LVM2 Thinprovisioned
by Fernando Frediani 14 Aug '16

14 Aug '16

Hello all. When you use oVirt with a Block Storage the only option available to store de VMs is LVM. Does LVM in oVirt use Thinprovisoned (supported in LVM2) instead of having to use the SAN Thinprovisioned features ? Fernando

General system updates policy
by David Gossage 14 Aug '16

14 Aug '16

Is it considered safe from an ovirt stability standpoint to apply yum updates to the hosts and engine as centos/redhat release them? For example the recent https://rhn.redhat.com/errata/RHSA-2016-1606.html update for qemu. If I run yum update and update that is their any worry for me that it has not been tested with oVirt and so versions will break something. Same with kernels, libraries etc.. *David Gossage* *Carousel Checks Inc. | System Administrator* *Office* 708.613.2284

ovirt 3.6.6 and gluster 3.7.13
by David Gossage 13 Aug '16

13 Aug '16

Anyone running one of recent 3.6.x lines and gluster using 3.7.13? I am looking to upgrade gluster from 3.7.11->3.7.13 for some bug fixes, but have been told by users on gluster mail list due to some gluster changes I'd need to change the disk parameters to use writeback cache. Something to do with aio support being removed. I believe this could be done with custom parameters? But I believe strage tests are done using dd and would they fail with current settings then? Last upgrade to 3.7.13 I had to rollback to 3.7.11 due to stability isues where gluster storage would go into down state and always show N/A as space available/used. Even if hosts saw storage still and VM's were running on it on all 3 hosts. Saw a lot of messages like these that went away once gluster rollback finished [2016-07-09 15:27:46.935694] I [fuse-bridge.c:4083:fuse_init] 0-glusterfs-fuse: FUSE inited with protocol versions: glusterfs 7.22 kernel 7.22 [2016-07-09 15:27:49.555466] W [MSGID: 114031] [client-rpc-fops.c:3050:client3_3_readv_cbk] 0-GLUSTER1-client-1: remote operation failed [Operation not permitted] [2016-07-09 15:27:49.556574] W [MSGID: 114031] [client-rpc-fops.c:3050:client3_3_readv_cbk] 0-GLUSTER1-client-0: remote operation failed [Operation not permitted] [2016-07-09 15:27:49.556659] W [fuse-bridge.c:2227:fuse_readv_cbk] 0-glusterfs-fuse: 80: READ => -1 gfid=deb61291-5176-4b81-8315-3f1cf8e3534d fd=0x7f5224002f68 (Operation not permitted) [2016-07-09 15:27:59.612477] W [MSGID: 114031] [client-rpc-fops.c:3050:client3_3_readv_cbk] 0-GLUSTER1-client-1: remote operation failed [Operation not permitted] [2016-07-09 15:27:59.613700] W [MSGID: 114031] [client-rpc-fops.c:3050:client3_3_readv_cbk] 0-GLUSTER1-client-0: remote operation failed [Operation not permitted] [2016-07-09 15:27:59.613781] W [fuse-bridge.c:2227:fuse_readv_cbk] 0-glusterfs-fuse: 168: READ => -1 gfid=deb61291-5176-4b81-8315-3f1cf8e3534d fd=0x7f5224002f68 (Operation not permitted) *David Gossage* *Carousel Checks Inc. | System Administrator* *Office* 708.613.2284

IE: 4.0.2 I did a repo list and found - centos-ovirt40-candidate Than found that 4.0.2 its also coming down from the ovirt-4.0 repo... ovirt-engine-sdk-python noarch 3.6.8.0-1.el7 centos-ovirt40-candidate 480 k ovirt-release40 noarch 4.0.2-2 ovirt-4.0 8.3 k ovirt-vmconsole noarch 1.0.4-1.el7 centos-ovirt40-candidate 29 k ovirt-vmconsole-proxy noarch 1.0.4-1.el7 centos-ovirt40-candidate 17 k python-ovirt-engine-sdk4 x86_64 4.0.0-0.5.a5.el7 centos-ovirt40-candidate 308 k Is this safe to upgrade?

Failed to activate Storage Domain vms (Data Center Default)
by Gonzalo Faramiñan 12 Aug '16

12 Aug '16

Hello everyone, I'm brand new to oVirt, but anyway I'm trying to solve a problem because of staff changes. Any help is really appreciated. Context: - oVirt Engine Version: 3.1.0-3.19.el6 running on Centos 6.7 - two nodes running Centos 6.7 connected with Gluster 3.3.1.15.el6, replicate configured - six VMs with high-availability on six separated virtual disk created into de Default volume. The Data Center was working fine for a few years and after a maintenance (step-by-step well done) reboot, the Default volume lost GBs of data. Just 23MB of replicated data remained :_( Now the Master Storage Domain seems to be broken and we cannot get it up and running in any way. Whatever we try, we end up facing this message: "No valid Data Storage Domains are available in Data Center Default (please check your storage infrastructure)." Over this list we saw same log messages, but couldn't solve the problem. I include what I think are the main error messages Thanks in advance! Webgui: 2016-Aug-12, 14:37:11 Host nodo2 cannot access one of the Storage Domains attached to it, or the Data Center object.

oVirt updates available on host due to libvirt missing
by Gianluca Cecchi 12 Aug '16

12 Aug '16

Hello, My self hosted engine environment was born in 3.6.0 in November with CentOS 7 on host and CentOS 7 appliance. I managed several updates applying 3.6.2, then 3.6.5, then 4.0. Now I'm at 4.0.2 final and in web admin gui I see a message regarding updates available on host (hosted_engine_1) that doesn't go away. The host usually was updated through "yum update" and not from the gui during updates described above. In events pane it seems the problem is related with libvirt package Host hosted_engine_1 has available updates: libvirt. Actually at this moment the libvirt package (that seems actually a sort of meta-package) is not installed and I think has been never here. Situation is: [root@ractor log]# rpm -qa|grep libvirt libvirt-daemon-driver-network-1.2.17-13.el7_2.5.x86_64 libvirt-daemon-driver-interface-1.2.17-13.el7_2.5.x86_64 libvirt-daemon-kvm-1.2.17-13.el7_2.5.x86_64 libvirt-client-1.2.17-13.el7_2.5.x86_64 libvirt-daemon-1.2.17-13.el7_2.5.x86_64 libvirt-lock-sanlock-1.2.17-13.el7_2.5.x86_64 libvirt-daemon-driver-storage-1.2.17-13.el7_2.5.x86_64 libvirt-daemon-driver-qemu-1.2.17-13.el7_2.5.x86_64 libvirt-daemon-driver-nodedev-1.2.17-13.el7_2.5.x86_64 libvirt-python-1.2.17-2.el7.x86_64 libvirt-daemon-config-nwfilter-1.2.17-13.el7_2.5.x86_64 libvirt-daemon-driver-nwfilter-1.2.17-13.el7_2.5.x86_64 libvirt-daemon-driver-secret-1.2.17-13.el7_2.5.x86_64 [root@ractor log]# If I run "yum install libvirt" I'm proposed: Dependencies Resolved ==================================================================================================== Package Arch Version Repository Size ==================================================================================================== Installing: libvirt x86_64 1.2.17-13.el7_2.5 updates 119 k Installing for dependencies: libvirt-daemon-config-network x86_64 1.2.17-13.el7_2.5 updates 120 k libvirt-daemon-driver-lxc x86_64 1.2.17-13.el7_2.5 updates 747 k Transaction Summary ==================================================================================================== Install 1 Package (+2 Dependent packages) How to proceed?
