> I would recommend looking at XFS. It's a very old filesystem but has a lot of quite modern features (and it performs better than ext4 for several workloads). I would second this. XFS is great. A few years ago I moved from JFS to XFS for bulk data storage because JFS is pretty abandoned these days. No issues at all with XFS, and never lost any data. Just make sure it's right for you before you use it (e.g. you cannot shrink XFS volumes as you can ext4)
