Hi,<br>
<br>
We have around 60 hosts and each of them acts as glusterFs clients as well as server.<br>
<br>
To achieve HA, my underatanding is that we can use Ganesha NFS alone (and not Kernel NFS) and for above 3.10 versions, the HA packages are not ready yet.<br>
<br>
So, I'm thinking if I can avoid HA by making each client acts as server for itself.<br>
<br>
i.e.,the server name specified while mounting is localhost.<br>

IIUC, you are planning to use gluster native client (via FUSE) mounts act as NFS server by exporting those mount paths via Kernel-NFS/NFS-Ganesha. If thats the case, yes it shall add a bit of overhead to the performance.<br>
<br>
Also without HA packages, wouldn't that NFS server become single point of failure to its NFS clients. How will you ensure the IPs used by that particular host migrates to another one.<br>
<br>
Thanks,<br>

So, if a host have issues, then it won't affect other hosts and no need for HA.<br>
<br>
But will there be any performance impact in having too many glusterFs servers?<br>
