Hello list, I'm not sure what to look for here, not sure if what I'm seeing is the actual "backlog" (that we need to make sure is empty while performing a rolling upgrade before going to the next node), how can I tell, while reading this, if it's okay to reboot / upgrade my next node in the pool ? Here is what I do for checking : for i in `gluster volume list`; do

Mine also has a list of files that seemingly never heal. They are usually isolated on my arbiter bricks, but not always. I would also like to find an answer for this behavior. -----Original Message----- From: gluster-users-bounces at gluster.org [mailto:gluster-users-bounces at gluster.org] On Behalf Of Hoggins!

Hello list, I have an issue on my Gluster cluster. It is composed of two data nodes and an arbiter for all my volumes. After having upgraded my bricks to gluster 3.12.9 (Fedora 27), this is what I get : ??? - on node 1, volumes won't start, and glusterd.log shows a lot of : ??? ???

Oh, and *there is* space on the device where the brick's data is located. ??? /dev/mapper/fedora-home?? 942G??? 868G?? 74G? 93% /export Le 02/05/2018 ? 11:49, Hoggins! a ?crit?: > Hello list, > > I have an issue on my Gluster cluster.

is possible to add an arbiter node on the client? Let's assume a gluster storage made with 2 storage server. This is prone to split-brains. An arbiter node can be added, but can I put the arbiter on one of the client ? Can I use multiple arbiter for the same volume ? In example, one arbiter on each client.

Hi, The existing syntax in the gluster CLI for creating arbiter volumes is `gluster volume create <volname> replica 3 arbiter 1 <list of bricks>` . It means (or at least intended to mean) that out of the 3 bricks, 1 brick is the arbiter. There has been some feedback while implementing arbiter support in glusterd2 for glusterfs-4.0 that we should change this to `replica 2 arbiter

Hi, I see gluster now recommends the use of an arbiter brick in "replica 2" situations. How large should this brick be? I understand only metadata is to be stored. Let's say total storage usage will be 5TB of mixed size files. How large should such a brick be? -- Sent from the Delta quadrant using Borg technology! Nux! www.nux.ro

Hello, I have a replica 2 GlusterFS 3.8.11 cluster on 2 Debian 8 physical servers using ZFS as filesystem. Now in order to avoid a split-brain situation I would like to add a third node as arbiter. Regarding the arbiter node I have a few questions: - can the arbiter node be a virtual machine? (I am planning to use Xen as hypervisor) - can I use ext4 as file system on my arbiter? or does it need

As long as the VM isn't hosted on one of the two Gluster nodes, that's perfectly fine. One of my smaller clusters uses the same setup. As for your other questions, as long as it supports Unix file permissions, Gluster doesn't care what filesystem you use. Mix & match as you wish. Just try to keep matching Gluster versions across your nodes. On 29 June 2017 at 16:10, mabi

Hi! I am using GlusterFS on CentOS7 with glusterfs-3.8.15 RPM version. I currently have a replica 2 running and I would like to get rid of the split-brain problem before it occurs. This is one of the possible solutions. Is it possible to and an arbiter to this volume? I have read in a thread from 2016 that this feature is planned for version 3.8. Is the feature available? If so, could you give

Hey, Did the heal completed and you still have some entries pending heal? If yes then can you provide the following informations to debug the issue. 1. Which version of gluster you are running 2. gluster volume heal <volname> info summary or gluster volume heal <volname> info 3. getfattr -d -e hex -m . <filepath-on-brick> output of any one of the which is pending heal from all

I must ask again, just to be sure. Is what you are proposing definitely supported in v3.8?

Hello, As you might have read in my previous post on the mailing list I have added an arbiter node to my GlusterFS 3.8.11 replica 2 volume. After some healing issues and help of Ravi that could get fixed but now I just noticed that my quotas are all gone. When I run the following command: glusterfs volume quota myvolume list There is no output... In the /var/log/glusterfs/quotad.log I can see the
