[ovirt-users] Move Self Hosted Engine to Standalone

2020-02-17 Thread 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] Template for Ubuntu 18.04 Server Issues

2020-01-28 Thread jeremy_tourville
I have built a system as a template on oVirt.  Specifically, Ubuntu 18.04 
server.  
I am noticing an issue when creating new vms from that template.  I used the 
check box for "seal template" when creating the template.

When I create a new Ubuntu VM I am getting duplicate IP addresses for all the 
machines created from the template.

It seems like the checkbox doesn't fully function as intended.  I would need to 
do further manual steps to clear up this issue.

Has anyone else noticed this behavior?  Is this expected or have I missed 
something?  

Thanks for your input!

[ovirt-users] Re: Strategy to Mange Ovirt VMs Created from Templates

2019-12-23 Thread jeremy_tourville
Thank you for your reply Luca, 
In general your work flow is helpful and makes sense to me.  

I meant to say above- "As part of the template creation process ***the Ovirt 
docs*** say to seal the VM".  

So I think I understand that you need to use both processes (seal template + 
cloudinit) to get everything to work as desired.  I'd still appreciate any more 
specifics about what sealing a VM does.

[ovirt-users] Strategy to Mange Ovirt VMs Created from Templates

2019-12-23 Thread jeremy_tourville
I want to be able to manage VMs using Ansible.  As part of the template 
creation process it says to seal the VM.  Can someone tell me what sealing does 
to a Linux VM?  I understand it removes some of things that make the VM unique 
but no real specifics.  

So, if I want to manage a VM created from a template would this general process 
work?-

Seal the VM
Install CloudInit and keys, accounts, etc
Shut off VM and create template from it.

Create new VM using Ansbile & CloudInit 
CloudInit would have just enough info so that you could manage the VM with 
Ansible.

Would that work?

I am just starting to explore what CloudInit can do and what it is.  I am brand 
new to it.  I didn't find enough info on template sealing to help me devise a 
full cycle management strategy.  Perhaps there are other/easier methods?  
Thanks for your advice and input.

[ovirt-users] Re: multiple vm got stack after gluster server hardware failure

2019-10-22 Thread jeremy_tourville
If you can define "stuck" with some more detail I am sure many here could help 
you further.  Are the VMs in question displayed as "paused" by the engine?  
Have you tried using virsh at the command line to see if you can shutdown or 
start the VMs?  I have found that sometimes virsh will work to interact with 
the VMs when the GUI interface will not.

[ovirt-users] Re: Ovirt Node 4.3.6 Logical Network Issue - Network Down

2019-10-22 Thread jeremy_tourville
I did some further testing.  In short, if I attach logical network/VLAN 103 to 
enp96s0f0 the network will come up and be available for use.  If I attach VLAN 
103 to enp96s0f1 the logical network never comes up.

I have sort of answered my own question, though I don't fully understand why.  

If my memory serves me correctly, I had used the exact same router setup on my 
4.2.7 Ovirt node.  I believe I was able to use VLAN 103 on either interface 
without issue.  Is there something different about 4.3.6 Ovirt node?  Is there 
some sort of rule that won't allow a logical network to be shared with the same 
interface as the interface for storage/gluster?

2019-10-21 Thread jeremy_tourville
I am unable to tell from your question what research you have done or what you 
have tried so far.  Anyway, review this- 
https://ovirt.org/documentation/admin-guide/chap-Logical_Networks.html.  
Generally speaking, the checkbox for "Connect to physical network" should not 
be needed for your example.  You most likely will need to set up VLANs when you 
create the logical network.

No just a single host.  I didn't see any documentation that said you need two

I did some further testing by installing ipmitool on my laptop.

Maybe a one of the DEVs could chime in and confirm if this is expected behavior?

VLAN 101 is attached to enp96s0f0 which is my ovirtmgmt interface.  -IP range 
172.30.50.x
VLAN 102 is attached to enp96s0f1 which is my storage NIC for gluster.  -IP 
range 172.30.51.x
VLAN 103 is attached to enp96s0f1 is intended for most of my VMs that are not 
infrastructure related.  -IP range 192.168.2.x

I am pretty confident my router/switch is setup correctly..  As a test, I can 
go to localhost>networking>add VLAN and assign enp96s0f1 to VLAN 103 and it 
does get an IP address in the 192.168.2.x range.  The host can also ping the 
192.168.2.1 gateway.

Why doesn't the engine think the VLAN is up?  Which logs do I need to review?

[ovirt-users] Thin pool best proctices

2019-10-07 Thread jeremy_tourville
After a week of downtime from a thin pool that had 100% full metadata I decided 
to rebuild my single node.  My post was formerly titled: Ovirt 4.2.7 won't 
start and drops to emergency console.  I have backups of nearly all my VMs and 
I am working on importing them.  I went from version 4.2.7.1 to 4.3.6.  I am 
comfortable with LVM but I am new to administering thin pool LVM.  I am asking 
myself what can I do to avoid this headache in the future?  What practical 
steps should I take?
-Regular backups
-Monitoring
-Proper configuration

It's the last one that is the most difficult for me.  You don't know what you 
don't know Can anyone share tips and advice?

