Is there a reason one can not mount a btrfs and it's byte-for-byte copy in parallel, or is the driver just acting silly?
Mini example: # dd if=/dev/zero of=fs1 bs=1 count=1 seek=$((1024*1024*1024-1)) # mkfs.btrfs fs1 # cp --sparse=always fs1 fs2 # mkdir 1 2 # mount fs1 1 -o loop # mount fs2 2 -o loop # touch 1/1 # ls 2 1 # cat /proc/mounts /dev/loop0 /tmp/test/1 btrfs rw,relatime 0 0 /dev/loop1 /tmp/test/2 btrfs rw,relatime 0 0 -- ivan -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
