Disk migration eats all CPU, vms running in SPM become unresponsive
by Federico Alberto Sayd 24 Jul '14

24 Jul '14

Hello: I am experiencing some troubles with ovirt nodes: When a node is selected as SPM and I move a disk between storage domains, it seems that migration process eats all CPU and some VMs (running on the SPM) hang, others lose network connectivity. The events tab at Ovirt Engine reports the CPU exceeding the defined threshold and then reports that VMs in such host (SPM) are not responding. How can I debug this? Why do the VMs become unresponsive or lost network connectivity when the host CPU goes too high? I have attached a screenshot of the ovirt-engine events, and the relevant engine.log My setup: oVirt Engine Version: 3.4.0-1.el6 (Centos 6.5) Nodes: Centos 6.5 vdsm-4.14.6-0.el6 libvirt-0.10.2-29.el6_5.9 KVM: 0.12.1.2 - 2.415.el6_5.10 (jenkins build) Regards Federico

------=_Part_27854792_967363234.1405525563715 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit Hi, We have a production environment with KVM+centos6 and we want to switch to ovirt. At this moment we have 12 VM on three independent server. This VMs uses the local disks of servers, we don't have a central storage. currently we have for ovirt - Two Dell R710 with 128 gigs of ram. - A third dell server for ovirt-engine. - four 1 gb/sec NICs/ server. - Smart GB switch we would like make an ovirt environment with - clusterized, redundant filesystem, data loss protection - If a host goes to down the VMs could made a restart on the remain host - LACP/bonding (mode 6) for fast I/O beetwen gluster hosts, we don't have 10Gbe nics - 8 TB of disk capacity for VMs we don't want: - using hw raid on servers, because we need free disk tray for more capacity My questions. - Which glusterfs method is the best for us for performance? - Can I make a real "performance" disk i/o by 4-4 NICs ? Or I need 10 Gbe nic for this? - How much disk need for good redundancy/performance? 4/server or 2/server ? - What will the weak point our project? Thanks in advance.

Can we debug some truths/myths/facts about hosted-engine and gluster?
by Andrew Lau 24 Jul '14

24 Jul '14

Hi all, As most of you have got hints from previous messages, hosted engine won't work on gluster . A quote from BZ1097639 "Using hosted engine with Gluster backed storage is currently something we really warn against. I think this bug should be closed or re-targeted at documentation, because there is nothing we can do here. Hosted engine assumes that all writes are atomic and (immediately) available for all hosts in the cluster. Gluster violates those assumptions. " Until the documentation gets updated, I hope this serves as a useful notice at least to save people some of the headaches I hit like hosted-engine starting up multiple VMs because of above issue. Now my question, does this theory prevent a scenario of perhaps something like a gluster replicated volume being mounted as a glusterfs filesystem and then re-exported as the native kernel NFS share for the hosted-engine to consume? It could then be possible to chuck ctdb in there to provide a last resort failover solution. I have tried myself and suggested it to two people who are running a similar setup. Now using the native kernel NFS server for hosted-engine and they haven't reported as many issues. Curious, could anyone validate my theory on this? Thanks, Andrew

Ovirt nodes lose up status
by Fabien CARRE 23 Jul '14

23 Jul '14

Hello, I am experiencing an issue with on my current ovirt DC. The setup is 2 machines running Ovit Nodes connected to a LaCie 12big Rack Fibre 8, the nodes are connected to both controllers..

I just tried that and Cluster Validation gives me this error for the intended shared disk (direct lun, attached to two VM's, shareable, privileged scsi): "Disk bus does not support clustering. The required inquiry data (SCSI page 83h VPD descriptor) was reported as not being supported." In the report, the VPD Page 83h identifier is listed as <Unknown>. This seems to be an issue outside of oVirt, stgt only supports this field since version 1.0.46: http://www.spinics.net/lists/linux-stgt/msg04349.html Since I'm running CentOS 6 on the machine that hosts the scsi targets which has 1.0.25, if RedHat hasn't backported that feature, it's not supported. -- Tiemen Ruiten Systems Engineer R&D Media

[QE][ACTION SUGGESTED] oVirt 3.4.4 development status
by Sandro Bonazzola 23 Jul '14

23 Jul '14

Hi, We've started developing oVirt 3.4.4 after 3.4.3 release. Suggested timeline[1] is: - General availability: 2014-09-16 - RC Build: 2014-09-09 A bug tracker [2] has been opened and shows no open blockers. There are still 12 bugs [3] targeted to 3.4.4. Excluding node and documentation bugs we still have 4 bugs [4] targeted to 3.4.4. Maintainers / Assignee: - Please add the bugs to the tracker if you think that 3.4.4 should not be released without them fixed. - Please update the target to 3.5.0 or later for bugs that won't be in 3.4.4: it will ease gathering the blocking bugs for next releases. - Please fill release notes, the page has been created here [5] Community: - If you're testing oVirt 3.4 nightly snapshot, please add yourself to the test page [6] [1] http://www.ovirt.org/OVirt_3.4.z_release-management#oVirt_3.4.4 [2] http://bugzilla.redhat.com/1118689 [3] http://red.ht/1qwhPXB [4] http://red.ht/1sQDLwg [5] http://www.ovirt.org/OVirt_3.4.4_Release_Notes [6] http://www.ovirt.org/Testing/oVirt_3.4.4_Testing -- Sandro Bonazzola Better technology.

request for version 3.5 can novnc be the default? i like native vnc and spice clients too, but for new users this would be much easier. esp for mac (and mobile device) users who cant get remoteviewer.app working. thanks!

