RAID + LVM partition size

I made a software RAID 5, and placed lvm on top of it. The home partition should be around 500GiB, but Krusader says it is only 70GiB. I named the RAID md5 (to remind me of its level), yet it got somehow renamed to md127. So is everyting working as it should and Krusader is misreading partition sizes, or should I fix something?

Here's the output of lsblk:

The partitions /dev/sda1 /dev/sda2 and /dev/sda3 are ntfs used for Windwows 7, /home and / are btrfs and /boot is ext4 (btrfs said it is too small for regular btrfs partition).
