[lvm-devel] LVM2 tools/lvresize.c test/t-lvresize-usage.sh



CVSROOT:	/cvs/lvm2
Module name:	LVM2
Changes by:	wysochanski sourceware org	2008-04-02 12:17:31

Modified files:
	tools          : lvresize.c 
Added files:
	test           : t-lvresize-usage.sh 

Log message:
	Fix lvresize to dump stack if vg_lock_and_read() fails.
	
	Necessary because vg_lock_and_read() may fail silently if the vg_check_status() call fails.
	
	Also add lvresize tests.
