Hi,

I think that there's already a bug on this issue:

I can confirm that multiple hosts:port in a mount spec is not supported by
the current code.

You can see all the supported formats here:

A single DNS entry did not work. Red Hat's oVirt did not like mounting
it even though it works fine via command line. :-/

I now have a Red Hat ticket open so we will see what happens on that front.

Hi,

The same as the notification regex. Using hosted-engine
--set-shared-config   --type=

Executing hosted-engine --get-shared-config xxx (or anything else that
does not exist) should give you the list of all types and keys you can
change (on 4.2 fo sure and 4.1 very probably too).

Yes, indeed!

How can I change this internal Python setting?

[ovirt-users] Re: Turn Off Email Alerts

[Martin Sivak]

Hi,

two clarifications:

Hosted engine is sending those emails using built-in Python SMTP
client that talks directly yo the SMTP server specified during install
time. We default to localhost, but you might have changed it.

> notify.state_transition : maintenance|start|stop|migrate|up|down, type : 
> broker

The value here is a regular expression that is matched against the
state transition string in the email.

[ovirt-users] Re: Turn Off Email Alerts

[Douglas Duckworth]

Thanks for sharing

I may want to do that

Though first I want to understand how the emails are arriving.

I stooped ovirt-engine-notifier.service and postfix.service on all hosts
and the hosted engine.  So how are the email being delivered?  They are not
running senmail so I don't understand what daemon's sending these messages.

Hi,
you can change the list of status you want to be notified about
with hosted-engine --set-shared-config notify.state_transition
The default is:

[root@hehost01 ~]# hosted-engine --get-shared-config
notify.state_transition --type=broker

notify.state_transition : maintenance|start|stop|migrate|up|down, type :
broker

 Hi

 How do I turn off hosted engine alerts?  We are in a testing phase so
 these are not needed.  I have disabled postfix on all hosts as well as
 stopped the ovirt notification daemon on the hosted engine.  I kept it
 running while putting /dev/null in
 /usr/share/ovirt-engine/services/ovirt-engine-notifier/ovirt-engine-notifier.conf
  for
 mail server.  Yet I still get alerts for every thing done such as putting
 hosts in maintenance mode.  Very confusing.

[ovirt-users] Bricks do not appear in oVirt Manager UI under Hosts unless manually created on nodes.

[payden . pringle+ovirtlist]

I have a CentOS 7.5 system running the oVirt-Engine package as the manager for 
three oVirt Nodes (version 4.2). Two of the nodes have a 200GB disk and one has 
a 2GB disk. I am attempting to create a Gluster Volume that replicates between 
the two 200GB disks with the 2GB as Arbiter. 

When I create the bricks by going to Hosts > host1 > Storage Devices > Create 
Brick (with the 200GB device selected), it succeeds, but no bricks appear under 
the Bricks tab for the Host. Doing the same for host2 and host3 results in the 
same problem. 

If I run the following command on a host `gluster volume create test-volume 
replica 3 arbiter 1 192.168.5.{50,60,40}:/gluster-bricks/200GBbrick/test`, it 
creates the volume correctly and the bricks then appear as they should. 
However, then these Bricks are labeled as "Down" and when I go to Storage > 
Volumes, I get this error:
```
Uncaught exception occurred. Please try reloading the page. Details: 
(TypeError) : Cannot read property 'a' of null
Please have your administrator check the UI logs
```
The Volume is also shown as "Down". SELinux is enabled on my CentOS 7.5 system. 

I'm not really sure what the correct method is to create bricks then a Volume 
in Gluster through the oVirt Management UI, but I've followed the guides and 
this is where it has got me.

I agree however we are in testing phase so I make changes a lot.  Therefore
alerts are not presently needed.

So how to I turn them off?

These steps do not work on hosted engine:


me@ovirt-engine[~]$ sudo systemctl stop postfix.service
me@ovirt-engine[~]$ sudo systemctl stop ovirt-engine-notifier.service
me@ovirt-engine[~]$ sudo systemctl status ovirt-engine-notifier.service

I still get an email every time I put a host in maint mode for example.

Not for me. After restarting the engine,it doesn't matter if I restart the Hypervisors, I only get the "protocol=gluster" when I restart the VMs... migration is 
not enough.


"virsh -r dumpxml "

That is possibly why the leak simply appeared

Hello,
I have a hyperconverged, self hosted ovirt cluster with three hosts,
running 4 VM's. The hosts are running the latest ovirt node. The
VM's are Linux, Windows server 2016, and Windows Server 2008r2. The
problem is with any host running the 2008r2 VM will run out of memory
after 8-10 hours, causing any VM on the host to be paused, and making
to host all but unresponsive. This problem seems to only exist with
this specific VM. None of the other running VM's have this problem.
I can resolve the problem by migrating the VM to a different host,
then putting the host into maintenance mode, the activating it back.
The leak appears to be in glusterfsd. Is there anything I can do to
permanently fix this?

