Can you please share the output of
source /etc/ovirt-hosted-engine/hosted-engine.conf
find /rhev/data-center/ -path "*/${sdUUID}/images/${conf_
image_UUID}/${conf_volume_UUID}" -type f -exec sh -c 'sudo -u vdsm dd
if=$1 2>/dev/null | tar -xOvf - vm.conf 2>/dev/null' {} {} \;
executed on your first host?
output for the above command
https://paste.fedoraproject.
org/489159/97176147/
This one looks fine,
now the point is why the OVF_STORE doesn't seams so,
Could you please try executing:
sudo -u vdsm dd if=/rhev/data-center/mnt/glusterSD/10.70.36.79:_engine/
27f054c3-c245-4039-b42a-c28b37043016/images/fdf49778-
9a06-49c6-bf7a-a0f12425911c/8c954add-6bcf-47f8-ac2e-4c85fc3f8699 | tar
-xOvf - 21e0e248-19bf-47b3-b72f-6a3740d9ff43.ovf
Simone, i ran the following steps and i see that vm.conf file is missing.
1) Installed three nodes with glusterfs as storage domains.
2) Configured power management on all the nodes and ran the command
'poweroff -f' on one of the node.
3) Engine tried to fence the host and it logged the message 'Host is
rebooting' but this never came up.
4) After some time i manually powered on the host and once the host is up
i see that Hosted Engine HA : Not active.
5) I see the following error message in broker.log and vm.conf file is
missing.
