comment Server hacked; how?
Is your server up-to-date? Commonly, self-installed CMSes which are not up-to-date (or extensions thereof) are the reasons for this.

comment NFS: client does not see new files created on server (caching?)
Because I mount the "/media/data" export as "/data" on the client (as you can see in the posted fstab). The NFS share works in principle. There is just the problem with showing updated files.

comment telnet cannot connect to port without firewall
We should tackle all this in chat. We should also find out who sends the network unreachable errors. Are you using virtualization on the server? Once solved, I will either post an answer or just delete this answer since it is not an actual answer. Should've started the chat right away.

comment Slow sudo and ssmtp (hosts file wrong?)
You're trying to fix the problem and jumping to conclusions without doing any diagnoses... I agree that such timeouts may very well come from name resolution trouble... Try a tcpdump on port 53 for example to see if it's doing DNS lookups that generate errors or the like: tcpdump -i lo port 53, tcpdump -i eth0 port 53...

comment VMware, LVM & Linux: Expanding a volume… temporarily, and without downtime
It's simply a question of volume. Say the filesystem has 40G, and they want to test stuff and temporarily need 80G. I don't want to say those additional 40G permanently goodbye since they don't need it permanently. OS is Linux as I said, more specifically SLES. Filesystems are usually ext3.

comment VMware, LVM & Linux: Expanding a volume… temporarily, and without downtime
Whether they are thin- or thick-provisioned you can always add/remove them on the fly from the OS, that is for sure. The advantage of an additional LVM layer is that you can add another VMDK on-the-fly by expanding the filesystem using a VMDK even if it comes from a different LUN (ok, you can also kind-of concatenate VMDKs). But all these insights still don't solve the main question which is how you can completely transparently expand and again later shrink a virtualized filesystem. The problem is the filesystem itself in the end. Maybe then simply the fact of using ext is the problem.
