[ovirt-users] Data Recovery from snapshot

[Jim Kusznir]

Hi:

With yet another gluster disk failure / gluster collapse, it appears I lost
the "main" backing image for one of my vm servers.  I have snapshots still
in tact (or at least, appear to be), but the main image is gone.

The main server process stores a backup at regular intervals in its disk,
and that would have been changed data, so it would be in the snapshot
rather than the base image.  Is there any way to recover this one .tar.gz
file from the snapshot with the missing main image?  This is a backup of
dynamic data, and without it, I will have lost several customers data, some
of which cannot be recreated/regenerated.

it also appears that my backup (gluster geo-replication) did not work (had
crashed a while ago, and has a very old backup of this image).

[ovirt-users] Re: Failed to deploy ovirt engine with "hosted-engine --deploy"

[Bong Shau Fui]

Hi Simone:
   Ok, noted on the config part.  Is there any bug report that points to KVM on 
ESXi problem?  I'm just curious.  Thanks.

[ovirt-users] Re: Hosted Engine deploy failed on new HCI build

[Jayme]

Bill,

I think this is the same problem.  I figured out the vnc stuff earlier and
got a console to the engine and got its status up but I don't know if
that's enough.  I feel like all steps haven't been completed.  Once you
figured out what was going on did you have to redeploy the engine again?

[ovirt-users] Re: Hosted Engine deploy failed on new HCI build

[William Dossett]

That happened to me twice… the second time I figure it out and it was 
networking.  

 

I am not familiar with the hosted-engine ---console…

 

The person that helped me said to do the following:

 

Run on your first host
   hosted-engine --add-console-password
to set a temporary VNC password and then connect to it over VNC with something 
like
   remote-viewer vnc://:

 

Which got me in and allowed me to fix the networking once I saw what was wrong… 
 can you get to the console like that?

 

Regards

Bill

I haven't had much luck with this yet I completely wiped the three hosts and 
did the entire install over again from the ground up only this time I used dhcp

in the exact step as before, waiting for the VM to come back but never does.

[ovirt-users] Re: adding hosts problems with GlusterFS

[william . dossett]

I found the problem...

with the cockpit deploy, all disks are blacklisted from multipath by a script 
called blacklist_all_disks.sh

This does not happen when a host is added manually.   To work around the 
problem edit /etc/multipath.conf  add the second line to the file below... this 
makes sure that vdsm will not ever mondify this file again.

 VDSM REVISION 1.5
# VDSM PRIVATE

then add the following to the end of the file


blacklist {
devnode "*"
}

this blacklists all disk from multipath.

Had to dig fairly deep for this, but now its working.

 Sorry for the confusion, Initially I thought it is an issue from our

 But this issue is from oVirt. So could you please help me.

 *Steps to reproduce :*
 1) Attach the disk to any VM
 2) Perform some read and write operation in the VM which will increase
 the disk level - 'Read data rate / Write data rate / disk.read.latency
 / disk.write.latency'
 3) Now when I bring down the VM, all the disk statistics should come
 down to be zero *But it is still retaining with last known value when
 the VM was in UP state.*


 *Expected : All values should go to ZeroActual : All values retains the
 last known values when the VM was in UP state. *

[ovirt-users] Re: adding hosts problems with GlusterFS

[william . dossett]

I did it from the UI.  I've just removed and re-added the host and I can't see 
any thing different I could do while adding it.  all the disks are locked.  

the brick is mounted in /gluster_bricks, but does not show in the bricks tab... 
 actually I think it may have been in the new volume view though.  I didn't 
actually want that volume though now that I realize I don't need an ISO domain 
anymore.  I am trying to clean this up now and try again.

[ovirt-users] Hosted Engine deploy failed on new HCI build

[Jayme]

Latest version of oVirt node 4.2 installed on three hosts.  I completed
successfully the cockpit gdeploy process to deploy HCI.  All of that went
well with no errors.  I then proceeded to the hosted engine deployment step
which eventually failed (log attached).

