[Gluster-users] NFS availability

[glusterzhxue]

Thanks. But if we use NFS even plus software like keepalived, we 'll lose the load balance of gluster. All traffic from clients will firstly reach in and finally flow out from NFS mount server. It becomes a bottleneck.

Hi,


You can use software like keepalived to manage a floating IP.


So, you can get an IP say 10.1.1.3 and it will float between your host 1 and host 2. 
Only one host at a time has the IP 10.1.1.3. If host 1 dies, host 2 can assume the floating IP.


You'll mount your NFS against the floating IP so the NFS mount still works even if one of the hosts dies.

Hi all,
As is known to us all, gluster provides NFS mount. However, if the mount point fails, clients will lose connection to Gluster. While if we use gluster native client, this fail will have no effect on clients. For example:
mount -t glusterfs host1:/vol1  /mnt

If host1 goes down for some reason, client works still, it has no sense about the failure(suppose we have multiple gluster servers).  However, if we use the following:
mount -t nfs -o vers=3   host1:/vol1 /mnt

If host1 failed, client will lose connection to gluster servers.

Now, we want to use NFS way. Could anyone give us some suggestion to solve the issue?

Thanks
