Description

Running "lfs getstripe" on a directory only shows the simple filesystem default layout and not the root default layout that will actually be inherited by new files.

# lfs setstripe -p ssd /mnt/testfs
# lfs getstripe -d /mnt/testfs
stripe_count: 1 stripe_size: 1048576 stripe_offset: -1 pool: ssd
# mkdir /mnt/testfs/tmp/should_be_old
# lfs getstripe -d /mnt/testfs/tmp/should_be_old
stripe_count: 1 stripe_size: 1048576 stripe_offset: -1
