Add a common way to establish a scsi_debug-based 4K drive for use by an LVM2 test (rather than using the traditional loop device). prepare_scsi_debug_dev currently assumes exclussive access to the scsi_debug module. Any script that tries to use prepare_scsi_debug_dev when scsi_debug is unavailable or already loaded into the kernel will be skipped. t-topology-support.sh shows how prepare_scsi_debug_dev function can be used repeatedly (within a script) to test LVM2 ontop of a ramdisk-based SCSI device w/ arbitrary scsi_debug features.

Substantial rework of the functional test support code. Some new features: - somewhat neater, more consistent and more readable output - possible to set any lvm.conf value: aux lvmconf "section/key = value" - LVM_TEST_NODEBUG to suppress the (lengthy) "## DEBUG" output - back-substitution on test output ($TESTDIR/$PREFIX -> @TESTDIR@/@PREFIX@) - support code moved from test/ to test/lib/ --> less clutter

Refactor the test utilities, dropping the legacy test-lib.sh and curtailing lvm-utils.sh. Clears up lots of unused code, should have little observable impact (it does change test directory layout slightly).

Change default alignment of pe_start to 1MB. The new standard in the storage industry is to default alignment of data areas to 1MB. fdisk, parted, and mdadm have all been updated to this default. Update LVM to align the PV's data area start (pe_start) to 1MB. This provides a more useful default than the previous default of 64K (which generally ended up being a 192K pe_start once the first metadata area was created). Before this patch: # pvs -o name,vg_mda_size,pe_start PV VMdaSize 1st PE /dev/sdd 188.00k 192.00k After this patch: # pvs -o name,vg_mda_size,pe_start PV VMdaSize 1st PE /dev/sdd 1020.00k 1.00m The heuristic for setting the default alignment for LVM data areas is: - If the default value (1MB) is a multiple of the detected alignment then just use the default. - Otherwise, use the detected value. In practice this means we'll almost always use 1MB -- that is unless: - the alignment was explicitly specified with --dataalignment - or MD's full stripe width, or the {minimum,optimal}_io_size exceeds 1MB - or the specified/detected value is not a power-of-2
