Re: [ovirt-users] Ovirt 3.5 problem adding GlusterFS servers

[Sahina Bose]

Is the ovirt repo configured as well as on the 2 gluster servers?
ovirt-engine requires vdsm-gluster to communicate to gluster. Please 
check if vdsm-gluster can be installed on these servers

GlusterFS is running on the two VMs and I did configure a volume and 
did change the uid/gid to 36

so what's the problem?

Re: [ovirt-users] [Gluster-users] GlusterFS for production use with Ovirt

[Punit Dambiwal]

Hi Paul,

Thanks for the updates...

A few things to clarify
1) are all 4 for Gluster or are they the whole cluster.keep in mind that
Ovirt expects that you are running Gluster on different nodes than your
VM's. while I do not completely agree with that idea that is how it is now.
Comment :- All 4 servers are the part of the one gluster volume...

2) RAID hardware is not necessarily a bad thing, in fact the cache may help
significantly. that said  it is not required.things to keep in mind if you
are using RAID hardware for performance..
2.a) RAID 0 will give you the best speed if you are using 3 nodes for quorum.
keep in mind this will require more work in the case of a drive failure to
remake the brick.
2.b) if you are only doing a mirror across 2 bricks RAID 0 may be acceptable
but consider using 1+0 or RAID 5 the performance on the two may vary
depending on the RAID controller but 1+0 is generally faster.
2.c) always optimize for the stripe which in theory should be automatic if
the RAID controller reports the required information to do it, but in
practice most do not so you should do it manually and Red Hat's support
site just added a nice tool to do it for you.
Comment :- What about if i will split my 24 SSD in to two virtual drive
with RAID 6...actually i want to leverage the performance of the
SSD..without wastage too much of the disk capacity and redundancy...

Thanks,
Punit

[ovirt-users] GlusterFS for production use with Ovirt

[Punit Dambiwal]

Hi,

I want to use Glusterfs with Ovirt 3.5...please help me to make the
architecture stable for the production use :-

I have 4 servers...every server can host 24 SSD disk(As bricks)..i want to
deploy distributed replicated storage with replica =2i don't want to
use the Hardware RAID...as i think it will badly impact the performance...

1. Glusterfs 3.5 or 3.6 ?? (which one will be stable for the production
use).
2. Do i use the Hardware RAID or Not ??
3. IF HW RAID then which RAID level and does it impact the performance...
4. I want to make it rock solid...so it can use for production purpose...
5. How much RAM should be sufficient on each server...on the each server i
have two E5 CPU's...
6. For Network Connectivity i have 2*10G NIC with bonding on each server...

For those following this I've added a comment on the bz [1], although in

There have been multiple issue regarding net config upgrade. We might
have nailed an important one regarding ovirt-node.

However, I'd like to learn more about your report regarding new systems.
Your report sounds similar to

Bug 1203422 - vdsm should restore networks much earlier, to let
net-dependent services start

Besides Vdsm slowliness to start the network, what are the reasons for
your not wanting ovirt to touch your ifcfg? BTW, even today ovirt
overwrites ifcfg files, but only on network def time, to on every boot.

Yes, because vdsm/libvirt can't detect that the vm rebootet
and the vm starts with the old xml file.

I filed an RFE for this ages ago, let me look..here:
https://bugzilla.redhat.com/show_bug.cgi?id=1054070

But it might not match 100% your use case, so maybe
another RFE will push this further?

So I deleted 1.1.2, which should make these errors disappear. Let me know.

[ovirt-users] reboot doesn't allow modification to take effect.

[Nathanaël Blanchet]

Hi all,

I observed many times that modifying a vm when running needs a reboot to 
take effect (for instance for a RAM update), but rebooting it isn't 
enough. I have to halt the vm, and even somtimes power it off for having 
the expected changes.

Is it an expected behaviour?

