Have you tried with: performance.strict-o-direct : off performance.strict-write-ordering : off They can be changed dynamically.

[ovirt-users] Very poor GlusterFS performance
Couple of things: 1. Like Darrell suggested, you should enable stat-prefetch and increase client and server event threads to 4. # gluster volume set <VOL> performance.stat-prefetch on # gluster volume set <VOL> client.event-threads 4 # gluster volume set <VOL> server.event-threads 4 2. Also glusterfs-3.10.1 and above has a shard performance bug fix -

[ovirt-users] Very poor GlusterFS performance
Dear Krutika, Sorry for asking so naively but can you tell me on what factor do you base that the client and server event-threads parameters for a volume should be set to 4? Is this metric for example based on the number of cores a GlusterFS server has? I am asking because I saw my GlusterFS volumes are set to 2 and would like to set these parameters to something meaningful for performance

[ovirt-users] Re: Gluster problems, cluster performance issues
Hi all again: I'm now subscribed to gluster-users as well, so I should get any replies from that side too. At this point, I am seeing acceptable (although slower than I expect) performance much of the time, with periodic massive spikes in latency (occasionally so bad as to cause ovirt to detect a engine bad health status). Often, if I check the logs just then, I'll see those call traces

[ovirt-users] Re: Gluster problems, cluster performance issues
I've been back at it, and still am unable to get more than one of my physical nodes to come online in ovirt, nor am I able to get more than the two gluster volumes (storage domains) to show online within ovirt. In Storage -> Volumes, they all show offline (many with one brick down, which is correct: I have one server off) However, in Storage -> domains, they all show down (although

[ovirt-users] Re: Gluster problems, cluster performance issues
The profile seems to suggest very high latencies on the brick at ovirt1.nwfiber.com:/gluster/brick1/engine ovirt2.* shows decent numbers. Is everything OK with the brick on ovirt1? Are the bricks of engine volume on both these servers identical in terms of their config? -Krutika On Wed, May 30, 2018 at 3:07 PM, Jim Kusznir <jim at palousetech.com> wrote: > Hi: > > Thank you. I

[Adding gluster-users back] Nothing amiss with volume info and status. Can you check the agent.log and broker.log - will be under /var/log/ovirt-hosted-engine-ha/ Also the gluster client logs - under /var/log/glusterfs/rhev-data-center-mnt-glusterSD<volume>.log On Wed, May 30, 2018 at 12:08 PM, Jim Kusznir <jim at palousetech.com> wrote: > I believe the gluster data store for

Gluster volume not mounted
The mount log file of the volume would help in debugging the actual cause.

Gluster volume not mounted
Good morning Gluster users, I'm very new to the Gluster file system. My apologies if this is not the correct way to seek assistance. However, I would appreciate some insight into understanding the issue I have. I have three nodes running two volumes, engine and data. The third node is the arbiter on both volumes. Both volumes were operation fine but one of the volumes, data, no longer

Adding Ravi to look into the heal issue. As for the fsync hang and subsequent IO errors, it seems a lot like https://bugzilla.redhat.com/show_bug.cgi?id=1497156 and Paolo Bonzini from qemu had pointed out that this would be fixed by the following commit: commit e72c9a2a67a6400c8ef3d01d4c461dbbbfa0e1f0 Author: Paolo Bonzini <pbonzini at redhat.com> Date: Wed Jun 21 16:35:46 2017

Hi Mahdi, Did you get a chance to verify this fix again? If this fix works for you, is it OK if we move this bug to CLOSED state and revert the rebalance-cli warning patch? -Krutika On Mon, May 29, 2017 at 6:51 PM, Mahdi Adnan <mahdi.adnan at outlook.com> wrote: > Hello, > > > Yes, i forgot to upgrade the client as well. > > I did the upgrade and created a new volume,

[ovirt-users] slow performance with export storage on glusterfs
What about mounting over nfs instead of the fuse client. Or maybe libgfapi. Is that available for export domains On Fri, Nov 24, 2017 at 3:48 AM Ji??