This is the current status:

--== Host 1 status ==--

conf_on_shared_storage : True
Status up-to-date  : True
Hostname   : MASKED
Host ID: 1
Engine status  : {"reason": "failed liveliness check",
"health": "bad", "vm": "up", "detail": "Up"}
Score  : 3400
stopped: False
Local maintenance  : False
crc32  : 3fa48e03
local_conf_timestamp   : 8468
Host timestamp : 8468
Extra metadata (valid at timestamp):
metadata_parse_version=1
metadata_feature_version=1
timestamp=8468 (Mon Jul 30 14:21:09 2018)
host-id=1
score=3400
vm_conf_refresh_time=8468 (Mon Jul 30 14:21:09 2018)
conf_on_shared_storage=True
maintenance=False
state=EngineStarting
stopped=False

If I do hosted-engine --console I get:

The engine VM is running on this host
Connected to domain HostedEngine
Escape character is ^]
error: internal error: cannot find character device 

does anyone know why it may have failed or what I could do to recover from
this?  I'm thinking it could have potentially failed due to some problem
with network config.  If I could get a console in to the engine VM I might
be able to fix it but that serial error above is preventing me from
reaching the vm console to diagnose further.

Log of deploy attached:

Thanks!

Yes, in the past I've used that same Dell server (for Windows Storage Spaces).
That Perc controller only allows the RAID 0 way (1 disk per RAID 0).

[ovirt-users] Unable to revive host after a reboot

[Julius Schwartzenberg]

Hi,

I recently had to shutdown my oVirt system which contains both the
engine and the host. After it came back up, the host was not able to
initialize anymore from the oVirt UI.

First it kept getting stuck in a loop with setting "ExecutingStarted:
Jul 30, 2018, 9:06:21 AMSetting Host pc331 to Non-Operational mode."

This was being repeated over and over again. It also gave this error:
Host pc331 does not comply with the cluster Default networks, the
following networks are missing on host: 'ovirtmgmt'

Even though I am using that interface (ovirtmgmt) to access the system
and 'ip addr show' shows that it's set up properly.

I tried some more things, including upgrading the host, When I do
that, the status changes to 'Installing' and later to 'Install
Failed'.

Here are the engine.log, vdsm.log and ovirt-host-deploy*.log:
https://drive.google.com/open?id=13vIUDVjPynmAK0pnFRLabDfUlG1lmkpI

Any idea what is going wrong (what I'm doing wrong) and how to solve it?

Correct no raid on the two 2tb SSDs I plan on using replica three HCI setup
with no arbiter so each host will have a copy of data

[ovirt-users] Re: up and running with ovirt 4.2 and gluster

[William Dossett]

Same here… I am using Dell R710s with 8 disks,  2 x 1TB in RAID 0 and then 6 
virtual disks, one per physical disks.  I think you have to do it that way for 
the dell perc controller to present the disk to the OS but I haven’t actually 
tried not doing that so not sure.. anyway this works.

 

This has been very informative.  

 

James has only 3 nodes, but I have 5…  I have another posting about what 
happens when I added the two additional nodes as all the disks seem to be 
locked and multipath and I can’t create bricks on them.

 

But, once I get pas that problem, if I have 5 nodes, and I am going to create 
replica datasttores with 3 disks, do I just 3 nodes for each datastore?  Is 
there any best practice for creating datastores on any 3 nodes…

 

Perhaps an example:

 

Datastore 1 -  Node1, Node2, Node3 /dev/sdb

Datastore 2 – Node2, Node3 /dev/sdc Node4 /dev/sdb

Datastore 3 -  Node3, /dev/sdd, Node4 /dev/sdc Node5 /dev/sda

 

Does that make sense?  Or is there a better way?

 

Thanks to everyone for helping me on this, much appreciated.

 

Bill

[ovirt-users] Re: up and running with ovirt 4.2 and gluster

[Jayme]

That was the intention but I'm unclear as to which is the better approach.
I intended to host all VM related data including OS on the data volumes
(split between data on sdb and data2 on sda).. but now it sounds like doing
VM os disks on a separate volume could be a better approach after reading
this e-mail chain, as I do intend to setup georeplication disaster recovery
at some point and it might be nice to have the flexibility to only
georeplicate the vm data and not OS disks data.

If I were to set it up the other way, i.e. using vmstore to host OS disks
would it be recommended to create a VMSTORE on each device, like this for
example?

ENGINE = SDA (device 1) = 100gb

DATA = SDB (device 2) = 1200gb
DATA2 = SDA (device 1) = 1100gb

VMSTORE = SDA (device 1) = 500gb
VMSTORE2 = SDB (device 2) = 500gb

500gb may be a bit overkill here but you get the point.

