Sorry, one more detail - I have my test setup so that both my scratch device
and my test device are partitions on my PMEM ramdisk.
export TEST_DEV=/dev/pmem0p1
export TEST_DIR=/mnt/xfstests_test
export SCRATCH_DEV=/dev/pmem0p2
export SCRATCH_MNT=/mnt/xfstests_scratch
function xfstests_init {
parted -s $xfstests_dev mktable msdos
parted -s -a optimal $xfstests_dev mkpart Primary 1 4GiB
parted -s -a optimal $xfstests_dev mkpart Primary 4GiB 7GiB
if [[ $test_fs == "xfs" ]]; then
mkfs.xfs -f $TEST_DEV
mkfs.xfs -f $SCRATCH_DEV
elif [[ $test_fs == "ext4" ]]; then
mkfs.ext4 -F $TEST_DEV
mkfs.ext4 -F $SCRATCH_DEV
elif [[ $test_fs == "ext2" ]]; then
mkfs.ext2 -F $TEST_DEV
mkfs.ext2 -F $SCRATCH_DEV
else
echo "Invalid test fs '$test_fs'"
fi
}
