Re: [ovirt-users] [Gluster-users] GlusterFS performance with only one drive per host?

The bottleneck is definitely not the disk speed with glusterFS, no point of using SSD for bricks what so ever -v On Thu, Mar 22, 2018 at 6:01 AM, Sahina Bose wrote: > > > On Mon, Mar 19, 2018 at 5:57 PM, Jayme wrote: >> >> I'm spec'ing a new oVirt build using three Dell R720's w/ 256GB. I'm >>

Re: [ovirt-users] [Gluster-users] GlusterFS performance with only one drive per host?

My take is that unless you have loads of data and are trying to optimize for cost/TB, HDDs are probably not the right choice. This is particularly true for random I/O workloads for which HDDs are really quite bad. I'd recommend a recent gluster release, and some tuning because the default settings

Re: [ovirt-users] [Gluster-users] GlusterFS performance with only one drive per host?

I would go with at least 4 HDDs per host in RAID 10. Then focus on network performance where bottleneck usualy is for gluster. On Sat, Mar 24, 2018, 00:44 Jayme wrote: > Do you feel that SSDs are worth the extra cost or am I better off using > regular HDDs? I'm looking for the best performanc

Do you feel that SSDs are worth the extra cost or am I better off using regular HDDs? I'm looking for the best performance I can get with glusterFS On Fri, Mar 23, 2018 at 12:03 AM, Manoj Pillai wrote: > > > On Thu, Mar 22, 2018 at 3:31 PM, Sahina Bose wrote: > >> >> >> On Mon, Mar 19, 2018 at

What version of ovirt and gluster? Sounds like something I just saw with gluster 3.12.x, are you using libgfapi or just fuse mounts? > From: Sahina Bose > Subject: Re: [ovirt-users] gluster self-heal takes cluster offline > Date: March 23, 2018 at 1:26:01 AM CDT > To: Jim

Thank you for the replies. While waiting, I found one more google responce that said to run engine-setup. I did that, and it fixed the issue. the VM is now running again. As to checking the logs, I'm not sure which ones to check...there are so many in so many different places. I was not able t

Re: [ovirt-users] Gluster: VM disk stuck in transfer; georep gone wonky

I read somewhere about clearing out wrong stuff from the UI by manually editing the database, maybe you can try searching for something like that. With regards to the VM, I'd probably just delete it, edit the DB and remove all sorts of references to it and then recover it from backup. Is there

Unfortunately, I came under heavy pressure to get this vm back up. So, i did more googling and attempted to recover myself. I've gotten closer, but still not quite. I found this post: http://lists.ovirt.org/pipermail/users/2015-November/035686.html Which gave me the unlock tool, which was succ
