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

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.

I'm pretty sure that you can only have one arbiter per subvolume, and I'm not even sure what the point of multiple arbiters over the same data would be. In my case, I have three subvolumes (three replica pairs), which means I need three arbiters and those could be spread across multiple nodes, of course, but I don't think saying "I want 12 arbiters instead of 3!" would be supported. -- Dave Sherohman

Yes but I want to add.

OK, great. So basically just install the gluster server on the new node(s), do a peer probe to add them to the clust...

If you create a volume with replica 2 arbiter 1 you create 2 data bricks that are mirrored (makes 2 file copies) + you create 1 arbiter that holds metadata of all files on these bricks. You "can" create all on the same server, but this makes no sense, because when the server goes down, no files on these disks are accessible anymore, hence why bestpractice is to spread out over 3

Still getting error pve01:~# gluster vol info Volume Name: VMS Type: Distributed-Replicate Volume ID: e1a4f787-3f62-441e-a7ce-c0ae6b111ebf Status: Started Snapshot Count: 0 Number of Bricks: 3 x 2 = 6 Transport-type: tcp Bricks: Brick1: gluster1:/disco2TB-0/vms Brick2: gluster2:/disco2TB-0/vms Brick3: gluster1:/disco1TB-0/vms Brick4: gluster2:/disco1TB-0/vms Brick5: gluster1:/disco1TB-1/vms

Right now you have 3 "sets" of replica 2 on 2 hosts.In your case you don't need so much space for arbiters (10-15GB with 95 maxpct is enough for each "set") and you need a 3rd system or when the node that holds the data brick + arbiter brick fails (2 node scenario) - that "set" will be unavailable. If you do have a 3rd host, I think the command would be:gluster volume add-brick VOLUM...

Hi folks, I'm troubled moving an arbiter brick to another server because of I/O load issues. My setup is as follows: # gluster volume info Volume Name: myvol Type: Distributed-Replicate Volume ID: 43ba517a-ac09-461e-99da-a197759a7dc8 Status: Started Snapshot Count: 0 Number of Bricks: 3 x (2 + 1) = 9 Transport-type: tcp Bricks: Brick1: gv0:/data/glusterfs Brick2: gv1:/data/glusterfs Brick3:

Ok. I got confused here! For each brick I will need one arbiter brick, in a different partition/folder? And what if in some point in the future I decide to add a new brick in the main servers? Do I need to provide another partition/folder in the arbiter and then adjust the arbiter brick counter? --- Gilberto Nunes Ferreira Em ter., 5 de nov. de 2024 ?s 13:22, Andreas Schwibbe

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

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

Your add-brick command adds 2 bricks 1 arbiter (even though you name them all arbiter!) The sequence is important: gluster v add-brick VMS replica 2 arbiter 1 gluster1:/gv0 gluster2:/gv0 arbiter1:/arb1 adds two data bricks and a corresponding arbiter from 3 different servers and 3 different disks,? thus you can loose any one server OR any one disk and stay up and consistent. adding more bricks
