soft negative affinity
by Kapetanakis Giannis
Hi,
Can someone comment on this?
https://bugzilla.redhat.com/show_bug.cgi?id=1207255
I've defined a soft negative affinity group for two VMs.
To my understanding if the there are at least 2 nodes available in the
cluster
then the VMs SHOULD start on different nodes.
This does not happen. They start on the same node.
If I make it hard then it works.
However I don't want to make it hard since if there is only one node
available in the cluster then one vm will stay down.
regards,
Giannis

Options not being passed fence_ipmilan, Ovirt3.5 on Centos 7.1 hosts
by Mike Lindsay
Hi All,
I have a bit of an issue with a new install of Ovirt 3.5 (our 3.4 cluster
is working fine) in a 4 node cluster.
When I test fencing (or cause a kernal panic triggering a fence) the
fencing fails. On investigation it appears that the fencing options are not
being passed to the fencing script (fence_ipmilan in this case):
Fence options under GUI(as entered in the gui): lanplus, ipport=623,
power_wait=4, privlvl=operator

Is it possible to limit the number and speed of paralel STORAGE migrations?

Content-Type: text/plain; charset=utf-8; format=flowed

Ovirt uses dd and qemu-img for live migration. Is it possible to limit
the number of concurrent live storage moves or limit the bandwidth used?
I'd like to move about 30 disks to another storage during the night, but
each takes about 30 minutes each and if more than one runs, it chokes my
storage.

storage issue's with oVirt 3.5.1 + Nexenta NFS
by Maikel vd Mosselaar
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
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.
