I have one POWER7 machine that has been provided to me by IBM for testing
purposes and to host one of our buildds. I have performed a test installation
of openSUSE Tumbleweed on it.
Here's the partitioning scheme that is being used:
(parted) p
Model: Virtio Block Device (virtblk)
Disk /dev/vda: 42.9GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Disk Flags:
Number Start End Size Type File system Flags
1 1049kB 2097kB 1049kB primary boot, prep, type=41
2 2097kB 2163MB 2161MB primary linux-swap(v1) type=82
3 2163MB 18.9GB 16.7GB primary btrfs type=83
4 18.9GB 42.9GB 24.0GB primary xfs type=83
(parted)
Interestingly, /boot is part of the btrfs filesystem:
linux-mfl2:~ # mount | grep boot
/dev/vda3 on /boot/grub2/powerpc-ieee1275 type btrfs (rw,relatime,space_cache,subvolid=261,subvol=/@/boot/grub2/powerpc-ieee1275)
