In a replicated cluster, the client writes to all replicas at the same time. This is likely while you are only getting half the speed for writes as its going to two servers and therefore maxing your gigabit network. That is, unless I am misunderstanding how you are measuring the 60MB/s write speed. I don't have any advice on the other bits...sorry. Todd -----Original Message----- From:

I've mounted a gluster 1x2 replica through NFS in oVirt. The NFS share holds the qcow images of the VMs. I recently nuked a whole replica brick in an 1x2 array (for numerous other reasons including split-brain), the brick self healed and restored back to the same state as its partner. 4 days later, they've become inbalanced. The direct `du` of the /brick are showing different sizes by

Dear GlusterFS Engineer, I have questions that my glusterfs server and fuse client perform properly on below specification. It can write only *65MB*/s through FUSE client to 1 glusterfs server (1 brick and no replica for 1 volume ) - NW bandwidth are enough for now. I've check it with iftop - However it can write *120MB*/s when I mount nfs on the same volume. Could anyone check if the

Hi, I have a volume created of 12 bricks and with 3x replication (no stripe). We had to take one server (2 bricks per server, but configured such that first brick from every server, then second brick from every server so there should not be 1 server multiple times in any replica groups) for maintenance. The server was down for 40 minutes and after it came up I saw that gluster volume heal home0

Hi, all As the title I found that gluster fs 3.3 has the ability to change replica count in the official document: http://www.gluster.org/community/documentation/index.php/WhatsNew3.3 But I couldnt find any manual about how to do it. Has this feature been added already, or will be supported soon? thanks. Wang Li -------------- next part -------------- An HTML attachment was scrubbed...

hi all, I accidentally removed the brick directory of a volume on one node, the replica for this volume is 2. now the situation is , there is no corresponding glusterfsd process on this node, and 'glusterfs volume status' shows that the brick is offline, like this: Brick 192.168.64.11:/opt/gluster_data/eccp_glance N/A Y 2513 Brick 192.168.64.12:/opt/gluster_data/eccp_glance

I'm hoping that someone here can point me the right direction to help me solve a problem I am having. I've got 3 gluster peers and for some reason glusterd sill not start on one of them. All are running glusterfs version 3.4.0-8.el6 on Centos 6.4 (2.6.32-358.el6.x86_64). In /var/log/glusterfs/etc-glusterfs-glusterd.vol.log I see this error repeated 36 times (alternating between brick-0

Hello, I''m trying to build a replica volume, on two servers. The servers are: blade6 and blade7. (another blade1 in the peer, but with no volumes) The volume seems ok, but I cannot mount it from NFS. Here are some logs: [root@blade6 stor1]# df -h /dev/mapper/gluster_stor1 882G 200M 837G 1% /gluster/stor1 [root@blade7 stor1]# df -h /dev/mapper/gluster_fast

Hello, I am having trouble expanding a volume. Every time I try to add bricks to the volume, I get this error: [root at gluster1 sdb1]# gluster volume add-brick vg0 gluster5:/export/brick2/sdb1 gluster6:/export/brick2/sdb1 /export/brick2/sdb1 or a prefix of it is already part of a volume Here is the volume info: [root at gluster1 sdb1]# gluster volume info vg0 Volume Name: vg0 Type:

Hello, Recently I spent a bit time understanding rebalance since I want to know its performance given that there could be more and more bricks to be added into my glusterfs volume and there will be more and more files and directories in the existing glusterfs volume. During the test I saw something which I'm really confused about. Steps: SW versions: glusterfs 3.4.4 + centos 6.5 Inital

Hi guys, I have configured gluster fs in replication mode in two ubuntu servers. Windows users use samba sharing to access the mounted volume. Basically my setup is that client machines on each site connect to its local file server so it has the fattest connection. Two files servers are connected via VPN tunnel which has really high bandwidth Right now it is very slow to write files to the

Hi, I have a glusterfs 3.3.1 setup with 2 servers and a replicated volume used by 4 clients. Sometimes from some clients I can't access some of the files. After I force a full heal on the brick I see several files healed. Is this behavior normal?

Hi all? I do the following test? I create a glusterfs replica volume (replica count is 2 ) with two server node(server A and server B)? then mount the volume in client node? then? I shut down the network of server A node? in client node? I copy a dir?which has a lot of small files?? the dir size is 2.9GByte? when copy finish? I start the network of server A node? now?

hi all, as the title says - i'm looking to change a volume from dist/repl -> dist. we're currently running 3.2.7. a few of questions for you gurus out there: - is this possible to do on 3.2.7? - is this possible to do with 3.4.1? (would involve upgrade) - are there any pitfalls i should be aware of? many thanks in advance, regards, paul -------------- next part -------------- An

Yes, it's true. I've been up late hacking on Gluster (and Puppet-Gluster)... While waiting for my code to compile, patch review (*cough*), and for JMW (aka johnmark) to take care of a few todo items, I realized I had never written an IRC bot!! Now I never aspired to be the bot master that JoeJulian is, but I figured I needed this notch on my hacker belt... Therefore, I'd like to

Hi ,? I recenlty configured the 2 node replica glusterfs , and I am having couple of issues? 1. As soon ?as a I reboot the node2 , the glusterfs on node1 is not available but when I reboot/shutdown node1 the glusterfs is available on node 0 , so please let me know if you guys have encountered the same issue 2. I am not able to mount the glusterfs mount at the time of reboot I had to do manually

Hi guys: I have just installed gluster on a single instance, and the command: gluster volume create gv0 replica 2 server.n1:/export/brick1 server.n1:/export/brick2 returns with: "Failed to perform brick order check... do you want to continue ..? y/N"? What is the meaning of this error message, and why does brick order matter? -- Jay Vyas http://jayunit100.blogspot.com

Hi, I have a 2-node replica volume running with GlusterFS 3.3.2 on Centos 6.4. I want to shut down one of the gluster servers for maintenance. Any best practice that is to be followed while turning off a server in terms of services etc. Or can I just shut down the server. ?

Hi all How to ensure the new data write to other bricks, if one brick offline of gluster distributed volume ; the client can write data that originally on offline bricks to other online bricks ; the distributed volume crash, even if one brick offline; it's so unreliable when the failed brick online ,how to join the original distribute volume; don't want the new write data can't
