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.

I've been running in that configuration for a couple months now with no problems. I have 6 data + 3 arbiter bricks hosting VM disk images and all three of my arbiter bricks are on one of the kvm hosts. > Can I use multiple arbiter for the same volume ? In example,

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

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

Ok. I have a 3rd host with Debian 12 installed and Gluster v11. The name of the host is arbiter! I already add this host into the pool: arbiter:~# gluster pool list UUID Hostname State 0cbbfc27-3876-400a-ac1d-2d73e72a4bfd gluster1.home.local Connected 99ed1f1e-7169-4da8-b630-a712a5b71ccd gluster2 Connected

But if I change replica 2 arbiter 1 to replica 3 arbiter 1 gluster volume add-brick VMS replica 3 arbiter 1 arbiter:/arbiter1 arbiter:/arbiter2 arbiter:/arbiter3 I got thir error: volume add-brick: failed: Multiple bricks of a replicate volume are present on the same server. This setup is not optimal. Bricks should be on different nodes to have best fault tolerant configuration. Use

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

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

So I went ahead and do the force (is with you!) gluster volume add-brick VMS replica 3 arbiter 1 arbiter:/arbiter1 arbiter:/arbiter2 arbiter:/arbiter3 volume add-brick: failed: Multiple bricks of a replicate volume are present on the same server. This setup is not optimal. Bricks should be on different nodes to have best fault tolerant co nfiguration. Use 'force' at the end of the command

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
