For the special case of "100%" there is no difference. For values
less than 100% with a non-empty VG, the two are quite different

bingo!xfs_growfs can be used with the file system online, I'm pretty

I have a laptop that I put centos 7 on and I started out with a 30gig
partition. I resized the other part of the disk to allow more space for
centos. I then created an unformated partition in the available space, ran
pvcreate /dev/sda4
vgextend lvname /dev/sda4
lvextend -L 184.46G /de
Thanks guys for help!
Work is done, everything went fine ..
Have a nice day,
