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 /dev/lvname/root
I find it easiest to do lvextend -l 100%VG /dev/lvname/rootI find it easiest to do lvextend -l 100%VG /dev/lvname/root. (Then, if practical, and since it's a laptop, I'm guessing it's not a production machine), reboot from a livecd or whatever and doing e2fsk -f /dev/lvmname/root
I don't know if it will solve your issue, but may be worth trying.
I found this:
# lvextend -l +100%FREE /dev/myvg/testlv
doing a search. What's the difference between 100%VG and 100%FREE?
Thanks,

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, e.g., (50% of VG) != (50% of the free space in VG).

Thanks. This is the first time I'm worked with the lvm commands. I thought VG was a typo for GB, but I see in the help commands for lvm: lvdisplay and vgdisplay - vg is volume group.
