It fails for 1k PE now. Patch adds log_region_size into allocation habdle struct and use it in _alloc_parallel_area() for proper log size calculation instead of hardcoded 1 extent - which can fail. Reproducer for incorrect log size calculation: DEV=/dev/sd[bcd] pvcreate $DEV vgcreate -s 1k vg_test $DEV lvcreate -m1 -L 12M -n mirr vg_test https://bugzilla.redhat.com/show_bug.cgi?id=477040 The log size calculation is mostly copied from kernel code.
