What is the best file system for a home NAS?

Question

Iron

I'm building a home NAS.
As storage media, I plan to take 2 x WD30EFRX (RAID 1) + 1 x ST750LX003 (for OS)

OS - presumably Fedora or Ubuntu.

Tell me which file system is better to choose for:

• RAID 1
• drive on which the OS will be

upd:
Recently, Btrfs was heavily advertised to me, but judging from the Wiki text:

Btrfs has been included in the main branch of the Linux kernel since version 2.6.29-rc,[3] but remains experimental and not ready for production use.

Should You Consider Btrfs?

Answer 1

The choice of fs depends on the content that you are going to store on it. For example, for a stack of small files, I would advise raiserfs, for storage, say XFS movies, for a system, of course, journaling ext4. Also, don't forget about LVM. the time will come and you will need to expand the space.

Answer 2

NAS will choose itself, in my opinion XFS

Answer 3

I've been keeping files on XFS for the fourth year, RAID5, 2.7TB in total now. There were no problems due to the fault of the FS, but UPS is needed, yes.
OS - out of habit ext4 (until February 2009 it was ext3) on a one and a half gig partition.
PS: why a separate disk, but such a healthy one, under the OS? Why not cut off a couple of GB from the mirror, raise another mirror there - already under the OS?

Answer 4

I quote: "Btrfs is considered stable, but there is still no tool for checking the file system and fixing errors", i.e. In fact, it's still a test. You need to decide for yourself how important the safety of the data stored on your NAS is. raid will save you from disk death, but not from the problems associated with the collapse of the file system.
If the data is not critical, then go ahead - experiment, and post the results of experiments, tests and benchmarks in the form of a post, it will be interesting to read.

Answer 5

I use ext4 over lvm for file cleaning and torrento rocking. A good option.