Thanks, I thought about that but I have not tried it. I will add it to
my list to check today and will report back if it works (though I don't
see why it wouldn't). It is good to know that someone else has at least
had success with having a DNS entry for the multiple CephFS monitor hosts.

[Darrell Budic]

3.12.13 is now showing up  in the storage repo.

I can confirm it fixes the leak I’ve been seeing since 3.12.9 (upgraded one of 
my nodes and ran it overnight). Hurray!

[ovirt-users] Re: Weird Memory Leak Issue

[Darrell Budic]

There’s a memory leak in gluster 3.12.9 - 3.12.12 on fuse mounted volumes, 
sounds like what you’re seeing.

The fix is in 3.12.13, which should be showing up today or tomorrow in the 
centos repos (currently available from the testing repo). I’ve been running it 
overnight on one host to test, looks like they got it.

[ovirt-users] Weird Memory Leak Issue

[Cole Johnson]

Hello,
I have a hyperconverged, self hosted ovirt cluster with three hosts,
running 4 VM's.  The hosts are running the latest ovirt node.  The
VM's are Linux, Windows server 2016, and Windows Server 2008r2.  The
problem is with any host running the 2008r2 VM will run out of memory
after 8-10 hours, causing any VM on the host to be paused, and making
to host all but unresponsive. This problem seems to only exist with
this specific VM.  None of the other running VM's have this problem.
I can resolve the problem by migrating the VM to a different host,
then putting the host into maintenance mode, the activating it back.
The leak appears to be in glusterfsd.  Is there anything I can do to
permanently fix this?

Looks like a bug,aybe vdsm is not parsing the mount spec correctly.

Please file vdsm bug and attach vdsm logs showing the entire flow.

Regardless, I'm not sure how well oVirt with cephfs is tested, or
recommended.

Adding Yaniv t9 add more info on this.

[ovirt-users] Multiple CephFS Monitors cause issues with oVirt

[Stack Korora]

Greetings,

My setup is a complete Red Hat install.
Manager OS: RHEL 7.5
Hypervisors OS: RHEL 7.5
Running Red Hat CephFS (with their Ceph repos on all of the systems)
with Red Hat Virtualization (aka oVirt).
Everything is fully patched and updated as of yesterday morning.

Yes, I have valid Red Hat support but I figured this was an odd enough
problem that the community (and the Red-Hat-ers who hang out on this
list) might have a better idea of where to start. (Although I might open
a ticket anyway just because that is what support is for, right? :)

Quick background:

Your /etc/fstab when you mount a nfs should probably look something like
this:
:/path/ /mount/point nfs  0 0

Just one IP is needed. Since part of the redundancy for Ceph is in the
monitors, to mount CephFS the fstab should look something like this:

,,:/path/
/mount/point ceph  0 0

Both the Ceph community and Red Hat recommend the comma separator for
mounting multiple CephFS monitor nodes. (See section 4.2 point 3)
https://access.redhat.com/documentation/en-us/red_hat_ceph_storage/2/html/ceph_file_system_guide_technology_preview/mounting_and_unmounting_ceph_file_systems


Now to oVirt/RHV.

When I mount my Data Domain path as a Posix file system with a path of
":/path/" it works splendidly well (especially after
the last Red Hat kernel update!). I've done a bunch of stuff to it and
it seems to work every time. However, I don't have the redundancy of
multiple Ceph Monitors.

When I mount my Data Domain path as a Posix file system with a path of
",,:/path/"
most things seem to work. But I noticed a higher rate of failures. The
only failure that I can trigger 100% of the time though is to mount a
second data import domain and attempt to copy a vm disk from the import
into the CephFS Data domain. Then I get an error like this:

would
VDSM ovirt01 command HSMGetAllTasksStatusesVDS failed:
low level Image copy failed:
(u'Destination volume 7c1bb510-9f35-4456-8d51-0955f788ac3e error:
ParamsList: sep , in
/rhev/data-center/mnt/,,:_ovirt_data/70fb34ad-e66d-43e6-8412-5e020baa34df/images/23991a68-0c43-433f-b1f9-48b1533da54a',)

Uh, oh. It seems that the commas in the mount path are causing the
problems. So I went looking through the logs for "sep , in" and found a
bunch more hits which makes me think that this is actually the problem
message.

I've switched back to just one IP address for the time being but I
obviously want the Ceph redundancy back. While running on just one IP,
the vm disk that refused to copy before had no problem copying. The
_only_ change I made was dropping two of the three IP's from the Data
Domain path option.

Is this a bug, or did I do something wrong?

Does anyone have a suggestion for me to try?

Thank you!

it might happen you are solving the same issue as is discussed within this

[ovirt-users] Re: snapshots upload

[Shani Leviim]

Hi David,

It seems that you're trying to create a RAW SPARSE disk.

According to [1], the RAW Sparse disks' configuration is supported for NFS
storage domains (not for block domains like iSCSI or FCP).
Can you please verify the target storage domain's type on your script?
