[Users] FW: ovirt 3.2.1 custom bonding options

[Sven Knohsalla]

Hi,

for all oVirt users who wants to run their nodes in balance-rr mode:
Go to "Network Interfaces"
--> "Setup Host Networks"

Edit the bond interface you want to change
--> "Bonding mode"--> "Custom:"
--> "Custom mode" --> mode=0 miimon=100 (depends on your scenario)

Make sure you did activate the checkbox "Save network configuration",
press OK.

Verify on node-console via cat /proc/net/bonding/bond[n]:

Ethernet Channel Bonding Driver: v3.7.1 (April 27, 2011)

Bonding Mode: load balancing (round-robin)
MII Status: up
MII Polling Interval (ms): 100
Up Delay (ms): 0
Down Delay (ms): 0

Slave Interface: em1
MII Status: up
Speed: 1000 Mbps
Duplex: full
Link Failure Count: 0
Permanent HW addr: d4:ae:52:e8:26:a1

Very useful to power up network throughput for oVirt mgmt. network with single 
1GBit connections only.

Cheers,
Sven.

Betreff: ovirt 3.2.1 custom bonding options

Hi,

just have a tiny question, regarding bonding & custom mode:
If I want to run a bond in mode 2 with miimon=100,
how needs the custom text field look like:
BONDING_OPTS="miimon=100 mode=0" ?

(would be equivalent to ifcfg config file)


Thanks in advance!

Cheers,
Sven.

Re: [Users] ids sanlock error

[Tony Feldmann]

I was messing around with some things and force removed my DC.  My cluster
is still there with the 2 gluster volumes, however I cannot move that
cluster into a new dc, I just get the following error in engine.log:

2013-06-25 20:26:15,218 ERROR

I would really like to get this back into a dc without destroying my
gluster volumes and losing my data.  Can anyone please point me in the
right direction?

Re: [Users] Fedora upgrading from 3.1 to 3.2

[Matthew Curry]

Has anyone tried 3.1 to 3.2 in CentOS? or even 3.1 to 3.3rc/beta/etc?? I 
am going to be forced down that path soon; so I am wondering what kind 
of hurt I am in for...

Lol...

Yes, I had much better success following that article, and managed to 
upgrade fedora to 18, had to tune my kernel parameters a little for 
the postgres upgrade to work, but then engine-upgrade fails just as 
it did the last time we tried. The log is attached. Hoping to hear 
back from you soon with ideas on what to try next.

 But now the error seems different from the original one in March 
(if I remember correctly the original post).


 
They are quite the same:

Could it be somehow related with this rhev one bug:

 https://bugzilla.redhat.com/show_bug.cgi?id=923614



 and that changing permissions for the impacted objects in db before 
running upgrade could help?


 
Very interesting, thanks for the hint! That is definitely worth 
trying out. Will try that first thing tomorrow:)


Hi Karli

If it helps, let me know - I will add a troubleshooting section to the 
wiki.









 BTW: is your environment directly created in 3.1 or did it come 
from a further upgrade? 


 
Started with a minimal Fedora 17 install, added the oVirt-3.1 repo, 
ran yum upgrade -y first, then yum install -y ovirt-engine and lastly 
engine-setup. Nothing more. So it´s just an empty engine that I´m 
trying to upgrade at this point. When that works, I´ll add hosts, 
VMs, Templates, etc.

[Users] VM Pausing with Storage IO errors

[Jason Lawer]

Hi,

I have a ovirt 3.2.1 system that has a single VM which pauses soon after 
launch with the message "VM has been paused due to storage IO error". 
When it first occured it mentioned an issue with no storage. This is 
weird as it says I have over half of my 4TB iscsi pool free. I have 
checked the SAN, hosts and engine logs. I haven't been able to find 
anything that indicates the cause.


Is anyone able to at least point me in the direction I should look further?

Details :

3x Dell R720 VM Nodes (Dual Proc Sandy bridge Xeon, 96gb ram, boot from 
SAN)


Dell MD 3220i iSCSI storage array

Hosts are runing
  CentOS 6.4
   VDSM : vdsm-4.10.3-0.36.23.el6
   libvirt : libvirt-0.10.2-18.el6_4.8
   kernel : 2.6.32 - 358.11.1.el6.x86_64
   kvm : 0.12.1.2 - 2.355.el6.5

But now the error seems different from the original one in March (if I
remember correctly the original post).
Could it be somehow related with this rhev one bug:
https://bugzilla.redhat.com/show_bug.cgi?id=923614
and that changing permissions for the impacted objects in db before running
upgrade could help?

BTW: is your environment directly created in 3.1 or did it come from a
further upgrade?

HIH,

[Users] ids sanlock error

[Tony Feldmann]

I have a 2 node cluster with engine running on one of the nodes.  It has 2
gluster volumes that replicate between the hosts as its shared storage.
Last night one of my systems crashed.  It looks like all of my data is
present, however the ids file seems to be corrupt on my master domain.  I
tried to do a hexdump -c on the ids file, but it just gave an input/output
error.  Sanlock.log shows error -5.  Is there a way to rebuild the ids
file, or can I tell ovirt to use the other domain as the master so I can
get back up and running?

Hi Karli



Well, it wasn´t with me for long, I have hit BZ 911939 and 901786, 
where fedup fails to find my LVM volumes. In the dracut shell (to 
where it gets dropped), I have good output from blkid and lvm 
pvs|vgs|lvs but no nodes created in /dev/mapper and so the system 
cannot boot and upgrade fails. Do you have any suggestions there that 
might help? In the mean time, I´ll try upgrading using 
http://fedoraproject.org/wiki/Upgrading_Fedora_using_yum instead, see 
if that gives better success.




Sorry to hear that. Different people have experienced multiple 
problems upgrading lvm-based F17 systems to F18. I don't think that 
there's a magic solution that would just work, each case is usually 
solved on its own.


Let us know how you progress with upgrading with yum.

Alex.


i used same article [1] and had a successful go with it - good luck...

Hi,

adding michael for the rest of the question, but please note to check for SPM

also, may i ask what you are trying to accomplish (it sounds like a power

I was exploring the python sdk to figure out Host-VMs mapping i.e What

Looks like the only way to find this, is to query each VM in /api/vms
list to get the host on which it is running.

Is this the right way ? Is there no direct query or REST API to list
the VMs running on a given host at that instant.


you can run query="host = X" for that.



I was looking to get the data center hierarchy structure.
Number_of_datacenters

V
clusters in each data center
|
V
Hosts in each cluster
|
V
   VMs on each host.

This kind of mapping as seen on the GUI. Is there any way to obtain
the same from the ovirt-python-sdk ?


you can combine query to fetch vms by dc+cluster+host,

query = "datacenter = x and cluster = y and host = z"


this is redundnat, since host is in one cluster which is in one 
datacenter, so just querying on host would give the same result.




also you can fetch hosts from the given cluster

cluster=x

same for cluster

"Datacenter.name = x"



With this information, this would help me write scripts to turn-off my
hosts if idle automatically and power them on as required.

Deepthi

Yes, I was looking to tweak the power saving policy to switch off
hosts that have no VMs running on them. Looks like doing it within the

you should soon be able to write it via python sdk/scripts integrated
