CLUSTER_CANNOT_DISABLE_GLUSTER_WHEN_CLUSTER_CONTAINS_VOLUMES

29 Mar '19

Hi, I updated ou oVirt cluster to 4.3.2 and when i try to update the cluster version to 4.3 i get the following error: CLUSTER_CANNOT_DISABLE_GLUSTER_WHEN_CLUSTER_CONTAINS_VOLUMES So far I remember I could update the cluster version to 4.2 without having to stop everything. I've searched around about this error but couldn't find anything. The engine log says: 2019-03-20 14:33:28,125+01 INFO [org.ovirt.engine.core.bll.UpdateClusterCommand] (default task-59) [c93c7f4f-b9a3-4e10-82bf-f8bbda46cc87] Lock Acquired to object 'EngineLock:{exclusiveLocks='[25682477-0bd2-4303-a5fd-0ae9adfd276c=TEMPLATE]', sharedLocks='[119fad69-b4a2-441f-9056-354cd1b8a7aa=VM, 1f696eca-c0a0-48ff-8aa9-b977345b5618=VM, 95ee485d-7992-45b8-b1be-256223b5a89f=VM, 432ed647-c150-425e-aac7-3cb5410f4bc8=VM, 7c2646b1-8a4c-4618-b3c9-dfe563f29e00=VM, 629e40c0-e83b-47e0-82bc-df42ec310ca4=VM, 2e0741bd-33e2-4a8e-9624-a9b7bb70b664=VM, 136d0ca0-478c-48d9-9af4-530f98ac30fd=VM, dafaa8d2-c60c-44c8-b9a3-2b5f80f5aee3=VM, 2112902c-ed42-4fbb-a187-167a5f5a446c=VM, 5330b948-f0cd-4b2f-b722-28918f59c5ca=VM, 3f06be8c-8af9-45e2-91bc-9946315192bf=VM, 8cf338bf-8c94-4db4-b271-a85dbc5d6996=VM, c0be6ae6-3d25-4a99-b93d-81b4ecd7c9d7=VM, 8f4acfc6-3bb1-4863-bf97-d7924641b394=VM]'}' 2019-03-20 14:33:28,214+01 WARN [org.ovirt.engine.core.bll.UpdateClusterCommand] (default task-59) [c93c7f4f-b9a3-4e10-82bf-f8bbda46cc87] Validation of action 'UpdateCluster' failed for user xxxx@yyy.

virsh edit vm not saving after reboot
by Dev Ops 29 Mar '19

29 Mar '19

I am trying to get Cisco ISE installed into Ovirt. I was told I needed to do a virsh edit on the vm and change a line in the smbios settings. This is all simple enough. After a reboot or shutdown/restart the settings revert back to what they were before. A dump of the XML in fact shows the original settings that I had changed. Since I can't edit the file while the VM is off I am not sure how to save this config change. My issue is similar to this: https://access.redhat.com/discussions/2720821 I have been reading and digging around with no luck. I just can't seem to make this change static. Thanks!

28 Mar '19

Hello, everyone. I had a question on how to create a data domain in the best way. for example, I have a FCP device and there's a lot of hdds and ssds in that device. I ceate 2 luns. one consisting of HDDs and the other consisting of SSDs. I want to make some normal vms run in the lun with hdd and some vms (such as DB) run in the lun with ssd. so, shoud I create one data domain with the 2 luns. or shoud I create 2 difference data domains, and every data domain with a single lun in it? thanks. yours Adam

User permissions needed to clone template disk
by Wood Peter 27 Mar '19

27 Mar '19

Hi, Users have PowerUserRole permissions on the cluster and the storage objects. Also TemplateCreator role on the Datacenter. When users create VMs from templates there is no option to clone the disk and create independent VM disk. The resource allocation section is not visible at all. What permissions should I give users so they can clone the disk when creating a VM from a template? Using oVirt 4.2.8.2-1.el7 Thank you, -- Peter

VM disk corruption with LSM on Gluster
by Sander Hoentjen 27 Mar '19

27 Mar '19

Hello, tl;dr We have disk corruption when doing live storage migration on oVirt 4.2 with gluster 3.12.15. Any idea why? We have a 3-node oVirt cluster that is both compute and gluster-storage. The manager runs on separate hardware. We are running out of space on this volume, so we added another Gluster volume that is bigger, put a storage domain on it and then we migrated VM's to it with LSM. After some time, we noticed that (some of) the migrated VM's had corrupted filesystems. After moving everything back with export-import to the old domain where possible, and recovering from backups where needed we set off to investigate this issue. We are now at the point where we can reproduce this issue within a day. What we have found so far: 1) The corruption occurs at the very end of the replication step, most probably between START and FINISH of diskReplicateFinish, before the START merge step 2) In the corrupted VM, at some place where data should be, this data is replaced by zero's. This can be file-contents or a directory-structure or whatever. 3) The source gluster volume has different settings then the destination (Mostly because the defaults were different at creation time): Setting old(src) new(dst) cluster.op-version 30800 30800 (the same) cluster.max-op-version 31202 31202 (the same) cluster.metadata-self-heal off on cluster.data-self-heal off on cluster.entry-self-heal off on performance.low-prio-threads 16 32 performance.strict-o-direct off on network.ping-timeout 42 30 network.remote-dio enable off transport.address-family - inet performance.stat-prefetch off on features.shard-block-size 512MB 64MB cluster.shd-max-threads 1 8 cluster.shd-wait-qlength 1024 10000 cluster.locking-scheme full granular cluster.granular-entry-heal no enable 4) To test, we migrate some VM's back and forth. The corruption does not occur every time. To this point it only occurs from old to new, but we don't have enough data-points to be sure about that. Anybody an idea what is causing the corruption? Is this the best list to ask, or should I ask on a Gluster list? I am not sure if this is oVirt specific or Gluster specific though. Kind regards, Sander Hoentjen

