I'm using ext3, and it's now RAID-6, so a little smaller:
Filesystem Size Used Avail Use% Mounted on
/dev/md9 5.9T 33M 5.7T 1% /archive
And slower:
Version 1.03 ------Sequential Output------ --Sequential Input- --Random-
-Per Chr- --Block-- -Rewrite- -Per Chr- --Block-- --Seeks--
Machine Size K/sec %CP K/sec %CP K/sec %CP K/sec %CP K/sec %CP /sec %CP
bertha 2G 186290 96 111105 75 262779 71 602.0 2
I've looked at, and tried XFS (and JFS) and keep coming back to ext3,
which I have on many, many servers and have never had an issue with it.
I have had problems with XFS, but that was about 2 years ago, so things
might have improved by then.
This is the biggest server I've setup so-far, it beats my previous record
of 3TB (which I have on 2 identical servers halfway round the world from
each other and they've been doing well for several months now).
After your comment about ext3 max FS size, I had a bit of a oo-er
situation so had to do a bit of looking to make sure I was OK, and it
seems that 16TB is the current limit, so OK there for a while, at least...
