oVirt Storage quota questions
by Vrgotic, Marko 27 Feb '20

27 Feb '20

Dear oVirt, My platform is running SHE oVirt version 4.3.8. Why is my StorageQuota consumption still showing “ 0 out of 3700” ? Did I forget something? [A screenshot of a cell phone Description automatically generated] I have setup storage quota “StorageQuota” for one of domains. It has 4400GB actual storage. * Quota is set to 3700GB. * Treshold for Quota is 85% and Grace is set to 110%. * Datacenter Quota is set to Enforced * The template image has been changed from Default to StorageQuota * I see that Vms created from Template are automatically assigned StorageQuota To present the following situation in screenshots: * Actual Quota: [A screenshot of a social media post Description automatically generated] * VMs (more than on the screenshot) which have the StorageQuota assigned: [A screenshot of a social media post Description automatically generated] * Templates which have the StorageQuota assigned [cid:image004.png@01D5ED57.6C02ACF0] Kindly awaiting your reply. Additionally – is there an easy&safe way to update all running VMs quota? ----- kind regards/met vriendelijke groeten Marko Vrgotic Sr. System Engineer @ System Administration ActiveVideo o: +31 (35) 6774131 e: m.vrgotic(a)activevideo.com<mailto:m.vrgotic@activevideo.com> w: www.activevideo.com<http://www.activevideo.com> ActiveVideo Networks BV.

Storage performance comparison (gluster vs FC)
by Rik Theys 26 Feb '20

26 Feb '20

Hi, We currently use oVirt on two hosts that connect to a shared storage using SAS. In oVirt this is a "FC" storage domain. Since the warrantly on the storage box is ending, we are looking at alternatives. One of the options would be to use gluster and use a "hyperconverged" setup where compute and gluster are on the same hosts. We would probably end up with 3 hosts and a "replica 3 arbiter 1" gluster volume. (Or is another volume type more recommended for this type of setup?) I was wondering what the expected performance would be of this type of setup compared to a shared storage over FC. I expect the I/O latency of gluster to be much higher than the latency for the SAS connected storage box? Has anybody compared these storage setups?

oVirt 4.3.8 spice console not working after vm migration
by Gianluca Cecchi 26 Feb '20

26 Feb '20

Hello, I'm registering problems with spice console session that remains stuck and not working after vm migration. Tried with 7.6 and 8.1 based virtual machines. The client is an updated Fedora 31 system. Using lsof -Pp pid command I don't see any tcp sessione opened Making the same when session is connected before migration: remote-vi 8013 g.cecchi 21u IPv4 243582 0t0 TCP localhost.localdomain:35218->10.4.192.32:5902 (ESTABLISHED) remote-vi 8013 g.cecchi 22u IPv4 248960 0t0 TCP localhost.localdomain:35226->10.4.192.32:5902 (ESTABLISHED) remote-vi 8013 g.cecchi 23u IPv4 248961 0t0 TCP localhost.localdomain:35228->10.4.192.32:5902 (ESTABLISHED) remote-vi 8013 g.cecchi 24u IPv4 248962 0t0 TCP localhost.localdomain:35230->10.4.192.32:5902 (ESTABLISHED) Right after migration I see only the close wait of the previous but not a new one with the ip of the destination host: remote-vi 8013 g.cecchi 21u IPv4 243582 0t0 TCP localhost.localdomain:35218->10.4.192.32:5902 (CLOSE_WAIT) And after a few seconds none. Also, closing the blocked spice window doesn't work: it becomes gray with in the middle "Waiting for display 1..." and I have to "kill -9 the remote-viewer process. Strangely the reverse works. After force closing spice console and connecting to the remote and making migrate reverse, the spice console session keeps working... The hosts have same versions of components: OS Version: RHEL - 7 - 7.1908.0.el7.centos OS Description: CentOS Linux 7 (Core) Kernel Version: 3.10.0 - 1062.12.1.el7.x86_64 KVM Version: 2.12.0 - 33.1.el7_7.4 LIBVIRT Version: libvirt-4.5.0-23.el7_7.5 VDSM Version: vdsm-4.30.40-1.el7 SPICE Version: 0.14.0 - 7.el7 GlusterFS Version: [N/A] CEPH Version: librbd1-10.2.5-4.el7 Open vSwitch Version: openvswitch-2.11.0-4.el7 Kernel Features: PTI: 1, IBRS: 0, RETP: 1, SSBD: 3 VNC Encryption: Disabled What else can I check? On Fedora I have virt-viewer-8.0-3.fc31.x86_64 Gianluca

Re: Damaged hard disk in volume replica gluster
by Strahil 25 Feb '20

25 Feb '20

As you are replacing an old brick, you have to recreate the old LV and mount it on the same location. Then you can use the gluster's "reset-brick" (i thing ovirt UI has that option too) and all data will be replicated there. You got also the "replace-brick" option if you decided to change the mount location. P.S.: with replica volumes your volume should be still working, in case it has stopped - you have to investigate before proceeding.

I'm a bit confused about adding a second network provider. If I understand it correctly, I have to add it on a host and then import it? Is that correct or am I miss reading it. Please enlighten me. Thanks.

HostedEngine Upgrade and Rollback
by jrbdeguzman05＠gmail.com 25 Feb '20

25 Feb '20

Hi Everyone, Our HostedEngine is previously running in version 4.3.7 then updated it to 4.3.8. Before the update, we did a full backup of the HE. After a successful update, we're testing to roll it back to the previous backup. The cluster setting has been rolled back but the Hosted version is still 4.3.8. Is there a best way to rollback a HostedEngine after a successful minor update? I've read somewhere that if an upgrade / update is unsuccessful, HostedEngine will be rolled back to the previous version automatically. Thanks in advance.

Is there a way to specify only certain disks to snapshot using the ansible playbooks? We have servers with hostname_disk0 and hostname_disk1. And i just want to create snapshots with the OS disk which is always hostname_disk0. Thanks in advance. Tom
