similar to: How to ensure the new data write to other bricks, if one brick offline of gluster distributed volume

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

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

I've been looking into using Gluster to replace a system that we currently use for storing data for several thousand users. With our current networked file system, each user can create volumes and only that user has access to their volumes with authentication. I see that Gluster also offers a username/password auth system, which is great, but there are several issues about it that bother me:

Hi All, I am facing issues restarting the gluster volume. When I start the volume after stopping it, the gluster fails to start the volume Below is the message that I get on CLI /root> gluster volume start _home volume start: _home: failed: Commit failed on localhost. Please check the log file for more details. Logs says that it was unable to start the brick [2013-08-08

Hello, I'm testing a two nodes glusterfs distributed cluster (version 3.3.1-1) on Debian 7. The two nodes write on the same iscsi volume on a SAN. When I try to write an 1G file with dd, I have the following results : NFS : 107 Mbytes/s Gluster client : 8 Mbytes/sec My /etc/fstab on the client : /etc/glusterfs/cms.vol /data/cms glusterfs defaults 0 0 I'd like to use the gluster

I see references to the Gluster Management Console in some of the older (3.0 and 3.1) documentation. Is this feature available in version 3.4 as well? If so, could someone point me to documentation on how to access? Thanks. -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi all I have a glusterfs cluster underpinning a KVM virtual server in a two host setup. Today the cluster just froze and stopped working. I have rebooted both nodes, brought up the storage again. I can see all the vm files there but when I try to start the vm the machine just hangs. How can I see if gluster is trying to synchronise files between the two servers? thanks Shaun -------------- next

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

Has anyone ever ran into a problem in which PHP's stat() call to a file on a Gluster-backed volume randomly fails, yet /usr/bin/stat never fails? Running strace against both reveals that the underlying system calls succeed. I realize this is probably a PHP problem since I cannot replicate with a non-PHP-based script; however, was hoping someone on this list might have seen this before. RHEL

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

Hi everyone, I've got glusterfs-server/glusterfs-client version 3.4.0final-ubuntu1~precise1 (from the semiosis PPA) running on Ubuntu 13.04. I'm trying to share ZFS (ZFS on Linux 0.6.2-1~precise from the zfs-stable PPA) using GlusterFS. When creating the ZFS filesystem and the Gluster volume, I accepted all the defaults and then: - I enabled deduplication for the ZFS filesystem (zfs set

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...

Hey james and JMW: Can/Should we schedule a google hangout where james spins up a puppet-gluster based gluster deployment on fedora from scratch?

Hi, I have a 2-node gluster with 3 TB storage. 1) I believe the "glusterfsd" is responsible for the self healing between the 2 nodes. 2) Due to some network error, the replication stopped for some reason but the application was accessing the data from node1. When I manually try to start "glusterfsd" service, its not starting. Please advice on how I can maintain
