDSM.
[root@ovirt-node3 devices]# vdsm-tool validate-config
SUCCESS: ssl configured to true. No conflicts
####
2. the node refuses to mount via hosted-engine (same error in broker.log)
[root@ovirt-node3 devices]# hosted-engine --connect-storage
Traceback (most recent call last):
File "/usr/lib64/python3.6/runpy.py", line 193, in _run_module_as_main

#####
3. manually mount of glusterfs work correctly
[root@ovirt-node3 devices]# grep storage
/etc/ovirt-hosted-engine/hosted-engine.conf
storage=ovirt-node2.ovirt:/gveng
# The following are used only for iSCSI storage
[root@ovirt-node3 devices]#
[root@ovirt-node3 devices]# mount -t glusterfs ovirt-node2.ovirt:/gveng
/mnt/tmp/
[root@ovirt-node3 devices]# ls -l /mnt/tmp
total 0
drwxr-xr-x. 6 vdsm kvm 64 Dec 15 19:04 7b8f1cc9-e3de-401f-b97f-8c281ca30482
What else should I control? Thank you and sorry for the long message
Diego
