[lvm-devel] LVM2/lib/metadata metadata.c

[wysochanski at sourceware.org]

CVSROOT:	/cvs/lvm2
Module name:	LVM2
Changes by:	wysochanski at sourceware.org	2009-10-05 20:02:30

Modified files:
	lib/metadata   : metadata.c 

Log message:
	Add pvcreate_params to vg_extend_single_pv.
	
	Should be no functional change.  If this parameter is set to NULL, just fail
	the extend if the device is not already a PV.  If non-NULL, try pvcreate_single
	before failing.  Note that pvcreate_single() handles the log_error in case
	of failure so we just return 0 if pvcreate_single() fails.
