Re: Storage domain 'Inactive' but still functional
by Martijn Grendelman
Hi!
Thanks. Like I wrote, I have metadata backups from /etc/lvm/backup and -/archive, and I also have the current metadata as it exists on disk. What I'm most concerned about, is the proposed procedure.
I would create a backup of the VG, but I'm not sure what would be the most sensible way to do it. I could make a new iSCSI target and simply 'dd' the whole disk over, but that would take quite some time (it's 2,5 TB) and there are VMs that can't really be down for that long. And I'm not even sure that dd'ing the disk like that is a sensible strategy.
Moving disks out of the domain is currently not possible. oVirt says 'Source Storage Domain is not active'.
Thanks,
Martijn.

Can you check the /etc/lvm/backup and /etc/lvm/archive on your SPM host (check the other hosts, just in case you find anything useful) ?
Usually LVM makes backup of everything.
I would recommend you to:
1. Create a backup of the problematic VG
2. Compare the backup file and a file from backup/archive folders for the same VG
Check what is different with diff/vimdiff . It might give you a clue.
I had some issues (non-related to oVirt) and restoring the VG from older backup did help me .Still ,any operation on block devices should be considered risky and a proper backup is needed.
You could try to move a less important VM's disks out of this storage domain to another one.
If it succeeds - then you can evacuate all VMs away before you can start "breaking" the storage domain.

Hi,
For the first time in many months I have run into some trouble with oVirt (4.3.4.3) and I need some help.
Yesterday, I noticed one of my iSCSI storage domains was almost full, and tried to move a disk image off of it, to another domain. This failed, and somewhere in the process, the whole storage domain went to status 'Inactive'.

The thing is, the domain is still functional on all my hosts. It carries over 50 disks, and all involved VMs are up and running, and don't seem to have any problems. Also, 'iscsiadm' on all hosts seems to indiciate that everything is fine with this specific target and reading from the device with dd, or getting its size with 'blockdev' all works without issue.
When I try to reactivate the domain, these errors are logged:

I need help getting this storage domain back online. Can anyone here help me? If you need any additional information, please let me know!
It appears the VG metadata is corrupt:
/dev/mapper/23536316636393463: Checksum error at offset 2748693688832
Couldn't read volume group metadata from /dev/mapper/23536316636393463.
Metadata location on /dev/mapper/23536316636393463 at 2748693688832 has invalid summary for VG.
Failed to read metadata summary from /dev/mapper/23536316636393463
Failed to scan VG from /dev/mapper/23536316636393463
Is this fixable? If so, how?
So, I have found some information online, that suggests that PV metadata can be fixed by recreating the PV label using the correct PVID and a backup of the LVM metadata, like so:
pvcreate -u <pv_uuid> --restorefile <lvm_metadata_backup> /dev/mapper/23536316636393463
Now I have the following two files:
* An LVM metadata backup of yesterday 10:35, about 6 hours before the problem occurred.
* The actual metadata found on the PV at offset 2748693688832 (obtained with hexedit on the block device).
These are largely the same, but there are differences:
* seqno = 1854 in the backup and 1865 in the actual metadata.
* 3 logical volumes that are not present in the backup, but are in the actual metadata. I suspect that these are related to snapshots that were created for live storage migration, but I am not sure. In any case, I did NOT create any new disk images on this domain, so that can't be it.
Now, support I wanted to try the 'pvcreate' route, then:
* what would be the chances of success? Is this procedure at all advisable, or is there an alternative?
* which restore file (1854 or 1865) should I use for the restore?
* can I do this while the VG is in use? I tried running the command without --force, and it said 'Can't open /dev/mapper/23536316636393463 exclusively. Mounted filesystem?'. I didn't dare to try it with '--force'.
I could really use some advice on how to proceed. This are about 36 VMs that have one or more disks on this domain. I could bring them down, although doing so for extended amounts of time would be problematic. I want to be careful, obviously, especially since the actual storage doesn't seem to be impacted at this time. The VMs are all still running without issue, and if I'm about to embark on a dangerous journey that could cause data loss, I need a contingency / recovery plan.
Hoping someone can help...
Best regards,
Martijn Grendelman

Storage domain 'Inactive' but still functional
by Martijn Grendelman
Hi,
For the first time in many months I have run into some trouble with oVirt (4.3.4.3) and I need some help.
Yesterday, I noticed one of my iSCSI storage domains was almost full, and tried to move a disk image off of it, to another domain. This failed, and somewhere in the process, the whole storage domain went to status 'Inactive'.