Odd messages on new node/hosted engine
by Chris Adams 23 Jul '14

23 Jul '14

I built a new node+hosted engine setup, using up-to-date 6.5 and oVirt 3.4.3-RC. I see some odd messages, that I think are probably related: - In the hosted engine UI, I have an Alert that says "Failed to verify Power Management configuration for Host hosted_engine_1." - On the node, I get the following chunk repeated every 10 seconds in /var/log/messages: Jul 16 14:34:19 node0 kernel: device-mapper: table: 253:2: multipath: error getting device Jul 16 14:34:19 node0 kernel: device-mapper: ioctl: error adding target to table Jul 16 14:34:19 node0 kernel: device-mapper: table: 253:2: multipath: error getting device Jul 16 14:34:19 node0 kernel: device-mapper: ioctl: error adding target to table Jul 16 14:34:19 node0 multipathd: dm-2: remove map (uevent) Jul 16 14:34:19 node0 multipathd: dm-2: devmap not registered, can't remove Jul 16 14:34:19 node0 cpuspeed: Disabling performance cpu frequency scaling governor Jul 16 14:34:19 node0 multipathd: dm-2: remove map (uevent) Jul 16 14:34:19 node0 multipathd: dm-2: devmap not registered, can't remove Jul 16 14:34:19 node0 multipathd: dm-2: remove map (uevent) Jul 16 14:34:19 node0 multipathd: dm-2: devmap not registered, can't remove Jul 16 14:34:19 node0 multipathd: dm-2: remove map (uevent) Jul 16 14:34:19 node0 multipathd: dm-2: devmap not registered, can't remove Jul 16 14:34:20 node0 cpuspeed: Enabling performance cpu frequency scaling governor There is no dm-2; the system is installed on 2 SAS drives, mirrored using Linux md RAID1, using LVM (dm-0 is the root filesystem and dm-1 is swap).

status disks locked
by Andy Michielsen 23 Jul '14

23 Jul '14

Hello, I have a vm in my ovirt setup which has it's disks locked after I wanted to take a snapshot. I have a separate node and an engine and already rebooted them both but it still keeps on telling me it's disks are locked. Where does this info come from and what can I do to rectify the situation. Kind regards.

user permissions
by Jorick Astrego 23 Jul '14

23 Jul '14

Hi, In our 3.4.3 environment I started adding external users (it is connected to a freeipa server) and I'm having some problems setting the correct permissions. When I give all user roles to a user, I cannot create a vm and get an error "User is not authorized to perform this action". I tried setting it on the system level, DC level and cluster level. I needed to give this user an administrator role with only exactly the same vm and disk permissions (nothing extra) and things work ok, but he can now login to the admin portal. So I blocked it with a .htaccess which is not the prettiest solution. Am I doing things wrong? Also the user disappeared from the "System permissions" overview but can still login, which is a bit weird. Kind regards, Jorick Astrego Netbulae

Snapshots auto generated for live Storage
by André Freitas 23 Jul '14

23 Jul '14

Hi, after i had successfully migrated the disks to a different nfs datastore, i now have a vm with 3 snapshots: 1 current with the description "Active VM" and 2 more with the description "Auto-generated for Live Storage". For what i have been reading online, i can only delete snapshots with the vm offline. is this true? Second, should i commit the live storage snapshots before i delete them or its safe to delete them without commit?

Backup solutions for Ovirt
by saurabh 22 Jul '14

22 Jul '14

Hi All, I am using Ovirt for my QA environment almost 15 virtual servers, and it is working as expected. The only thing I am worried about is the backup solutions in case of failure or system crash. I tried looking into the LVM structure that is created by Ovirt but it seems a bit complex. Please let me know the proper solution (if there is any) for backing up my environment in case of failure.

Misaligned Disk after resize
by Neil 22 Jul '14

22 Jul '14

Hi guys, We re-sized (expanded) a Server 2003 VM a few weeks back and since then the CPU load seems to be rather excessive. Also in the oVirt GUI it reports the disk is misaligned, I've done a bit of reading and it sounds like the only way to correct the alignment again is to re-install, is this the only option? Thank you. Regards. Neil Wilson.
