Doesn't look like there are any recent answers here on this subject, so I'll ask - What are people using for the file system? XFS/EXT3/EXT4? We are about to install 4.3 on 15k SAS disks RAID 10 CentOS 6
I'm using ext4 on an OpenSUSE 12.1 system with a 2TB volume with no problems. Performance is more than adequate too
