<div dir="ltr">Hi Fajar,<div><br></div><div>(1) Understood, I was just trying to work out if mine was one.</div><div>(2) I've got it working with the client connecting to the server IP address, does this still have problems? One of the issues I have with LXC is knowing when an action is considered to be on the same machine as the host and when it's separate.</div><div>(3) My portability concern was around being able to migrate a container to a new host, so yeah, I would need to add the NFS share on the new host as well.</div><div>(4) For backups I read somewhere that if you tar a container with a bind mount you also tar the contents of the mount, so if I bind mount then I'll need to work out a way to remove the bind mount prior to running tar</div><div><br></div><div>Thanks for your help :-)</div><div><br></div><div>Matt</div><div> </div></div><div class="gmail_extra"><br><div class="gmail_quote">On 4 December 2015 at 12:54, Fajar A.

So don't be surprised if yours isn't one of them.</div><div><br></div><div>(2) IIRC it's NOT recommended to have an nfs client mounting nfs share from localhost (i.e. loopback nfs mount), At least in old kernels: <a href="https://lwn.net/Articles/595652/" target="_blank">https://lwn.net/Articles/595652/</a> .

If its THAT, then you'd always have to perform some level of adjustment anyway, with or without additional bind mounts.</div><div><br></div><div>If you mean "what happens when the nfs server is on another server", then the host can import the share on the SAME path as you're currently using, and bind-mount will continue to work (as long as the path and owner/permission is the same)</div><div><br></div><div>(4) you create a backup strategy that fits your needs.</div><span class="HOEnZb"><font color="#888888"><div><br></div><div>-- </div><div>Fajar</div></font></span></div></div></div>
