Hi, but i want the way from the ovirt portal...if possible ?? Yes, its possible. Also in my case if the mount point HV node goes down...all the VM's will pause...and once the node come up..i need to manually poweroff the VM's and manually start again... I failed to interpret 'mount

Hi Humble, Thanks for the update...the mount point is the ip address to mount the gluster volume,so if this server goes down...all the VM's will pause :- [image: Inline image 1] Some one from community suggest me to use the localhost instead of the ip address for HAbut i have doubt if i use

Hi Punit, If you are using gluster volume for virt store, it is always recommend to enable /considering virt store use case mentioned here : http://gluster.org/documentation/use_cases/Virt-store-usecase/ Regarding how to add bricks to the volume , you can refer #

[ovirt-users] GlusterFS Distributed Replicate HA with KeepAlived

Hi, I have 4 node GlusterFS Distributed Replicate volume...the same 4 host node i am using for compute purposenow i want to make it HAso if any host goes down .VM will not pause and it will migrate to another available node... 1. Can any one have any document or reference to do this

Re: [ovirt-users] Glusterfs HA with Ovirt

I was never able to achieve a stable system that could survive the loss of a single node with glusterfs. I attempted to use replica 2 across 3 nodes (which required 2 bricks per node as the number of bricks must be a multiple of the replica, and you have to order them so the brick pairs span

[ovirt-users] Glusterfs HA with Ovirt

Hi, I have some HA related concern about glusterfs with Ovirt...let say i have 4 storage node with gluster bricks as below :- 1. 10.10.10.1 to 10.10.10.4 with 2 bricks each and i have distributed replicated architecture... 2. Now attached this gluster storge to ovrit-engine with the following

Re: [ovirt-users] Glusterfs HA with Ovirt

You need to setup a virtual IP to use as the mount point, most people use keepalived to provide a virtual ip via vrrp for this. Setup something like 10.10.10.10 and use that for your mounts. Right now, if 10.10.10.2 goes away, all your gluster mounts go away and your VMs get paused because the

Hi, Thanks...can you suggest me any good how to/article for the glusterfs with ovirt... One strange thing is if i will try both (compute storage) on the same node...the below quote not happen - Right now, if 10.10.10.2 goes away, all your gluster mounts go away and your

Re: [ovirt-users] Glusterfs HA with Ovirt

Don't forget to take into consideration quroum, that's something people often forget The reason you're having the current happen, is gluster only uses the initial IP address to get the volume details. After that it'll connect directly to ONE of the servers, so with your 2 storage server case, 50%

Re: [ovirt-users] Glusterfs HA with Ovirt

Hi Andrew, Thanks for the updatethat means HA can not work without VIP in the gluster,so better to use the glusterfs with the VIP to take over the ip...in case of any storage node failure... On Fri, Jul 4, 2014 at 12:35 PM, Andrew Lau and...@andrewklau.com wrote: Don't forget to take into

Re: [ovirt-users] Glusterfs HA with Ovirt

Hi Andrew, Yes..both on the same node...but i have 4 nodes of this type in the same clusterSo it should work or not ?? 1. 4 physical nodes with 12 bricks each(distributed replicated)... 2. The same all 4 nodes use for the compute purpose also... Do i still require the VIP...or not ??

Re: [ovirt-users] glusterfs resume vm paused state

Hi Itamar, i assume this is around gluster deployment/split-brains/etc., since we try to resume and fail We are progressing on bz. Looks like quorum configuration playing a role here. I will follow up on the same bug report. --Humble On Mon, Jun 16, 2014 at 7:10 PM, Itamar Heim

Hi, that has been fixed since 3.3 with auto-resume paused vm's after EIO Thanks Itamar . I had a BZ open about this with some traction, but i forgot to keep up with the requests and it's fallen behind https://bugzilla.redhat.com/show_bug.cgi?id=1058300 Even manually, they won't resume.

[ovirt-users] glusterfs resume vm paused state

Hi, Has anyone had any luck with resuming a VM from a paused state on top of NFS share? Even when the VMs are marked as HA, if the gluster storage goes down for a few seconds the VMs go to a paused state and can never be resumed. They require a hard reset. I recall when using NFS to not have
