Not sure I understand this one – couldn’t find any docs for it.

What do the client logs say? Dumb question - Which logs are those? Could you share the exact steps to recreate this, and I will try it locally on my setup? I'm running this on a 3 node proxmox cluster, which makes the vm creation & migration easy to test. Steps: - Create 3 node gluster datastore using proxmox vm host nodes - Add gluster datastore as a storage dvice to proxmox * qemu vms use the gfapi to access the datastore * proxmox also adds a fuse mount for easy acces - create a VM on the gluster storage, QCOW2 format. I just created a simple debain Mate vm - start the vm, open a console to it. - live migrate the VM to a another node - It will rapdily barf itself with disk errors - stop the VM - qemu will show file corruption (many many errors) * qemu-img check <vm disk image> * qemu-img info <vm disk image> Repeating the process with sharding off has no errors. Also, want to see the output of 'gluster volume info'. I've trimmed settings down to a bare minimum. This is a test gluster cluster so I can do with it as I wish. gluster volume info Volume Name: datastore1 Type: Replicate Volume ID: 238fddd0-a88c-4edb-8ac5-ef87c58682bf Status: Started Number of Bricks: 1 x 3 = 3 Transport-type: tcp Bricks: Brick1: vnb.proxmox.softlog:/mnt/ext4 Brick2: vng.proxmox.softlog:/mnt/ext4 Brick3: vna.proxmox.softlog:/mnt/ext4 Options Reconfigured: performance.strict-write-ordering: on performance.readdir-ahead: off cluster.quorum-type: auto features.shard: on -- Lindsay
