Hi,

I am having a problem with the vzdump backup. Here is the status I am getting when it is completed:

Looks like it is breaking at 101: Jun 30 17:30:02 INFO: mode failure - unable to detect lvm volume group

I read the forums and changed the code according to this:

while (my $line = <$fd>) {
if ($line =~ m|^\s*(\S+):(\S+):(\d+(\.\d+))M$|) {

But I am still getting the error. Would someone be willing to help me fix this?

Thanks,
