The dasd type of disks seem not be recognized by rear:
# parted /dev/dasda print
Model: IBM S390 DASD drive (dasd)
Disk /dev/dasda: 7385MB
Sector size (logical/physical): 512B/4096B
Partition Table: dasd
Disk Flags:
Number Start End Size File system Flags
1 98.3kB 420MB 419MB ext2
2 420MB 6862MB 6442MB ext4
3 6862MB 7385MB 523MB linux-swap(v1)
and after running rear savelayout we have:
# cat ./var/lib/rear/layout/disklayout.conf
# Filesystems (only ext2,ext3,ext4,vfat,xfs,reiserfs,btrfs are supported).
# Format: fs <device> <mountpoint> <fstype> [uuid=<uuid>] [label=<label>] [<attributes>]

Now the first part is also created with the fix:

# Partitions on /dev/dasda