I learned that /etc/LVM has backups.  It should be part of the backup strategy. 
 I now know that thin pools have a special metadata volume that should be 
monitored for disk space.

At the time I built the system I used the gedploy gluster config file.  I had 
assumed the values in there were "safe".  As I found out the hard way, reality 
proved otherwise.  I was reading elsewhere about allowing the thin volume to 
grow 20% as needed but no real mention of how to do that or a good example.  As 
I understand it, the config to make that happen exists in lvm.conf.  Is that 
right?

Have there been any changes in Ansible GlusterFS setup  since 4.2.7 to choose 
different "safe" values with newer versions?  

I hope my comments won't be taken as critical by any Dev Team members regarding 
Ansible.  My sole intent for this post is so I learn what to do better/right 
next time.  I do have most of my VMs and the few I lost are not critical.  It 
was lucky that I learned a hard lesson the easy way.

Thanks for your input!

2019-10-02 Thread jeremy_tourville
Sorry for the multiple posts.  I had so many thoughts rolling around in my 
head.  I'll try to consolidate my questions here and rephrase the last three 
responses.

>>>"Try to get all data in advance (before deactivating the VG)". 

Can you clarify?  What do you mean by this?

>>>"I still can't imagine why the VG will disappear. Try with 'pvscan --cache' 
>>>to redetect the PV. Afrer all , all VG info is in the PVs' headers and 
>>>should be visible no matter the VG is deactivated or not."

I'll try that and see what happens.

>>>"Is this an oVirt Node or a regular CentOS/RHEL"

oVirt Node


>>>"You got 15GiB of metadata, so create your new metadata LV at least 30 GiB."

My presumption is that 15 GB is the max size the was specified when it was 
initially built but not the actual size right now, but yes, making it larger 
does make sense.  I was curious to know what the present size is.  Also, 
lvconvert man page specifies  a supported value between 2M and 16G  I will 
create a larger metadata volume assuming I can get the procedure to work 
properly  I am having some difficulty with the procedure, see below.


My most important question was here:
I am trying to follow the procedure from 
https://access.redhat.com/solutions/3251681 I am on step #2.  Step 2a and 2b 
work without issue.  Step 2c gives me an error.  

Here are the values I am using: 

# lvcreate -L 2G gluster_vg3 --name tmpLV 
(created with no issues)

# lvchange -ay gluster_vg3/tmpLV 
(command completed with no issues)

# lvconvert --thinpool gluster_vg1/lvthinpool --poolmetadata gluster_vg3/tmpLV 
Error:
VG name mismatch from position arg (gluster_vg1) and option arg (gluster_vg3) 

Do I need to create the LV on the same disk that failed?  (gluster_vg1) 
i.e.- perhaps my command is wrong and should be lvconvert --thinpool 
gluster_vg3/lvthinpool --poolmetadata gluster_vg3/tmpLV
** Perhaps this command assumes you already have a VG=gluster_vg3 and 
LV=lvthinpool?

2019-10-01 Thread jeremy_tourville
http://man7.org/linux/man-pages/man7/lvmthin.7.html
 Command to repair a thin pool:
   lvconvert --repair VG/ThinPoolLV

   Repair performs the following steps:

   1. Creates a new, repaired copy of the metadata.
   lvconvert runs the thin_repair command to read damaged metadata from
   the existing pool metadata LV, and writes a new repaired copy to the
   VG's pmspare LV.

   2. Replaces the thin pool metadata LV.
   If step 1 is successful, the thin pool metadata LV is replaced with
   the pmspare LV containing the corrected metadata.  The previous thin
   pool metadata LV, containing the damaged metadata, becomes visible
   with the new name ThinPoolLV_tmetaN (where N is 0,1,...).

   If the repair works, the thin pool LV and its thin LVs can be
   activated, and the LV containing the damaged thin pool metadata can
   be removed.  It may be useful to move the new metadata LV (previously
   pmspare) to a better PV.

   If the repair does not work, the thin pool LV and its thin LVs are
   lost.

This info seems to conflict with Red Hat advice.  Red Hat says if metadat 
volume is full don't run a lvconvert --repair operation.  Now I am confused.  I 
am familiar with LVM and comfortable with it but this is my first time trying 
to repair thin LVM.  The concepts of a metadata volume are new to me.

