It looks like it's only in oVirt-engine that there's an issue. The host
seems happy enough.

You cannot assign this role to the host interface directly, but to the

[ovirt-users] Re: Memory usage inclines

[Darrell Budic]

Grab a shell on your hosts and check top memory use quick. Could be VDSMD, in 
which case restarting the process will give you a temp fix. If you’re running 
hyperconvered, check your gluster version, there was a leak in versions 3.12.7 
- 3.1.12 or so, updating ovirt/gluster is the best fix for that.

[ovirt-users] Re: losing ib0 connection after activating host

[Douglas Duckworth]

Hi Dominik,

I have added LACP bond network to all hosts and renamed the Hosted Engine using 
"/usr/share/ovirt-engine/setup/bin/ovirt-engine-rename."

However, I am still missing the option to assign Migration and Management 
network roles to this new bond.

Can you advise where I can find this option?

Hi Alexis,
what do you mean with "LVM doesn't get all the data"? Do you use thin
provisioned or something like that?
Otherwise if you create an LV with N Gb in size, that is its size forever
if you don't manually change it.
In any case for block based and file based trim/discard functionalities and
limitations you should read this below if not already done:

HIH,
Gianluca

[ovirt-users] LVM vs DF discrepancy usage (with NFS)

[Alexis Grillon]

Dear All,

i follow here the suggestion of Tal and share this problem (for which
there's a workaround) with you, hoping someone can identify something
which can explain this problem.


. Settings :

We work mostly on HP (ProLiant DL380 Gen9, DL380e Gen8, DL180 G6), with
an ovirt cluster DL180 G6.

On the storage side, we use the host harddrive mount in NFS (i know it's
not the "by the books optimal settings").


. Installation :

Each host is installed with the node iso.
Harddrive are not SSD and are in RAID5 (physical or logical)
Each harddrive has a standard oVirt node install auto partitionning,
except for one thing, we reduce the / mount point to make a new
partition in XFS for the data storage mount point (the partition is
inside LVM in our case)

. The problem :

We experienced on all of this hosts huge discrepancy between the LVS
command and DF on usage of the different partition. (sometimes up to a
90% difference !)
Spoiler alert, DF is right, LVM is wrong.
I think (but i might be wrong), that when we delete -in ovirt- a lot of
data on the drive, LVM doesn't get all the data about that.


. Workarounds :

By speaking about with lvm dev, we found a workaround :
fstrim who force LVM to check if data has been deleted or not.

Another solution is to use a partition for data which is not a part of
LVM, that works well too :)


One last thing : we saw this on data partition of our hosts, but it's
not impossible it might the case on the ovirt partition too (the current
discrepancy might be normal)


If someone has an idea of what we did wrong, or if there's a good reason
for this to happened...

Thank you.

[ovirt-users] Memory usage inclines

[Tony Brian Albers]

Hi guys,

We have a small test installation here running around 30 vms on 2
hosts.

oVirt 4.2.5.3

The hosts each have 512 GB memory, and the vms are sized with 4-8 GB
each.

I have noticed that over the last months, the memory usage in the
dashboard has been increasing and is now showing 946.8 GB used of
1007.2 GB.

What can be causing this?

TIA,

[ovirt-users] Re: IP change of a storage domain

[Elad Ben Aharon]

Hi,

You can change the storage connection details (IP address, path/LUN, port,
etc.) without removing the storage domain.
IIRC, the domain has to be in maintenance for that.
For file based storage, you can do it via the Webadmin and for block based
storage, via REST API.

See
https://ovirt.org/develop/release-management/features/storage/manage-storage-connections/

[ovirt-users] IP change of a storage domain

[Demeter Tibor]

Dear All, 

I have to change an IP address of one of my storage domains. 
How is safe that? There are a lot of disk what running from what and parts of 
some running VMs. 

I thought the whole procedure like this: 

- stop vms 
- remove storage domain from inventory 
- delete storage domain from inventory (is it needed?) 
- change IP 
- re-add storage domain as new to inventory 
- import disks from storage domain 

Need to re-add disks to VMs as new after the import? Or it will automatically? 
Is it will a new storage domain in the engine or will same as? 

- start vms 

Please check my todo list, where I'm was wrong. 
Thanks in advance, 

Regards, 
Tibor

[ovirt-users] VDSM issues.

[Nicholas Vaughan]

Hi,

We have 4 hosts on Version 4.2.1.7-1.el7.centos, but we have got an issue
with vdsm on our SPM which is causing some issues and we cannot migrate any
VM's from that host.

If I run 'vdsm-client Host getAllTasksStatuses' on the host, it returns 4
tasks, message: running job 1 of 1, code:0,  taskState:running for
all 4 tasks.

However we have no operations in the engine that should be running (not a
hosted engine), just a stuck task that logs every minute or so 'Clearing
asynchronous task Unknown that started at Thu Dec 06 14:42:03 GMT 2018'.

If I try to manually stop the task, 'vdsm-client Task stop taskID=' we get
'code=411, message=Task is aborted: u'task guid' - code 411'.  So then If I
try and clean the task it can't because its in a running state: vdsm-client:
Command Task.clear with args {'taskID': 'task guid'} failed: (code=410,
message=Operation is not allowed in this task state: ("can't clean in state
running",))

Attached is part of the (sanitised) VDSM log that is recurring.  VDSM
version is: vdsm-client-4.20.17-1.el7.centos.noarch

Does anyone have any ideas other than shutting down all the VM's on that
host and restarting it?  Not sure if I can restart the VDSM service with
VM's running?

Thanks,
Nick

No, I didn't.
what are the next steps
i ve allready reinstalled the host. i 've selected deploy at hosted engine,
but it seems not to work.

[ovirt-users] Re: ovirt 4.2.7.1 fails to deploy hosted engine on GlusterFS

[Johannes Jurgens Loots]

I had this issue this week as well.

When asked about the glusterfs that you self provisioned you stated 
"ovirt1.localdomain:/gluster_bricks/engine”

So I am new to gluster but as a client of gluster you can only refer to it via 
volume name.
host:/

Hence maybe try ovirt1.localdomain:/engine.

That did the trick for me. Hope this helps. Cost me a week.
