[ovirt-users] Re: Move Self Hosted Engine to Standalone

[Jeremy Tourville]

I did get a little further.

First I ran engine-cleanup on my new engine where I will be running the restore 
operation. (I had previously run the engine-setup script on this machine)

Then I ran this-

[root@engine ~]# engine-backup --mode=restore 
--file=ovirt-engine-backup-20200217125040.backup 
--log=ovirt-engine-backup-20200217125040.log --provision-db --provision-dwh-db 
--restore-permissions
Start of engine-backup with mode 'restore'
scope: all
archive file: ovirt-engine-backup-20200217125040.backup
log file: ovirt-engine-backup-20200217125040.log
Preparing to restore:
- Unpacking file 'ovirt-engine-backup-20200217125040.backup'
Restoring:
- Files
Provisioning PostgreSQL users/databases:
- user 'engine', database 'engine'
FATAL: Existing database 'engine' or user 'engine' found and temporary ones 
created - Please clean up everything and try again

Time to research further for that FATAL error message.  Isn't that the purpose 
of engine-cleanup though?  Why the conflict?

OK, I was able to get the backup completed.  I am a little confused on how to 
do the restore though.  
https://www.ovirt.org/documentation/self-hosted/chap-Backing_up_and_Restoring_an_EL-Based_Self-Hosted_Environment.html

Is this link even applicable?  My environment is a single node, not EL based.  
Anyhow, here is what I have so far-

[root@engine glusterfs]# engine-backup

Done.
[root@engine glusterfs]#

I moved the backup file to my new engine.
How do I perform the restore?

The directions say:

# engine-backup --mode=restore --file=file_name --log=log_file_name 
--provision-db --provision-dwh-db --restore-permissions

What is the file name and log_file name?  Do I need to do something to unpack 
my backup file?

Anything in libvirt/vdsm logs ?

Did you update gluster recently ? I had such issues when gluster refused 
reading of shards.
 Can you read the disk via:
sudo -u vdsm dd if=/rhev/full/path/to/mountpoint/long_string_representing_file 
of=/dev/null bs=4M status=progress

What happens when you run dd as root -> can you read from the image ?


Any errors in gluster logs ?

[ovirt-users] paused vm's will not resume

[eevans]

I have 2 vm's, which are the most important in my world, that paused and will 
not resume. I have googled this to death but no solution. It stated a lack of 
space but none of the drives on my hosts are using more than 30% or there space 
and these 2 have ran on kvm host for several years and always had at least 50% 
free space. 
I like ovirt and want to use it but I cannot tolerate the down time. If I 
cannot get this resolved, I'm going back to kvm hosts. I am pulling my hair out 
here.
If anyone can help with this issue, please let me know.

Hi Adrian,

I don't understand yoiur layout.
Can you clarify the following:
/dev/sdd was a PV 
/dev/sdd was not the only PV in the VG
A thin LV was created from the VG
The Thin LV was used as a gluster brick.

I don't get why you want the new disk to become /dev/sdd again, as it won't 
have the necesary LVM metadata.

Gluster works with miunt points . You can mount whatever you wish at 
/gluster_bricks/data2 and it will try to use that. As the brick doesn't exist 
any more - you will have to use 'reset-brick' or 'replace-brick' commands.

Strahil Nikolov

[ovirt-users] foreman integration

[eevans]

I have ovirt 4.3 and foreman 1.9.3. both with self signed certificates. Foreman 
is a vm on the ovirt cluster. I added foreman as an external provider in ovirt, 
but when I try to add ovirt as a compute resource in foreman I get an ssl 
error.  I found several fixes that prevented the error but the data center and 
quota fields would not populate.

The exact error is:

Unable to save
SSL_connect returned=1 errno=0 state=error: certificate verify failed

Has anyone else had this problem? 

Any help would be greatly appreciated.

[ovirt-users] Re: Damaged hard disk in volume replica gluster

[adrianquintero]

HI Strahil,
I am also running into an issue trying to replace a brick.

1.-/dev/sdd failed which is our /gluster_bricks/data2/data2 brick, hat disk was 
taken out of the array controller and added a new one.

2.-there are quite a bit of entries related to /dev/sdd , i.e.

[root@host1]# dmsetup info  |grep sdd
Name:  gluster_vg_sdd-gluster_thinpool_gluster_vg_sdd-tpool
Name:  gluster_vg_sdd-gluster_thinpool_gluster_vg_sdd_tdata
Name:  gluster_vg_sdd-gluster_thinpool_gluster_vg_sdd_tmeta
Name:  gluster_vg_sdd-gluster_thinpool_gluster_vg_sdd
Name:  gluster_vg_sdd-gluster_lv_data2

this causes the OS to see the new disk as /dev/sde (the controller presents it 
as /dev/sde)

array C

  Logical Drive: 3
 Size: 2.7 TB
  ...
 Disk Name: /dev/sde 
 Mount Points: None
 .
 Drive Type: Data
 LD Acceleration Method: Controller Cache

If i just remove all the thinpool entries (if i find them) do you think that 
might do the trick?

thanks,

Adrian

That's great news.  I now have the agents running on the engine and hosts 
without problem.

What standard Zabbix monitoring templates do you recommend for the HE?  What 
about the hosts?

Also, are there any custom and/or oVirt-specific monitoring templates you 
recommend I use?

Your feedback is much appreciated.

Hello,

I have not used this script myself so I don't have a resolution for you,
however I recently wrote an article regarding a simple method to backup
oVirt VMs using ansible without the need of any complicated software or
proxy VMs involved. Here is the link to the article if it's helpful to you:

Looks like copying image failed with ENOENT while reading
offset 12348028416 (11.49 GiB).

I never seen such failure, typically after opening a file read will never
fail with such error, but in gluster this may be possible.

Please share vdsm log showingn this error, it may add useful info.

Also glusterfs client logs from
/var/log/glusterfs*/*storage.cyber-range.lan*.log

Kevin, Krutika, do you have an idea about this error?

Nir

Can you take a backup  of the original, build the new one, then do a restore?

[ovirt-users] Move Self Hosted Engine to Standalone

[jeremy_tourville]

I have a single oVirt host running a self-hosted engine.  I'd like to move the 
engine off the host and run it on a standalone server. I am running Software 
Version:4.3.6.6-1.el7  Can anyone tell me what the procedure is for that?

[ovirt-users] Re: hosted-engine --deploy --restore-from-file fails with error "Domain format is different from master storage domain format"

[djagoo]

Hi Shani,

I just tried it.

I created a new DC and cluster, added a temporary host to this cluster which 
served as SPM. The new DC showed up as V5.
Then I activated maintenance on one of the V4 SDs and detached it from my 
production domain. After I attached it to the V5 dummy domain it was updated to 
V5 format as you predicted. I detached it again but could not reattach it to 
the production domain "There are no compatible Storage Domains to attach to 
this Data Center". So this seems not to be the solution :(

Do you have another idea or am I doing something wrong?

Regards,

Marcel

[ovirt-users] Re: where can I find the repositories specific to 4.3.7

[adrianquintero]
