Dear gluster experts, I want to ask a question about how to monitor active mounted client for glusterfs. Since I want to known how many clients mount a volume and I also want to known the clients hostname/ip. I walk through the glusterfs admin guide and don't know how. Any one helps? -- Yongtao Fu -------------- next part -------------- An HTML attachment was scrubbed... URL:

We ran a load test using glusterfs and were able to deliver mail (I can't remember specifically how much per second, maybe 100 messages per second?) without any issues. We did use the glusterfs fuse client and not nfs, and used regular maildir. We developed a mail bot cluster that would deliver mail, and simultaneously receive and delete it with pop and IMAP and we ran into zero issues. We

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 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

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:

for all three nodes: Brick1: gluster-0-0:/mseas-data-0-0 Brick2: gluster-0-1:/mseas-data-0-1 Brick3: gluster-data:/data Which node are you trying to mount to /data? If it is not the gluster-data node, then it will fail if there is not a /data directory. In this case, it is a good thing, since mounting to /data on gluster-0-0 or gluster-0-1 would not accomplish what you need. To clarify, there

Dear folks, I've been tried to use replicated stripped volumes with 3.3. unsuccessfully due to https://bugzilla.redhat.com/show_bug.cgi?id=861423 and I then proceed to try 3.4.0qa5. I then find out that the bug was solved and I could use replicated stripped volume with the new version. Amazingly, write performance was quite astonishing. The problem I'm facing now is in the read process:

Hi, dear glfs experts: I've been using glusterfs (version 3.2.6) for months,so far it works very well.Now I'm facing a problem of adding two new bricks to an existed replicated (rep=2) volume,which is consisted of only two bricks and is mounted by multiple clients.Can I just use the following commands to add new bricks without stopping the services which is using the volume as motioned?

Hello Alessio and Gordon, thank you for answers. Dsync-based architecture looks promising, but I would preffer to stay with GlusterFS for now as I also use it as a storage for other components. So director is the way to go, I don't want to setup more than two nodes to keep this setup as simple as possible - so I will probably update to 2.2.19 and have director and backend on the same servers

Hello Is it possible to take advantage of copy-on-write implemented in btrfs if all bricks are stored on it? If not is there any other mechanism (in glusterfs) which supports CoW? regards -- Maciej Ga?kiewicz Shelly Cloud Sp. z o. o., Sysadmin http://shellycloud.com/, macias at shellycloud.com KRS: 0000440358 REGON: 101504426 -------------- next part -------------- An HTML attachment was

Hello, I have recently setup mailserver solution using 2-node master-master setup (mainly based on MySQL M-M replication and GlusterFS with 2 replica volume) on Ubuntu 14.04 (Dovecot 2.2.9).

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, 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 Reference: http://support.zresearch.com/community/documentation/index.php/Gluster_3.1:_Installing_GlusterFS_on_OpenSolaris I have found this guide to be too brief/terse, and have endeavoured to improve it via more of a recipie/howto approach - and possibly misunderstood the intent of the brief directions in the process. Please advise if there are any errors? Once the procedure is

Good afternoon, I am playing around with GlusterFS 3.1 in CentOS 6 virtual machines to see if I can get of proof of concept for a bigger project. In my setup, I have 4 GlusterFS servers with two bricks each of 10GB with XFS (per your quick-start guide). So, I have a total of 8 bricks. When bu I have no problem with distributed-replicated volumes. However, when I set up a striped replicated
