Current status of Ceph support in oVirt (2019)?
by victorhooi＠yahoo.com 03 Dec '19

03 Dec '19

Hi, I currently have a 3-node HA cluster running Proxmox (with integrated Ceph). oVirt looks pretty neat, however, and I'm excited to check it out. One of the things I love about Proxmox is the integrated Ceph support. I saw on the mailing lists that there is some talk of Ceph support earlier, but it was via OpenStack/Cinder. What exactly does this mean? 1. Does this require you to install OpenStack, or will a vanilla Ceph installation work? 2. Is it possible to deploy Ceph on the same nodes that run oVirt? (i.e. is a 3-node oVirt + Ceph cluster possible?) 3. Is there any monitoring/management of Ceph from within oVirt? (Guessing no?) 4. Are all the normal VM features working yet, or is this planned? 5. Is making Ceph a first-class citizen (like Gluster) on oVirt on the roadmap? Thanks, Victor https://www.reddit.com/r/ovirt/comments/ci38zp/ceph_rbd_support_in_ovirt_fo…

oVirt nodes not responding
by Tim Herrmann 03 Dec '19

03 Dec '19

Hi everyone, we have an oVirt-Cluster with 5 nodes and 3 of them provide the storage with GlusterFS and replica 3. The cluster is running 87 VMs and has 9TB storage where 4TB is in use. The version of the oVirt-Engine is 4.1.8.2 and GlusterFS is 3.8.15. The servers are running in a HP bladecenter and are connected with 10GBit to each other. Actually we have some problems that all ovirt nodes periodically won't respond in the cluster with the following error messages in the oVirt webinterface: VDSM glustervirt05 command GetGlusterVolumeHealInfoVDS failed: Message timeout which can be caused by communication issues Host glustervirt05 is not responding. It will stay in Connecting state for a grace period of 68 seconds and after that an attempt to fence the host will be issued. Host glustervirt05 does not enforce SELinux. Current status: PERMISSIVE Executing power management status on Host glustervirt05 using Proxy Host glustervirt02 and Fence Agent ilo4:xxx.xxx.xxx.xxx. Manually synced the storage devices from host glustervirt05 Status of host glustervirt05 was set to Up. In the vdsm logfile I can find the following message: 2019-11-26 11:18:22,909+0100 WARN (vdsm.Scheduler) [Executor] Worker blocked: <Worker name=jsonrpc/7 running <Task <JsonRpcTask {'params': {u'volumeName': u'data'}, 'jsonrpc': '2.0', 'method': u'GlusterVolume.healInfo', 'id': u'2e86ed2c- 3e79-42c1-a7e4-c09bfbfc7794'} at 0x7fb938373190> timeout=60, duration=180 at 0x316a6d0> task#=2859802 at 0x1b70dd0> (executor:351) And I figured out, that the gluster heal info command takes very long: [root@glustervirt01 ~]# time gluster volume heal data info Brick glustervirt01:/gluster/data/brick1 Status: Connected Number of entries: 0 Brick glustervirt02:/gluster/data/brick1 Status: Connected Number of entries: 0 Brick glustervirt03:/gluster/data/brick2 Status: Connected Number of entries: 0 real 3m3.626s user 0m0.593s sys 0m0.559s A strange behavier is also that there is one virtual machine (a postgresql database) which stops running unexpectedly every one or two days ... The only thing that has been changed on the vm in the least past was a resize of the disk. VM replication-zabbix is down with error. Exit message: Lost connection with qemu process. And when we add or delete a larger disk with approximately 100GB in glusterfs, the glusterfs cluster freaks out won't respond anymore. This also results in paused VMs ... Has anyone an idea what could cause such problems?

Re: Scenario: Ovirt-engine on hardware and recovery
by Strahil 03 Dec '19

As this is not a VM, you won't have to worry about putting 1 host in maintenance. I make backups lile this: engine-backup --mode=backup --scope=all --file=/root/engine-bkp-empty-ovirt1-ver4.3.7-rc4--2019-11-30 --log=/var/log/engine-backup.log I'm specifying the host that will be used for restore, which is needed when the engine is VM. In your bare-metal case - you just need to recover the OS/harfware and restore from backup.

Re: host failed to attach one of the storage domains attached to it
by Strahil 03 Dec '19

03 Dec '19

Hi Daniel, The hosts go to unresponsive mode as one of the gluster volumes cannot be mounted. Verify that all host can mount (over /mnt) all gluster volumes. If they do, just set the hosts into maintenance and then activate them.

NFS Storage Domain on OpenMediaVault

I have a clean install with openmediavault as backend NFS and cannot get it to work. Keep getting permission errors even though I created a vdsm user and kvm group; and they are the owners of the directory on OMV with full permissions.

host failed to attach one of the storage domains attached to it
by Daniel Menzel 02 Dec '19

02 Dec '19

Dear all, after a GlusterFS reboot of two servers out of three (and thus a loss of quorum) by an admin we've got strange problems: 1. The hosted engine and one export work perfectly fine. (Same three servers!) 2. Another export (main one) seems to be fine within GlusterFS itself. But: When we activate this domain most of the hosts go into "non operational" with the subject's error message. As soon as we deactivate this domain all those hosts come back online. Strange thing: The GlusterFS export seems to be mounted on the SPM. Does anyone know what could have happened and how to fix that? Kind regards Daniel

Overt Networking VM not pinging
by Vijay Sachdeva 02 Dec '19

02 Dec '19

Dear Community, I have installed Ovirt Engine 4.3 and Ovirt Node 4.3. Node got successfully added to engine and setup host network also done. When trying to ping host using “ovirtmgmt” as vNic profile for a VM, it is not even able to ping it’s host or any other machine on that same network. Also added a VLAN network which is passed via same uplink of Node interface where “Ovirtmgmt” is passed, that is also not working. Although this vnet is vnic type is VirtIO and state shows “UNKNOWN”, would this be a problem? Any help would be highly appreciated.