Gluster VM image Resync Time
by Indivar Nair 27 Mar '19

27 Mar '19

Hi All, We are planning a 2 + 1 arbitrated mirrored Gluster setup. We would have around 50 - 60 VMs, with an average 500GB disk size. Now in case one of the Gluster Nodes go completely out of sync, roughly, how long would it take to resync? (as per your experience) Will it impact the working of VMs in any way? Is there anything to be taken care of, in advance, to prepare for such a situation? Regards, Indivar Nair

oVirt Roles and Permissions
by Wood Peter 27 Mar '19

27 Mar '19

Hi, I'm trying to setup oVirt 4.2.8.2-1.el7 based on a few simple requirements: Users should be able to: 1) reate new VMs 2) create VMs from templates 2a) Ability to clone the template disk to create a VM independent of the template 3) create templates 4) view only the VMs they have permissions to work with i.e. UserVmManager role assign to them This was all possible through the "User Portal" in version 3 (3.6 is what I had). The new "VM Portal" doesn't allow users to create templates. In order to satisfy (3) users must login to the Admin Portal. This is OK but I created a new Admin role with just login permissions and users can see all VMs in the cluster. I assume a filter can be created but in general I don't want them to have that much visibility. I can probably get away without (3) but I still can figure out how to do (2a) using "VM Portal". All VMs created from a template are dependent on that template. Even if the template is optimized for Server. How do I accomplish this? Thank you in advance for any suggestions. -- Peter

Re: Using NFS on Gluster
by Strahil 26 Mar '19

26 Mar '19

Hi Indivar, You can do that , but is complicated. First, I would recommend you to use either replica 3 or replica 3 arbiter 1 cluster volumes. Second , you have 2 options - to use NFS provided by Cluster Cluster ,but this is deprecated and you will have to migrate from that option once it get's completely removed. Third option is to use CTDB to fail over your floating VIP and to start NFS-Ganesha. The benefit of using NFS-Ganesha is that it uses libgfapi and connects to all cluster nodes simultaneously providing accumulated performance.

Hello, we are using oVirt-4.2.8 and I have created a logical network using the ovn-network-provider, I haven't configured it to connect to a physical network. I have 2 VMs running on 2 hosts which can connect to each other this logical network. The only connection between the hosts is over the ovirtmgmt network so presumably the traffic is using this?

Using NFS on Gluster
by Indivar Nair 26 Mar '19

26 Mar '19

Hi All, We would like to set up a 2 node mirrored Gluster Storage using the ovirt installation tools, but use it as an NFS storage. We want to do this for 2 reasons - 1. We have a high-speed link between both the Gluster Nodes which we would like to use for brick replication rather than ovirt node's 1G link 2. We have fast SSD disks on the ovirt nodes which we would like to use for local NFS Caching (FS Caching) on the VM Images. In short, we would like to manage Gluster stroage using the ovirt web interface, but access the Gluster storage as an NFS Server. How can we do this? Thanks. Regards, Indivar Nair

For backup, you can use anything that works for KVM, but the hard part is to get the configuration of each VM. If the VM is running, you can use 'virsh dumpxml domain' to get the configuration of the running VM, but this won't work for VM that are off. Why firewalld was not stopped - my guess is a rare bug that is hard to reproduce.

Re: OVirt Gluster Fail

Hi Andrea, The cluster volumes might have sharding enabled and thus files larger than shard size can be recovered only via cluster. You can try to restart gluster on all nodes and force heal: 1. Kill gluster processes: systemctl stop glusterd /usr/share/glusterfs/scripts/stop-all-gluster-processes.sh 2. Start gluster: systemctl start glusterd 3. Force heal: for i in $(gluster volume list); do gluster volume heal $i full ; done sleep 300 for i in $(gluster volume list); do gluster volume heal $i info summary ; done Best Regards, Strahil NikolovOn Mar 23, 2019 13:51, commramius(a)tiscali.it wrote: > > During maintenance of a machine the hosted engine crashed. > At that point there was no more chance of managing anything. > > The VMs have paused, and were no longer manageable. > I restarted the machine, but one point all the bricks were no longer reachable. > > Now I am in a situation where the engine support is no longer loaded. > > The gluster sees the peers connected and the services turned on for the various bricks, but fails to heal the messages that I find for each machine are the following > > # gluster volume heal engine info > Brick 192.170.254.3:/bricks/engine/brick > > . > . > . > > Status: Connected Number of entries: 190 > > Brick 192.170.254.4:/bricks/engine/brick > Status: Il socket di destinazione non è connesso > Number of entries: - > > Brick 192.170.254.6:/bricks/engine/brick > Status: Il socket di destinazione non è connesso > Number of entries: - > > this for all the bricks (some have no heal to do because the machines inside were turned off). > > In practice all the bricks see only localhost as connected. > > How can I restore the machines? > Is there a way to read data from the physical machine and export it so that it can be reused? > Unfortunately we need to access that data. > > Someone can help me. > > Thanks Andrea > _______________________________________________ > Users mailing list -- users(a)ovirt.org > To unsubscribe send an email to users-leave(a)ovirt.org > Privacy Statement: https://www.ovirt.org/site/privacy-policy/ > oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ > List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/EOIY7ZU4GOEMR…

How to create a template from VM Portal
by Wood Peter 26 Mar '19

26 Mar '19

Hi, How do I create a template from a VM in "VM Portal"? I'm using version 4.2.8.2 and I don't see the option to convert a VM to a template anywhere. The documentation refers to the Administration Portal interface. Is it possible to create a template from the "VM Portal" or one must login to "Administration Portal"? Any help would be appreciated. Thank you, -- Peter
