Hello,
I'm testing the single node HCI with ovirt-node-ng 4.3.9 iso.
Very nice and many improvements over the last time I tried it. Good!
I have a doubt related to shutdown procedure of the server.
Here below my steps:
- Shutdown all VMs (except engine)
- Put into maintenance data and vmstore domains
- Enable Global HA Maintenance
- Shutdown engine
- Shutdown hypervisor
It seems that the last step doesn't end and I had to brutally power off the
hypervisor.
Here the screenshot regarding infinite failure in unmounting
/gluster_bricks/engine
https://drive.google.com/file/d/1ee0HG21XmYVA0t7LYo5hcFx1iLxZdZ-E/view?us...
What would be the right step to do before the final shutdown of hypervisor?
Thanks,
Gianluca

You can kill gluster via:
/usr/share/glusterfs/scripts/stop-all-gluster-processes.sh
Of course, you can create a systemd service to do that on power off

I will try, thanks Strahil.
BTW: I found similar question on Gluster mailing list and the same script
was referred...
But why has not been yet integrated this kind of flow? It should be quite
normal to integrate shutdown of gluster processes when you shutdown the
server....

I think the missing part here is stopping the SPM (if running on this

from storage.
Both are done when you put a host to maintenance, but in hosted engine
environment this
is not possible from engine since engine runs on the storage you want
to disconnect.

I think there is an ansible script to do what you need, or some other script.
Simone, do you know where the clean shutdown script for HCI env?

Yes, it is of course the SPM, because this is a single node HCI environment
Both are done when you put a host to maintenance, but in hosted
engine
environment this
is not possible from engine since engine runs on the storage you want
to disconnect.
In fact. From here my question and doubts

Let's say that in a "standard production" HCI environment, with
suppose 3
nodes, you have a planned maintenance and you have to shutdown all three
nodes: the same applies when you have to shutdown the last node, but I
imagine you have also to do something with gluster when you shutdown the
second node because you have not quorum anymore, correct?

In fact. From here my question and doubts
Note that stopping the SPM and disconnecting from storage is not the same as
stopping vdsm service.
You need to use vdsm API to do this. This can be done with vdsm-tool command
or with vdsm client library.

applies when you have to shutdown the last node, but I imagine you have also to do
something with gluster when you shutdown the second node because you have not quorum

The flow should be:
1. put host 1 to maintenance
2. put host 2 to maintenance
At this point you have only host 3 connected to storage.
3. Stop the SPM
4. Disconnect from storage
At this point there is no gluster mount on any host, so there is no
quorum isssue.
You should be able to shutdown the hosts at this point. I guess that gluster
services handle shutdown gracefully like any service should.

Looking at the bug comments, I'm not sure this ansible script address
the issues you reported. Please
file a bug if you still see these issues when using the script.
We may need to solve this in vdsm-tool, adding an easy way to stop the
spm and disconnect from
storage cleanly. When we have such way the ansible script can use it.

