[ovirt-users] GlusterFS performance questions

I am currently in the process of researching converting an existing SMB infra to virtual. Ovirt/RHEV is a strong contender and checks off a lot of boxes on our list. GlusterFS is appealing but I am finding it very difficult to find any answers or stats/numbers regarding how well it can perform

That's the problem, at that time nobody has restarted the server. Is there any scenario when the hypervisor is restarted by engine? Cheers Erekle On 10/16/2017 04:45 PM, Piotr Kliczewski wrote: Erekle, For the time period you mentioned I do not see anything wrong on vdsm side except of a

Erekle, For the time period you mentioned I do not see anything wrong on vdsm side except of a restart at 2017-10-15 16:28:50,993+0200. It looks like manual restart. The engine log starts at 2017-10-16 03:49:04,092+02 so not able to say whether there was anything else except of heartbeat issue

Hi Piotr, Several times I've restarted vdsm daemon on certain nods, that could be the reason. The failure, I've mentioned, has happened yesterday from 15:00 to 17:00 Cheers Erekle On 10/16/2017 04:13 PM, Piotr Kliczewski wrote: Erekle, In the logs you provided I see: IOError: [Errno 5]

Re: [ovirt-users] MoM is failing!!!

Hi, Can you please tell us what is the issue that you are actually facing? :) it would be easier to debug an issue and not an error message that can be cause by several things. Also, can you provide the engine and the vdsm logs? thank you, Dafna On 10/16/2017 02:30 PM, Erekle Magradze wrote:

Re: [ovirt-users] MoM is failing!!!

Hi, how do you start MOM? MOM is supposed to talk to vdsm, we do not talk to libvirt directly. The line you posted comes from vdsm and vdsm is telling you it can't talk to MOM. Which MOM service is enabled? Because there are two momd and mom-vdsm, the second one is the one that should be

Hi, it is just a warning, there is nothing you have to solve unless it does not resolve itself within a minute or so. If it happens only once or twice after vdsm or mom restart then you are fine. Best regards -- Martin Sivak SLA / oVirt On Mon, Oct 16, 2017 at 2:44 PM, Erekle Magradze

[ovirt-users] Question about gluster network

Hi, My setup uses a separate physical network for gluster storage, this network is available on all hosts and defined as gluster network in the engine but the engine itself has no connection to that network. Does the engine need to have a connection to the gluster network? engine.log reports
