[PVE-User] Proxmox VE 2.0: new layout of NFS directories (and how to fix)

[Flavio Stanchina]

I noticed that PVE 2.0 will now create subdirectories within NFS mounts, 
for example a directory called "dump" for backups or "template/iso" for 
ISO images. I guess this allows one to use a NFS mount for several types 
of storage, something that PVE 1.x didn't allow. Is this correct? I 
would have checked this myself, but today my 2.0 test server refuses to 
create or edit NFS mounts: is this a regression in 2.0 beta 3?

If you have existing NFS exports that you were using with PVE 1.x and 
you want to use them with 2.0 without moving files around or changing 
the mount points, you can create symlinks to let PVE 2.0 see the files. 
For ISO directories:
# mkdir /data/iso/template
# ln -s .. /data/iso/template/iso

For backup directories:
# rmdir /backup/pve/dump
# ln -s . /backup/pve/dump

rmdir is needed because it's likely that PVE has already created an 
empty "dump" directory. In my setup it didn't do so on the ISO directory 
because it's mounted read-only on the PVE servers (it's managed from 
another server).

Debugging is twice as hard as writing the code in the first place.
Therefore, if you write the code as cleverly as possible, you are,
by definition, not smart enough to debug it.