I would like to come back to this item.
I tried both on a physical environment and on a nested environment, both of
them composed of single host HCI 4.3.9 with Gluster
The playbook has to be executed on the engine
The high level steps for the role, and some of them don't apply to my env,
composed of single host, are:
- clean shutdown of all VMs except engine (eventual errors ignored)
- forced shutdown of all VMs with status != down, except engine
- shutdown (fence) of non hosted engine hosts configured with power mgmt,
one by one
- shutdown (in parallel, asynchronously, fire and forget) remaining non
hosted engine hosts via "ssh shutdown -h now" (when no qemu-kvm process
present any more on them) (eventual errors ignored)
- set global maintenance
Note: This task is run multiple times, because it is run on every hosted
engine host, while it shouldn't be necessary.... but it doesn't hurt...
(eventual errors ignored... but result is registered to be checked after)
- fail the job and stop if none of the set global maintenance commands
executed on hosted engine hosts succeeded
- shutdown (in parallel, asynchronously, fire and forget) the hosted engine
hosts via ssh
For the hosts without the engine VM running, the command is, without
waiting any more:
sanlock client shutdown -f 1 ; shutdown -h now
For the host with the engine VM running on top of it, the command is the
same, but it is waited that engine vm status is not up (using
"hosted-engine --vm-status" command)
- shutdown -h now on the engine (with async mode, fire and forget)
Snippet for hosted engine hosts shutdown:
- name: Shutdown of HE hosts
command: >-
ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no
-i /etc/pki/ovirt-engine/keys/engine_id_rsa -p {{ item.ssh.port
}}
-t root@{{ item.address }} '{{ he_shutdown_cmd }}'
async: 1000
poll: 0
with_items:
- "{{ he_hosts }}"
where the he_shutdown_cmd var is defined as:
he_shutdown_cmd: >-
while hosted-engine --vm-status | grep "\"vm\":
\"up\""
/dev/null;
do sleep 5;
done;
sanlock client shutdown -f 1;
shutdown -h now
Snippet for the Engine VM shutdown
- name: Shutdown engine host/VM
command: shutdown -h now
async: 1000
poll: 0
In my case running the playbook I get this in final lines of output:
TASK [ovirt.shutdown_env : Shutdown engine host/VM]
***************************************************************************
changed: [localhost]
TASK [ovirt.shutdown_env : Power-on IPMI configured hosts]
********************************************************************
TASK [ovirt.shutdown_env : Unset global maintenance mode]
*********************************************************************
Connection to novengine.example.net closed by remote host.
Connection to novengine.example.net closed.
In general the engine VM complete shutdown and then the host is able to
complete its own shutdown when the engine has powered off.
Anyway I see these gluster umount errors on console of host:
https://drive.google.com/file/d/1uMGkPa6eyJy7RVNC2K5G66zCpyzeeuBo/view?us...
I have tried several times on physical and nested environments and at least
one time it failed on both: the engine VM was always able to complete its
shutdown, while the host remained powered on, as if it didn't get the
shutdown command, or the "sanlock client shutdown -f 1 " command didn't
complete...
Here below an example where the engine stops at 13:00 and I see this in
host's /var/log/messages, with gluster notification errors every 5 minutes
(13:05, 13:10, ...):

Could it be useful to insert the
/usr/share/glusterfs/scripts/stop-all-gluster-processes.sh command, as
suggested by Strahil, after the sanlock one, in case of GlusterFS domain?
Also one further note:
inside the role it is used the ovirt_host_facts module. I get this when I
use it and debug its content:
{
"msg": "The 'ovirt_host_facts' module has been
renamed to
'ovirt_host_info', and the renamed one no longer returns ansible_facts",
"version": "2.13"
}
So perhaps it should be considered to change and use ovirt_host_info
instead? Any plan?
Thanks for reading.

Could it be useful to insert the
/usr/share/glusterfs/scripts/stop-all-gluster-processes.sh command, as
suggested by Strahil, after the sanlock one, in case of GlusterFS domain?
Also one further note:
inside the role it is used the ovirt_host_facts module. I get this when I
use it and debug its content:
{
"msg": "The 'ovirt_host_facts' module has been
renamed to
'ovirt_host_info', and the renamed one no longer returns ansible_facts",
"version": "2.13"
}
So perhaps it should be considered to change and use ovirt_host_info
instead? Any plan?
Thanks for reading.

Hello,
I would like to keep on with this to have a better experience.
Environment is physical 4.3.10 single host HCI that shows the same problems
as above.
So I modified the role file adding after sanlock shutdown the gluster stop
script
[root@ovengine tasks]# pwd
/root/roles/ovirt.shutdown_env/tasks
[root@ovengine tasks]# diff main.yml main.yml.orig
79d78
< /usr/share/glusterfs/scripts/stop-all-gluster-processes.sh
[root@ovengine tasks]#
Now the poweroff completes, even if get these errors about stopping swap
and gluster bricks filesystems:

When I power on again the server in a second time, the environment starts
ok in global maintenance and when I exit it, engine and gluster volumes
start ok.
Even if there is a 2-3 minutes delay (I already opened a thread about this)
from the moment when you see the storage domains up in the web admin gui
and the moment when they are truely up (file systems
/rhev/data-center/mnt/glusterSD/... mounted). So if in the mean time you
try to start a VM you get an error because disks not found...
