[Xen-devel] OSSTest RFC: ts-xen-build-prep, lvextend1(), don't call lvextend if "-l 0"

["Hu, Robert" <robert.hu@xxxxxxxxx>]

Hi,

lvextend will report error if doing with "-l 0".
So I propose to add an judgment regarding $vg_more_free_pe.

diff --git a/ts-xen-build-prep b/ts-xen-build-prep
index 9a3b523..f1d1255 100755

         overall_limit_pe(\$vg_more_free_pe);
         $more_pe += $vg_more_free_pe;
-        target_cmd_root($ho, "lvextend -i1 -l +$vg_more_free_pe $lv");
+        target_cmd_root($ho, "lvextend -i1 -l +$vg_more_free_pe $lv") 
+               if $vg_more_free_pe != 0;
     }

Best Regards,
