Dear oVirt,
While working on a procedure to get the NFS v4 mount from Netapp, working on
oVIrt, following steps came out to be the way to go in regards of setting it up
for oVIrt SHE and VM Guests:
* mkdir /mnt/rhevstore
* mount -t nfs 10.20.30.40:/ovirt_hosted_engine /mnt/rhevstore
* chown -R 36.36 /mnt/rhevstore
* chmod -R 755 /mnt/rhevstore
* umount /mnt/rhevstore
This works fine, and it needs to be executed on each Hypervisor, before its
provisioned into oVirt.
However, just today I have discovered that command chmod -R 755 /mnt/rhevstore,
if executed on new to be added Hypervisor, after oVirt is already running, it
brings the oVirt Engine into broken state.
The moment I executed the above on 3rd Hypervisor, before provisioning it into
oVirt, following occurred:
* Engine threw following error:
* 2019-08-19 13:16:31,425Z ERROR
[org.ovirt.engine.core.vdsbroker.vdsbroker.SpmStatusVDSCommand]

method
* Connection was lost:
* packet_write_wait: Connection to 10.210.11.10 port 22: Broken pipe
* And VDSM on SHE Hosting hypervisor started logging errors like:

I am unable to boot the Engine VM – it end up in Status ForceStop
Hosted-engine –vm-status shows:
[root@ovirt-sj-02 ~]# hosted-engine --vm-status
The hosted engine configuration has not been retrieved from shared storage.
Please ensure that ovirt-ha-agent is running and the storage server is
reachable.
But, storage is mounted and reachable, as well as ovirt-ha-agent running:
[root@ovirt-sj-02 ~]# systemctl status ovirt-ha-agent

Can somebody help me with what to do?