[ovirt-users] Ovirt 3.5 problem adding GlusterFS servers

Hi,

Hello Dan,

Initially, I wanted to reduce the time of import process from the export
domain to my FC storage domain. In this context, I'm not limited by the SAN
(8Gbits) or the disk I/O (raid 5), but by the gigabit NIC.
My initial network configuration was to aggregate 2 nic (1 and 3) to a mode
4 bond0 and making vlan over it. So mode 4 is the best mode for this because
each vms ha its own MAC adress, so the 2gigabits BW are used as expected.
But the problematic of importing vms (the same as migrating them) is not the
same, because the flow is unique, so the bandwith is never useful.
What I decided to do, is to create a second non-LACP bridge bond1
aggragating nic2 and nic4 which is dedicated to the ovirtmgmt bridgeless
network.
Because this one is bridgeless, I add in the custom field the "mode=4
miion=100) options to have the round robin mode.
It seems to be ok after testing... please, tell me if I do something wrong.

it seems that you have a typo somewhere: "non-LACP bridge bond1...
dedicated to the ovirtmgmt bridgeless network". I suppose bond1 is a
bond with no bridge involved. If this is the case, I believe that you're
fine.

Re: [ovirt-users] Storage domain issue

[Nathanaël Blanchet]

Thnak you for reporting this issue because, I met exactly the same : FC 
storage domain and sometimes, many of my hosts (15 ) become sometimes 
unavailable without any apparent action on them.
The issue message is : storage domain is unvailable. So it is a desaster 
when power management is activated because hosts reboot at the same time 
and all VMs go down without migrating.
It happened to me two times, and the second time it was less a pity 
because I desactivated the power management.
It may be a serious issue because host stay reacheable and lun is still 
okay when doing a lvs command.
The workaround in this case is to restart the engine (restarting vdsm 
gives nothing) and then, all the hosts come up.


 * el6 engine on a separate KVM
 * implied el7 and el6 hosts
 * ovirt 3.5.1 and vdsm 4.16.10-8
 * 2 FC datacenter on two remote sites with the same engine and both
   are impacted

it seems that you have a typo somewhere: "non-LACP bridge bond1...
dedicated to the ovirtmgmt bridgeless network". I suppose bond1 is a
bond with no bridge involved. If this is the case, I believe that you're
fine.

[ovirt-users] Storage domain issue

[Jonas Israelsson]

Greetings.

Running oVirt 3.5 with a mix of NFS and FC Storage.

Engine running on a seperate KVM VM and Node installed with a pre 3.5 
ovirt-node "ovirt-node-iso-3.5.0.ovirt35.20140912.el6 (Edited)"


I had some problems with my FC-Storage where the LUNS for a while became 
unavailable to my Ovirt-host. Everything is now up and running and those 
luns again are accessible by the host. The NFS domains goes back online 
but the FC does not.

Re: [ovirt-users] 答复: bonding 802.3ad mode

[Nathanaël Blanchet]

Hello Dan,

Initially, I wanted to reduce the time of import process from the export 
domain to my FC storage domain. In this context, I'm not limited by the 
SAN (8Gbits) or the disk I/O (raid 5), but by the gigabit NIC.
My initial network configuration was to aggregate 2 nic (1 and 3) to a 
mode 4 bond0 and making vlan over it. So mode 4 is the best mode for 
this because each vms ha its own MAC adress, so the 2gigabits BW are 
used as expected.
But the problematic of importing vms (the same as migrating them) is not 
the same, because the flow is unique, so the bandwith is never useful.
What I decided to do, is to create a second non-LACP bridge bond1 
aggragating nic2 and nic4 which is dedicated to the ovirtmgmt bridgeless 
network.
Because this one is bridgeless, I add in the custom field the "mode=4 
miion=100) options to have the round robin mode.

