It is true for raid 5 & 6. Raid 0, 1, and 10 are supposed to be production ready. I use raid 10 only with btrfs, anything else and I use zfs or mdadm.

My only gripe with btrfs is that I’ve had systems come down from a single drive failure in raid quite “often” when compared to other FS.

ZFS is a ram hog but I always could do a live resilvering without downtime.

Edit: wtf… It’s actually tar -?. I’m so disappointed

I’d really like to see how Germans manage their college essays with minimum word count.