assign vm traffic to a physical NIC and Storage traffic to another NIC
by Erick Perez
Hi,
fresh install
I have created a network called "storage" and another called "vms" and both have vlan 102 tag. Only the "vms" network have the check on "vm network".
then on Compute---Hosts---hvm001---setup_host_network
physical nic enp3s0f0 has ovirtmgmt and vms networks defined
physical nic enp3s0f1 has storage network defined
Question is how do I tell ovirt that I want the STORAGE traffic to use enp3s0f1 ?
I am using NFS data domains and I cannot find a place to tell the network/physical nic my NFS traffic should use.
thanks,

LDAP Group issue with rfc2307bis
by Timmi
Hi oVirt List,
I'm currently working on my new oVirt setup and want to integrate it
into our LDAP server.
Accounts are working fine but I have problems to get the groups working
correctly.
The LDAP server is base on ClearOS which is using the rfc2307bis setup.
Means I don't have MemberOf inside my users. The user DN is as Member
inside the group.
I manage that oVirt is able to read the groups while overwriting:
search.rfc2307-resolve-groups-memberUid.search-request.filter =
&(objectClass=posixGroup)(memberUid=${seq:_rfc2307_uid_encoded})
with
search.rfc2307-resolve-groups-memberUid.search-request.filter =
&(objectClass=posixGroup)(member=${seq:_rfc2307_dn})
This is working absolutely fine for my admin group in "Administrator
Portal". I can asign the group to the system permission "SuperUser" and
everything is working great.
My problem is with the "VM Portal" I have assigned "PowerUser" rights to
a quota and it is possible to login but I receive the following error in
the engine.log.
2019-07-18 07:38:12,317+02 ERROR
[org.ovirt.engine.core.bll.GetPermissionsForObjectQuery] (default
task-5) [a6828f8b-8ded-422f-a216-5e5406d7bf20] Query execution failed
due to insufficient permissions.
2019-07-18 07:38:12,319+02 ERROR
[org.ovirt.engine.api.restapi.resource.AbstractBackendResource] (default
task-5) [] Operation Failed: query execution failed due to insufficient
permissions.
I'm able to see the group permission in the user details. So I guess
that something is already working. But I guess the error is preventing
me to have the "create VM" button on the "VM Portal".
Would be great if someone could help me out.
I'm running the latest 4.3.4 version.
Best regards

Support and suggestions for 10/25 GbE cards
by Gianluca Merlo
Hello everyone,
I am in the hardware selection phase for an oVirt cluster which has a
requirement for 10/25 GbE connectivity. Does anyone have any advice on
which adapters are better supported and working on oVirt Node? The choice I
have is between:
- Intel XXV710
- Mellanox ConnectX-4
It is my first foray into this tier of connectivity, so pardon the naivety
of the question. I would just like to hear suggesions from the experience
any of you may have had in the field, so I can be better prepared and know
which kind of problems I may run into, and if choosing a specific card over
the other can spare me some.
Thank you in advance for your help

hosted engine, Hyperconverged recovery
by William Kwan
Hi,
I need some direction to make sure we won't make more mistake in recovering a 3-node self hosted engine with Gluster.
Someone carelessly, very, wiped out the first few MB of the LVM PV on one node. We changed the quorum and brought up the Gluster and oVirt. We ran vgcfgrestore on the 'bad node' and we can run pvscan, vgscan and lvscan to see the LV's.
What should I do next to prevent more damage or corrupt the glusterfs on the other two nodes?
Will this work? mkfs the LV's bring up gluster run gluster sync <goodNode>?
ThanksWill

VM says paused, but does not appear to be.
by Jacob Green
I have a Fibre Channel back end for my oVirt cluster, and one of my
VMS is saying "paused due to lack of storage space", however I can
confirm that the back end storage has plenty of space and the VM itself
does not appear to be paused. I can SSH the VM and perform tasks on the
VM. So I am trying to figure out why it would say that, and how to clear
it. Also have 20 something other VMS on this cluster and no errors like
this on those. I am running engine 4.3.3.7-1.el7
Also I do not fully understand this chart, what I can tell you is that
the top storage domain is my Fibre Channel storage, and it has plenty of
available space, 35%-40% free
And lastly this is what a df -h looks like on the given VM.
If anyone has some insight on to what might cause this let me know and
ill chase it down.
Thank you

Re: Hardware Used
by Strahil
As far as I know several orgs are using AMD Ryzen CPUs with oVirt.
Ryzen CPUs are quite nice from price/performance perspective.
