Hi,
I've built an 11TB RAID5 array using fedora23 (soon to be fedora24) to be used for backup for a bunch of mail and web servers, and thought I'd inquire about the best filesystem to use.
I suppose I'm most familiar with ext4, although I understand xfs is the default filesystem during install now.
I've been doing this for more than ten years: massive backups with rsync and --link-dest.
I started with reiserfs and it went on for more than ten years without any problem. Then I rebuilt the machines and decided to move to ext4. Ironically enough, I got into a serious bug in ext4 online expansion that caused data corruption. It is now solved, of course. Today, I would go for ext4. I have just a couple of system still on reiserfs, with very old (read: proven and trusted) software versions.
Regards.
