BTRFS & LVM
Hi, I was very excited when I realised, that Netgear is now using btrfs. Mainly because it would help a lot when changing disk in a raid0 without the need of destrying the complete raid. (I dont ...
What kind of RAID-0 volume would you want? A separate one for each disk? with that it would be quick to create a new volume on a new disk that you add. Swapping disks out isn't meant for backups. It's meant for replacing a dead disk or a disk you no longer wish to use (with a higher capacity one).
I think you meant md raid not LVM RAID. We are not using LVM. OS4 used EXT4 on top of LVM on top of md raid. Now we use BTRFS on md raid.
While the BTRFS filesystem is stable, BTRFS level RAID is still quite experimental (especially RAID5 and RAID6) in my personal view and I would not trust it. Whereas md raid has been around for over a decade and is very mature.
As for what we will do in the future you will have to wait and see.
