<div dir="ltr"><div><div>Have been testing failure mode by killing the gluster processes on a node (killall glusterd glusterfsd). <br><br>Pleasantly surprised how much smoother gluster has got at this since 3.5, heal takes a while but it no longer kills cluster performance. Probably helps that I'm using replica 3 now rather than replica 2.<br><br></div>However I managed to create a state where a file was being healed on all three nodes (probably y live migrating a VM while it was being healed). I didn't think that was possible without creating a split brain problem, but it eventually got all the way to being healed.<br><br><br></div>Is this the diff algorithm in play? is it comparing blocks on all three nodes using the ones that are identical across two or three nodes? If it encountered a block that was different on all three ndes would that result in split brain?<br><div><div><div><br><br clear="all"><br>-- <br><div class="gmail_signature">Lindsay</div>
