storage issue's with oVirt 3.5.1 + Nexenta NFS
by Maikel vd Mosselaar 22 Apr '15

22 Apr '15

Hi, We are running ovirt 3.5.1 with 3 nodes and seperate engine. All on CentOS 6.6: 3 x nodes 1 x engine 1 x storage nexenta with NFS For multiple weeks we are experiencing issues of our nodes that cannot access the storage at random moments (atleast thats what the nodes think). When the nodes are complaining about a unavailable storage then the load rises up to +200 on all three nodes, this causes that all running VMs are unaccessible. During this process oVirt event viewer shows some i/o storage error messages, when this happens random VMs get paused and will not be resumed anymore (this almost happens every time but not all the VMs get paused). During the event we tested the accessibility from the nodes to the storage and it looks like it is working normal, at least we can do a normal "ls" on the storage without any delay of showing the contents. We tried multiple things that we thought it causes this issue but nothing worked so far. * rebooting storage / nodes / engine. * disabling offsite rsync backups. * moved the biggest VMs with highest load to different platform outside of oVirt. * checked the wsize and rsize on the nfs mounts, storage and nodes are correct according to the "NFS troubleshooting page" on ovirt.org. The environment is running in production so we are not free to test everything. I can provide log files if needed. Kind Regards, Maikel

Move/Migrate Storage Domain to new devices
by Dael Maselli 22 Apr '15

22 Apr '15

Hi, I have a data storage domain that use one FC LUN. I need to move all data to a new storage server. I tried by move single disks to a new storage domain but some cannot be moved, I think because they are thin-cloned by template. When I worked with LVM I use to do a simple pvmove leaving the VG intact, is there something similar (online or in maintenance) in oVirt? Can I just do a pvmove from the SPM host o it's going to destroy everything? Thank you very much. Regards, Dael Maselli. -- ___________________________________________________________________ Dael Maselli --- INFN-LNF Computing Service -- +39.06.9403.2214 ___________________________________________________________________ * http://www.lnf.infn.it/~dmaselli/ * ___________________________________________________________________ Democracy is two wolves and a lamb voting on what to have for lunch ___________________________________________________________________

oVirt 3.6 new feature: NUMA aware KSM support
by David Maroshi 21 Apr '15

21 Apr '15

Greetings users and developers, Just put up a feature page for the "NUMA aware KSM support"; In summary, =========== The KSM service is optimizing shared memory pages across all NUMA nodes. The consequences is: a shared memory pages (controlled by KSM) to be read from many CPUs across NUMA nodes. Hence degrading (could totally eliminate) the NUMA performance gain. The optimal behavior is for KSM feature to optimize memory usage per NUMA nodes. This feature is implemented in KSM since RHEL 6.5. We want to introduce a new feature to oVirt that will allow host administrator to control NUMA aware KSM policy. You're welcome to review the feature page: http://www.ovirt.org/NumaAwareKsmSupport The feature page is responding to RFE https://bugzilla.redhat.com/show_bug.cgi?id=840114 Your comments appreciated. Thanks Joy and happiness Dudi -- Dudi Maroshi Software Engineer Red Hat Enterprise Virtualization project http://www.redhat.com/en/technologies/virtualization maroshi(a)redhat.com -------------------------------- I am perfectly imperfect.

"had" bei= ng the operative word here. Today I connected the second network interface and then went to the host an= d tried to bond this interface to the ovirt mgmt. network... this is where = the "had" part comes in ;-) Now I have no working interfaces at all, can't ping in or out and all inter= faces say they are down, en1, 2, ovrtmgmt and bond0 when I do an ip add (th= is is centos7) I have done this quite a few times on RHEV clusters and it always worked we= ll, very impressed with it. The differences are... RHEV cluster I was using trunked ports and VLANS RHEV I was using 6.4 or 6.5 RHEL I think that's it. I haven't really dug into the /etc/sysconfig/network-scripts to see what no= rmally goes into the config files to create a bonded interface - only to se= e how to configure my first interface with a vlan and then I let ovirtengin= e do the rest for me as it worked so wellI I guess I may have to rip it out and start over unless anyone has any tips = on fixing it. It's just PoC anyway, so learning.
