Bonding is just one particular case which HA handles. There are many other applications of HA.<br>Suppose you have 3 servers each exporting a storage brick and also an AFR volume of bricks from three servers, you can HA all the 3 AFR subvolumes and you will have availability of glusterfs till the last server is reachable.<br>

</div></div>I think the name of "HA" is mismatch. For replication is also "HA" when one of<br>
storage node went down.<br>
<br>
HA of gluster is more like bonding of multiple network interface，and I think<br>
it is no need for glusterfs, because we can do bonding!!<br>
