[lvm-devel] LVM2/tools lvconvert.c



CVSROOT:	/cvs/lvm2
Module name:	LVM2
Changes by:	jbrassow sourceware org	2010-07-13 21:53:08

Modified files:
	tools          : lvconvert.c 

Log message:
	Fix for bug 612311: Split of linear provides no error msg
	
	An unhandled condition allowed the command to terminate
	cleanly without a warning.  Added a check for the
	'--splitmirrors' argument to allow execution to the lower
	level function that has the check to see if the user is
	trying to split a linear device.  You should now see a
	message if you try to use --splitmirrors on a linear device.
