tests: happy using of 4K backend devices When the backend device supports only 4K blocks (like ramdisk) we cannot use for testing any smaller blocksize. So recalc test for 4K extent size. We may possibly introduce one list extra test that can be executed on devices with 512b sectors to check lvm2 support those min extent sizes... 2018-05-12 16:58:13 +03:00			`vgcreate -s 4k "$vg" "${DEVICES[@]}"`

tests: test should clean devices it has created To be able to detect lvm2 command is not leaking some 'unexpected' device - remove all devices before test exits by its own command so test teardown now can check what was 'left' unexpectedly. 2016-12-11 12:18:44 +03:00
