...The reason we are also looking into gluster is that we like that it uses standard components and that we can prevent forklift upgrades every 5,6,7 years by replacing a few bricks each year. Next to providing storage for home directories we would like to also use the hosts to run VM's in a hyperconverged setup (with their storage as an additional gluster volume on those bricks).

...t4, so I cannot comment on XFS. We use the fuse mount, because we are lazy and haven't upgraded to libgfapi.? I hope to start a new cluster with to libfgapi shortly because of the better performance. Also we use a localhost mount for the gluster driveset on each compute node (i.e. so called hyperconverged). So the only 'gluster' only kit is the lightweight arb box. So those VMs in the gluster 'pool' have a local write and then only 1 off-server write (to the other gluster enabled compute host), which means pretty good performance. We use the gluster included 'virt' tuni...

Hi, Why do you need to replace your existing solution? If you don't need to scale out due to the capacity reasons, the async NFS server will always outperform GlusterFS Ondrej ----- The information contained in this e-mail and in any attachments is confidential and is designated solely for the attention of the intended recipient(s).

That really isnt an arbiter issue or for that matter a Gluster issue. We have seen that with vanilla NAS servers that had some issue or another. Arbiter simply makes it less likely to be an issue than replica 2 but in turn arbiter is less 'safe' than replica 3. However, in regards to Gluster and RO behaviour The default timeout for most OS versions is 30 seconds and the Gluster

Hi, We are looking into replacing our current storage solution and are evaluating gluster for this purpose. Our current solution uses a SAN with two servers attached that serve samba and NFS 4. Clients connect to those servers using NFS or SMB. All users' home directories live on this server. I would like to have some insight in who else is using gluster for home directories for about 500
