I do have 3 2tb drives with lvm2 on them recently I did resize some partitions (i didn't resize the vg - one drive one vg here) but I use lvresize -L ±nnG vg/lv to add exactly nn GB to desired lv an than online grow with resize2fs /dev/vg/lv
I did this more than once and never encountered any problem.
