my math was wrong:
sizeof(struct btrfs_chunk)=80
so the maximum number of disk is: (2048/2-80)/32+1 = 30
Does make sense putting some warning in btrfs kernel module, and in some btrfs
command like:
- btrfs fi show
- btrfs dev add
and in the wiki ? 30 device are a big number, however not unreachable...