 It's nice to know someone else out there has these questions as well.
 What I'd really like confirmation on is basically this:  In a JBOD oVirt
 HCI configuration with multiple disk devices per host node is it possible
 to have just one data volume or is it necessary to create multiple data
 volumes (one or more per each physical disk you want to store vm data on)?
  Meaning if I had 4 JBOD disks in each node and I wanted VM data to be
 stored and accessed on all 4 would I need to create 4 different data
 volumes (one per disk).  And if so would they have to have unique names and
 brick dirs/mount points?

I assume the vmstore (instead of data volume) would be the "preferred" 
destination for storing ISOs?

Looks good. I'm assuming you're using VMStore to host ISOs and not VM OS
disks?

Ok, thanks for the heads up.
I've been setting up my VMs with a single disk.

[ovirt-users] Re: up and running with ovirt 4.2 and gluster

[Jayme]

Hello,

Thanks for the feedback.  I don't "need" to create only one data domain,
I'm more or less trying to confirm whether or not it is proper to configure
multiple data domains or if I was mis-understanding the setup procedure.

So if I am correct, you are saying that if I have 2 JBOD storage devices in
each host that best practice is for each of those to have its own data
volume?

Like this for example:

ENGINE = SDA (device 1) = 100gb
DATA = SDB (device 2) = 2000gb
VMSTORE = SDA (device 1) = 500gb
DATA2 = SDA (device 1) = 1100gb

That would allocate all the space available on both of my drives (2x2tb)
and create two data volumes, a 2TB one on SDB device and a 1.1TB on SDA
device.  SDA device would also be used for engine and vmstore volumes.  Is
this correct configuration for two JBOD devices per host?

This is to ease setup of data backup. As VMs can be recreated from
template/ISOs and only the application data can be backed up.

The guideline is to create 1 brick per device and this is what the Cockpit
UI implements. When you group together all 4 JBOD disks to form 1 brick  -
you're essentially setting up 1 large brick without any hardware RAID
protection for the disks. Any 1 of the disk failure would cause the entire
brick to be unavailable and would require healing the whole brick. So if
you had 4 1TB disks, you would end up creating a 4TB brick which needs
healing - not the best of scenarios.

Why do you need to create 1 data storage domain instead of multiple?

Sahina,

So "best practice" is for every VM to have 2 disks: 1 for the operating system 
& 1 for the data?

[Jayme]

It's nice to know someone else out there has these questions as well.  What
I'd really like confirmation on is basically this:  In a JBOD oVirt HCI
configuration with multiple disk devices per host node is it possible to
have just one data volume or is it necessary to create multiple data
volumes (one or more per each physical disk you want to store vm data on)?
 Meaning if I had 4 JBOD disks in each node and I wanted VM data to be
stored and accessed on all 4 would I need to create 4 different data
volumes (one per disk).  And if so would they have to have unique names and
brick dirs/mount points?

yes it is possible, unless you enabled `Delete protection` checkbox while

Then just detach the VM from the pool and delete it afterwards.

[ovirt-users] Re: Upgrade from 4.1 to 4.2 failing - SQL Issues

[p . staniforth]

Hi Sven,
 to test I created a new VM with a new hostname and fake IP 
addresses in /etc/hosts for the oVirt hosts/nodes so it won't interfere with 
the real hosts. I then did a full restore from backup and an engine rename. 
This leaves you with oVirt system but the no storage or hosts. There are a lot 
of errors in the logs and events but you can use it to test the engine upgrade, 
etc.

Hi Josá, 

yes it is possible, unless you enabled `Delete protection` checkbox while 
creating the pool. 
Then just detach the VM from the pool and delete it afterwards.

In order to import an existing storage domain, the old domain should be
removed first.
If you need to import just a single vm/disk, you can use the upload flow:
https://ovirt.org/develop/release-management/features/storage/backup-restore-disk-snapshots/
Or, if relevant, use the backup API integration:
https://www.ovirt.org/develop/release-management/features/storage/backup-restore-api-integration/

I cannot even attach snapshot volume.
Disks scanning is available only for attached storage domains.

[ovirt-users] Re: VM User with UserRole missing permissions to activate console and other actions

[Callum Smith]

Dear Michal,

We’re on the latest release version, 4.2.4.

VM Permissions are UserRole and no others.

All of the forbidden issues could be misleading, but along with the server-side 
permissions issues that leads me to believe it could be a combination of both 
the issue you suggest and another one underlying?

