Why use lvextend/reduce over lvresize?

Is there a reason we would NOT want to use lvresize over lvextend or lvreduce when not spanning multiple volume groups?

Hi @mglassman ,

I don't see any technical difference between using lvresize over lvextend / lvreduce. It seems they have the same capabilities. The only thing I found, is that when you want to extend a LVM logical volume, if you write the wrong symbol (- instead +), you will lose data. So, it may be safer to use lvextend in that case, because you won't make any important mistake. But more than that, I don't see any relevant difference.

Regards,
Luis.
