There is no doc to my knowledge. I will write one, now that you pointed it out. ;)
Client-side heals are heals that happen from the GlusterFS client, as part of LOOKUP, sometimes even READ, [F]STAT, etc.
You can tell when a client did a heal if a corresponding log message appears in that client's log file (usually the ones with MSGID: 108026, although name heals aren't logged).
They are enabled by default.
To disable entry heal from clients for instance, you do #gluster volume set <VOL> cluster.entry-self-heal off
To disable entry heal from clients for instance, you do #gluster volume set <VOL> cluster.entry-self-heal off
To disable data self-heal from clients, you do #gluster volume set <VOL> cluster.data-self-heal off
If you want to prevent the client from doing self-heal altogether, you disable all three forms of client healing: data-self-heal, entry-self-heal and metadata-self-heal.
Server side heals are heals that are performed by the self-heal daemon. You will see log messages with MSGID: 108026 in glustershd.log when the self-heal-daemon performs a heal.
Server side heals happen in the following cases:
1) when you execute #gluster volume heal <VOL> full
2) when you execute #gluster volume heal <VOL>
3) when a brick that was previously down comes back up.
To disable server side heal, you need to disable the self-heal-daemon. You can do that with #gluster volume set <VOL> cluster.self-heal-daemon off
