Re: [Gluster-users] Slow performance of gluster volume

I'm assuming you are using this volume to store vm images, because I see shard in the options list. Speaking from shard translator's POV, one thing you can do to improve performance is to use preallocated images. This will at least eliminate the need for shard to perform multiple steps as part of

Re: [Gluster-users] Poor performance with shard

Hi, Speaking from shard translator's POV, one thing you can do to improve performance is to use preallocated images. This will at least eliminate the need for shard to perform multiple steps as part of the writes - such as creating the shard and then writing to it and then updating the aggregated

hi all this: $ vol heal $_vol info outputs ok and exit code is 0 But if I want to see statistics: $ gluster vol heal $_vol statistics Gathering crawl statistics on volume GROUP-WORK has been unsuccessful on bricks that are down. Please check if all brick processes are running. I suspect -

[Gluster-users] Poor performance with shard

Hey everyone! I have deployed gluster on 3 nodes with 4 SSDs each and 10Gb Ethernet connection. The storage is configured with 3 gluster volumes, every volume has 12 bricks (4 bricks on every server, 1 per ssd in the server). With the 'features.shard' off option my writing speed (using the 'dd'

Re: [Gluster-users] Glusterd proccess hangs on reboot

I have been using a 60 server 1560 brick 3.7.11 cluster without problems for 1 years. I did not see this problem with it. Note that this problem does not happen when I install packages & start glusterd & peer probe and create the volumes. But after glusterd restart. Also note that this still

Re: [Gluster-users] peer rejected but connected

Executing "gluster volume set all cluster.op-version "on all the existing nodes will solve this problem. If issue still persists please provide me following logs (working-cluster + newly added peer) 1. glusterd.info file from /var/lib/glusterd from all nodes 2. glusterd.logs from all nodes 3.

Re: [Gluster-users] heal info OK but statistics not working

1) one peer, out of four, got separated from the network, from the rest of the cluster. 2) that unavailable(while it was unavailable) peer got detached with "gluster peer detach" command which succeeded, so now cluster comprise of three peers 3) Self-heal daemon (for some reason) does not

[Gluster-users] high (sys) cpu util and high load

Hi I'm seeing quite high cpu sys utilisation and an increased system load the past few days on my servers. It appears it doesn't start at exactly the same time for the different servers, but I've not (yet) been able to pin the cpu usage to a specific task or entries in the logs. The cluster is

[Gluster-users] Slow performance of gluster volume

Hi all, I have a gluster volume used to host several VMs (managed through oVirt). The volume is a replica 3 with arbiter and the 3 servers use 1 Gbit network for the storage. When testing with dd (dd if=/dev/zero of=testfile bs=1G count=1 oflag=direct) out of the volume (e.g. writing at /root/)
