btrfs or ext4

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.

Thank you.