It seems to be ok after testing... please, tell me if I do something wrong.

https://bugzilla.redhat.com/show_bug.cgi?id=1094842#c0
"""
Do not use tlb or alb in bridge, never! It does not work, that's it. The
reason is it mangles source macs in xmit frames and arps. When it is

all enterprise switches support that. Generally, for 99% of use cases,
you *should* use mode 4. There is no reason to use other modes.
"""


But for my own, I have several single kvm hosts that support bridge over
bonding in mode 0 and vms run fine on it...
So, someone can share his experience about this kind of detail?

ps: ovirt has a field for configuring custom mode whereas mode 0 is not
listed in the predifined list, I didn't make any test, but it seem to be at
least possible.

The bug referred above intends to make it a bit harder to make this
mistake. But in the good-old Un*x way, oVirt allows you to tweak things
that you actually should not, for fun or research.

[ovirt-users] suggestions of improvement

[Nathanaël Blanchet]

Hi all,

Two suggestions:

 * We use AD for authenticating users into the webadmin portal. But the
   preferences are common to everyone, especially bookmarks. Is it
   possible to add this kind of feature so as everyone to have a
   personnal session with his own preferences?
 * Some colleagues logon with the french translation of the webadmn,
   and they all do the same error when booting a vm : "run" and "run
   once" are translated in French to the same word "exécuter". So
   everybody "runs once" instead of a final run instance. I guess this
   needs to be opened in a BZ ticket.

[ovirt-users] issue to access to F5 menu with the console

[Nathanaël Blanchet]

Hi all,
I had trouble on a centos vm this morning, and as I used to do, I tried 
to enter into the interactive boot menu at the begining of the sequence 
boot so as to deactivate a service. But F5 just balances between the 
text console and the centos progression bar, and I've not been able yet 
to access to this menu. I've tried with SPICE and VNC console, but the 
issue is the same.

How can I do this like on any centos system?

Re: [ovirt-users] Ovirt GusterFS assistance

What is the type of volume that you've created? Is it a replicate volume?

# gluster volume info - should give you this information

If you're replicating the volume across 3 nodes, even when one of the 
server goes down, your storage domain should still be UP.


thanks

I am running 3 HP micro servers and 2 HP DL360 G5
The 3 micro servers are my glusterfs storage and have been provisioned 
for virt storage.

The 2 DL360 are my processing machines.

Now my 3 gluster hosts are in one cluster, the volume is in up status 
and has been provisioned for Virt Storage. But the problem is that my 
mount point is directed to one server, so when that server goes down, 
the volume storage domain goes down. I am not sure whether there is a 
way of mounting it by a "volume identity", so when a server goes down 
the storage domain stays up.


With my 2 processing hosts, I have them in one cluster, but I have not 
gotten any where with this, as I want the Virtual machines to use the 
gluster volume as storage but use the processing hosts hardware for 
processing power.


I would appreciate any assistance.

I can quote Jiri Pirko
https://bugzilla.redhat.com/show_bug.cgi?id=1094842#c0
"""
Do not use tlb or alb in bridge, never! It does not work, that's it. The
reason is it mangles source macs in xmit frames and arps. When it is
possible, just use mode 4 (lacp). That should be always possible because
all enterprise switches support that. Generally, for 99% of use cases,
you *should* use mode 4. There is no reason to use other modes.

The bug referred above intends to make it a bit harder to make this
mistake. But in the good-old Un*x way, oVirt allows you to tweak things
that you actually should not, for fun or research.

[ovirt-users] Ovirt GusterFS assistance

Hi I am trying to setup an Ovirt, Glusterfs, VM servers. I have followed
examples on setting up Ovirt and they have helped me so far, but not the

[ovirt-users] Snapshot issue

[Koen Vanoppen]

Dear all,

I have the following problem:

Cannot run VM. The VM is performing an operation on a Snapshot. Please wait
for the operation to finish, and try again.

It is like this since Friday... How can I resolve this? I really need this
vm to be up again...

Kind regards,

Koen
