Hallo, linux-btrfs,

I want to change some TByte disks (at least one) from ext4 to btrfs. And I want "-d raid0 -m raid1". Is it possible to tell btrfs-convert especially these options for data and metadata?

Or have I to use "mkfs.btrfs" (and then copy the backup) when I want these options?

Viele Gruesse!
Helmut

The other alternative is to get hold of 3.3-rcX and the latest
userspace tools (currently in the "dangerdonteveruse branch, but should be in "master" very soon), and use the restriper after you've converted.

Hmmmm - I don't yet dare these experiments with really big disks ...

Viele Gruesse!
