Survey F2FS(Flash Friendly File System)

[mocchira]

Currently we'd recommend LeoFS users using xfs where to store raw data files,
but F2FS might become more suitable one when using SSD.
let's check it out!

Have you evaluated btrfs before?

It seems to be good fs, I've read as the follows:

• Web site: Project Brtfs , Brtfs Wiki

Let we survey it, too.

Personaly I did it on Ubuntu12.04(v3.5).
As you may know, Since btrfs is still under heavy development status,
I often encountered unpredictable performance degradations AND crashes :(
but int the near future, I hope it will become de fact standard :)

Ubuntu is always 6+ months behind unfortunately.

[mocchira]

Latest v3.8 still have many problems for example like this,
So I will evaluate it if I have spare time :)

[essen]

Yeah I suppose for something that's mostly writing and few reading it's not good enough yet.

We use ZFS on Illumos which has both an ARC (in memory cache) and L2Arc (second level SSD cache). Leo works exceptionally well on this setup - with a very very high cache hit rate in the Arc.

We does not plan to survey `F2FS', yet. So I've closed this issue.
If we decided to start to survey it, we'll reopen this issue.
