Tried btrfs à long time ago. Snapshots Can be great for OS Drive. But for data storage nothing Can Beat mdadm+lvm2. Big problem with btrfs : you can't know how much space is still available. (At the Time i checked it at least.)

@hoper @martin You can use btrfs filesystem df for example to know how much space is available (or used). or btrfs filesystem du to get details about a particular file.

@daftaupe @martin
Seems that things change, but according to the FAQ, there are still some issues with this matter (know how much Space left and use it)

Il still think that mixing réplication (raid) and file system is a very bad idea.

@hoper @martin Well I'm using it and liking it. I never liked lvm2 and mdadm. That's the beauty of having different alternatives.

@daftaupe @martin
With how many disk ? Did you already Lost a drive or two ? WhatsApp happens then ?
Already loose 2 drives on a raid5 with mdadm and manage to get back all data. (One drive was really out of order, the other one was just suddenly disconected)

@hoper @martin Good for you but I make backups, so I'm not afraid of losing disks :D which is really easy using btrfs send/receive feature.

Backups are Always needed of course. But it's a "last ressort solution" because when you restore you loose data... Maybe a day of work if you backup every night. So, be able to loose disks without any impact (notre even the need to umount the filesystem) is important.
