Hi, I had a problem some time ago with 3.7.6 and freezing during heals, and multiple persons advised to use 3.7.11 instead. Indeed, with that version the freez problem is fixed, it works like a dream ! You can almost not tell that a node is down or healing, everything keeps working except for a little freez when the node just went down and I assume hasn't timed out yet, but that's fine. Now I have a 3.7.11 volume on 3 nodes for testing, and the VM are proxmox VMs with qCow2 disks stored on the gluster volume. Here is the config : Volume Name: gluster Type: Replicate Volume ID: e4f01509-beaf-447d-821f-957cc5c20c0a Status: Started Number of Bricks: 1 x 3 = 3 Transport-type: tcp Bricks: Brick1: ipvr2.client:/mnt/storage/gluster Brick2: ipvr3.client:/mnt/storage/gluster Brick3: ipvr50.client:/mnt/storage/gluster Options Reconfigured: cluster.quorum-type: auto cluster.server-quorum-type: server network.remote-dio: enable cluster.eager-lock: enable performance.quick-read: off performance.read-ahead: off performance.io-cache: off performance.stat-prefetch: off features.shard: on features.shard-block-size: 64MB cluster.data-self-heal-algorithm: full performance.readdir-ahead: on As mentioned, I rebooted one of the nodes to test the freezing issue I had on previous versions and appart from the initial timeout, nothing, the website hosted on the VMs keeps working like a charm even during heal. Since it's testing, there isn't any load on it though, and I just tried to refresh the database by importing the production one on the two MySQL VMs, and both of them started doing I/O errors. I tried shutting them down and powering them on again, but same thing, even starting full heals by hand doesn't solve the problem, the disks are corrupted. They still work, but sometimes they remount their partitions read only .. I believe there is a few people already using 3.7.11, no one noticed corruption problems ? Anyone using Proxmox ? As already mentionned in multiple other threads on this mailing list by other users, I also have pretty much always shards in heal info, but nothing "stuck" there, they always go away in a few seconds getting replaced by other shards.
