comment Split large log file WITHOUT keeping the original (splitting in-place)
I usually find with bzip2 that I often get 20 to 1 compression, so compress it, then use something to stream uncompress it, and chunk from there if you need to.

comment Can I mount a read-only btrfs volume across multiple machines?
I've wondered about using ceph in this way, after all, it is a real cluster file system. You can run it with just one server.

comment Is is possible to live sync two network drives?
The Ceph clustered file file system can do this. But in this case, you might want a solution from your NAS vendor. Details are always useful.

comment High Memory 64bit server, not using all ram
Yes, you are showing 0.1%wa, so it's not like you are wasting time hitting the disk, if you want to get more work out of these systems, have a look at a good book on tuning, and figure out where the bottleneck is, because it's not the disk.