We have to go with full release versions ideally as the ovirtengine is in 
production, I'd rather avoid the master branch version.

sure, so which ones do you have?
both ovirt-engine and ovirt-web-ui
Also please add what all permissions you have set on that VM, and which user 
tries to access it

Callum

Callum,

If you are seeing the error when opening the console from VM Portal (web-ui), 
this sounds a lot like issue [1].  A patch against the ovirt REST api was done 
to help mitigate some errors that should not happen.  I'll take a look to see 
how it is working in the current master snapshot of ovirt-engine and VM Portal.

What version of oVirt are you using?

[ovirt-users] Re: template disk attribute in version 4 restapi

[like...@cs2c.com.cn]

Hi, Idan. 
I have one more question. There is no diskattachments link for template in 
export storage domain. 
So i want to add the diskattachments link for it. I tried to read the source 
code in ovirt-engine project.
BackendStorageDomainTemplateResource defines some methods of 
StorageDomainTemplate. 
It implements the interface 
org.ovirt.engine.api.resource.StorageDomainTemplateResource.
But i can't find where is the location of 
org.ovirt.engine.api.resource.StorageDomainTemplateResource.
Could you please tell me where i can find the source code of 
StorageDomainTemplateResource?

Thanks

Regards.

Thanks a lot. You're right, something is indeed wrong. From your reply, i

find that my colleague added ENGINE_API_DEFAULT_VERSION=3 in the configuration 
file for his own experiment, but he didn't notify us. Now i delete the 
configuration item, everything is fine.

template.
Can you say what you do have under /ovirt-engine/api/templates/?
This is the output I get in 4.1.9 under 
ovirt-engine/api/templates/----/ (pasting only 
the links):

Actually, it was added back in oVirt 4.0.
What happens when you try to GET from 
/ovirt-engine/api/templates//diskattachments?
Do you get an empty list of attachments or an error (404 not found)?

Hi,

The bootable attribute was moved, along with a few more attributes, to be under 
a specific diskattachment, as it is an attribute of the relationship between a 
disk and the specific VM it is attached to, rather than a disk (which can be 
floating, or attached to more than one VM).
I am not sure that I understand the question. A template does have 
diskattachments under /ovirt-engine/api/templates//diskattachments.
Which engine's version are you using?

Idan

Hi All,

In the restapi of version 3, there is bootable attribute  in disk. But in 
version 4, the bootable attribute is removed from disk. For vm i can get 
bootable attribute from diskattachment. But there is no diskattachment in 
template. So, is there any way in the restapi of version 4 that i can know if 
the disk of the template is bootable or not?

Thanks

Regards.

Engine volume = the Hosted Engine storage domain
vmstore volume = the storage domain hosting the OS disks for the VMs
data volume = the storage domain hosting the data disks of the VMs

This was designed such that when setting up for disaster recovery, you need
to set up remote backup only for the data disks

Please let us know /contribute to improving the documentation if this was
not clear

Did you create a brick from the UI or using CLI on the hosts. Can you check
where the bricks are mounted?
If it's mounted at /gluster_bricks - the bricks should be listed in the New
volume screen

I think that your issue comes from here.
On a clean system you have LANG=en_US.UTF-8 and you probably initially deployed 
oVirt 4.1 with postgres 9.2 with that but now you set just LANG=en_US and so 
postgres initdb is trying to honor that creating 9.5 template0 and template1 
without utf-8 support and so the upgrade from 9.2 utf-8 to 9.5 without utf-8 is 
failing.
I'd suggest to set LANG=en_US.UTF-8 and then try again the upgrade procedure 
from engine-setup.

Just tried this and it’s still failing. Language seems to be set properly:
[root@ovirt-engine ~]# localectl  status

I know for sue that a nested kvm env over vmware esxi is still problematic;

[ovirt-users] Re: oVirt 4.2.5.1-1.el7 JSON-RPC statistics error

[Maton, Brett]

I rebooted the server that was failing last week and haven't seen the error
since.

 Yes, copying it from another host with mom version 0.5.12 is enough.

 I'm not sure why it was not installed. The file is in the rpm.

 Hi,

 Looking at MOM logs, the problem seems to be that MOM is configured
 to use 'vdsmjsonrpcclient' module to communicate with vdsm, but it
 cannot find this module, probably because it is an older version.

 Updating MOM to version 0.5.12 should fix it.


 Regards,
 Andrej
