Bonjour,
I try to build a home nas to make a dlna server for audio, video and
pictures.
I have 2 disks for the data which I want to be mounted in raid1 (software).
I formated the two disks using btrfs
(mkfs.btrfs -m raid1 -d raid1 /dev/sda /dev/sdb)
It works but, up to now, I can't see the advantages of this file system
vs ext4 managed by mdadm.
One disadvantage is that it seems that monitoring the system is not
possible in case of disk failure for instance.
Illuminate me with your knowledge.
I'm no expert in Btrfs, but I wouldn't say there is much advantage in
using it for a media server, given that the snapshotting, subvolume
features, COW etc. aren't really going to matter. Media servers are
almost entirely read-dominated.
Other opinions are available of course.
