some principal questions concerning btrfs and layout

Lentes, Bernd
Hi,

i have to install two pc's for our bioinformatics and will use Ubuntu 16.04.
I'd like to use btrfs. Some questions:

is it a good idea to have folders like /var/log, /usr/local or /var/lib on subvolumes ?
Suse does it that way. Advantage would be that if i make a snapshot from /
(e.g. before configuration changes), databases or logfiles would not be
snapshotted. So i don't have to be afraid of loosing database inserts or new entries in the
logfiles if i restore the snapshot.

I read an article about btrfs in a german computer journal. But it's a bit outdated.
Is it still necessary to balance the subvolumes ?
It recommends to do it regulary.


Bernd

I think you're being sarcastic, right? :)

Empty message body, over-long signature, and generally a mess, was my
impression.