I don't know why I didn't think to get some more info regarding my storage 
environment and post it here earlier.  My gluster_vg1 volume is on /dev/sda1.  
I can access the engine storage directory but I think that is because it is not 
thin provisioned.  I guess I was too bogged down in solving the problem when 
I'm stuck in emergency mode.  I had to  sneaker net my USB drive to my system 
so I could capture some info.  Anyhow here it is:

"lvs -a" does not list the logical volume I am missing.
"lvdisplay -m /dev/gluster_vg1-lvthinpool-tpool_tmeta" does not work either.  
Error message is: Volume Group xxx not found.  Cannot process volume group xxx."

I am trying to follow the procedure from 
https://access.redhat.com/solutions/3251681
I am on step #2  Step 2a and 2b work without issue.  Step 2c give me an error.  
Here are the values I am using:
# lvcreate -L 2G gluster_vg3 --name tmpLV 
# lvchange -ay gluster_vg3/tmpLV
# lvconvert --thinpool gluster_vg1/lvthinpool --poolmetadata gluster_vg3/tmpLV

VG name mismatch from position arg (gluster_vg1) and option arg (gluster_vg3)

Do I need to create the LV on the same disk that failed?  (gluster_vg1)
Is creating a new LV on (gluster_vg3) ok for this situation?

vgs displays everything EXCEPT gluster_vg1
"dmsetup ls" does not list the VG in question.  That is why I couldn't run the 
lvchange command.  They were not active or even detected by the system.

OK, I found my problem, and a solution: 
https://access.redhat.com/solutions/3251681
# cd /var/log
# grep -ri gluster_vg1-lvthinpool-tpool
My metadata is 100% full !!! 

Now, how do I find out how big my original metadata size was so I can make the 
new one the correct size?

2019-09-29 Thread jeremy_tourville
Yes, I can take the downtime.  Actually, I don't have any choice at the moment 
because it is a single node setup. :)  I think this is a distributed volume 
from the research I have performed.  I posted the lvchange command in my last 
post, this was the result-  I ran the command lvchange -an 
/dev/gluster_vg1/lv_datadisks When I do this I get the message "Volume group 
"gluster_vg1" not found. Cannot process volume group gluster_vg1".  I also 
tried the command the way you specified with just the LV and get the same 
results. 

I had placed the system in Global maintenance mode prior to the reboot.  Upon 
reboot I got the messages about the various gluster volumes not being able to 
be mounted because of timeout issues.  That is what started my OP.  I think we 
are both thinking along the same lines regarding the issue.  I think the 
question is how do you  fix a volume that the system won't mount?  It does seem 
likely that the thinpool needs to be repaired but what do you do if you can't 
even perform the first step in the procedure?

[ovirt-users] Re: Ovirt 4.2.7 won't start and drops to emergency console

2019-09-29 Thread jeremy_tourville
Thank you for the reply.  Please pardon my ignorance, I'm not very good with 
GlusterFS.  I don't think this is a replicated volume (though I could be wrong) 
 I built a single node hyperconverged hypervisor.  I was reviewing my gdeploy 
file from when I originally built the system.  I have the following values:
PV = /dev/sda
VG1= gluster_vg1
LV1= engine_lv (thick)
LV2 = gluster_vg1 thinpool
LV3 = lv_vmdisks (thinpooll)
LV4 = lv_datadisks (thinpool)

So according to the article I read in my OP, it says to deactivate the volumes 
under the thin pool as the first step.  I ran the command lvchange -an 
/dev/gluster_vg1/lv_datadisks  When I do this I am told Volume group 
"gluster_vg1" not found.  Cannot process volume group gluster_vg1.

That seems consistent with the timeout error message.  How do you fix this if 
you can't access the volumes?  Thoughts?

[ovirt-users] Ovirt 4.2.7 won't start and drops to emergency console

2019-09-28 Thread jeremy_tourville
I see evidence that appears to be a problem with gluster.  /var/log/messages 
has multiple occurrences of: WARNING: /dev/gluster_vg1/lv_:  Thin's 
tihin-pool needs inspection.  Also, if I run  vgs I am returned info for my 
other volume groups but not gluster_vg1.  Lastly, when reviewing journalctl -xb 
| grep -i timed  I see messages from systemd
Job dev-gluster_vg1-lv_vmdisks.device/start timed.out.
Timed out waiting for device dev-glustet_vg1-lv_vmdisks.device

Thses messages are happening for both
/dev/gluster_vg1/lv_datadisks
/dev/gluster_vg1/lv_vmdisks

 I did review the article here but I am unable to change to VG1.

Can anyone assist with a procedure on how to repair?

[ovirt-users] Upgrade Hyperconverged Single Node

2019-06-18 Thread jeremy_tourville
Does this page apply?
https://www.ovirt.org/documentation/upgrade-guide/chap-Updates_between_Minor_Releases.html

My Node is presently running 4.2.7 and I'd like to upgrade to 4.3.4

I was reading about needing to fail over so the SPM role is available (ie more 
than 1 host) 

If the page above is not applicable what is the procedure?

Thanks!
