Update tests Indent Shell improvements - use internal function for checks Use PVs in "" (LV and VG cannot have spaces) Several test very starting 'dmeventd' without annoucing it via prepade_dmeventd. Fix some of test actually. 2012-03-16 17:00:05 +04:00			`#!/bin/sh`

When resizing LVs, always round in the safe direction, regardless of whether we were called as lvresize or lvreduce. 2011-09-15 22:51:11 +04:00			`#`
