[Gluster-users] Continual heals happening on cluster

[Lindsay Mathieson]

gluster 3.7.10
Proxmox (debian jessie)

I'm finding the following more than a little concerning. I've created a 
datastore with the following settings:

    Volume Name: datastore4
    Type: Replicate
    Volume ID: 0ba131ef-311d-4bb1-be46-596e83b2f6ce
    Status: Started
    Number of Bricks: 1 x 3 = 3
    Transport-type: tcp
    Bricks:
    Brick1: vnb.proxmox.softlog:/tank/vmdata/datastore4
    Brick2: vng.proxmox.softlog:/tank/vmdata/datastore4
    Brick3: vna.proxmox.softlog:/tank/vmdata/datastore4
    Options Reconfigured:
    features.shard-block-size: 64MB
    network.remote-dio: enable
    cluster.eager-lock: enable
    performance.io-cache: off
    performance.read-ahead: off
    performance.quick-read: off
    performance.stat-prefetch: on
    performance.strict-write-ordering: off
    nfs.enable-ino32: off
    nfs.addr-namelookup: off
    nfs.disable: on
    cluster.server-quorum-type: server
    cluster.quorum-type: auto
    features.shard: on
    cluster.data-self-heal: on
    cluster.self-heal-window-size: 1024
    transport.address-family: inet
    performance.readdir-ahead: on



I've transferred 12 Windows VM's to it (gfapi) and am running them all, 
spread across three nodes.

"gluster volume heal datastore3 statistics heal-count" shows zero heals 
on all nodes.

but "gluster volume heal datastore4 info" shows heals occurring on 
mutliple shards on all nodes, different shards each time its called.
