How to resize /usr with resize2fs and LVM2
I am trying to increase the size of my /usr filesystem with resize2fs by doing the following:
umount /dev/vgname/usr -> I get can't unmount device is busy. So I use lsof /usr to see who is currently has the /usr fs in an open state and it is several things. So i tried to reboot come up in rescue mode and resize it but it is still busy to where I can increase it I was figuring that I would be able to start a shell before mounting the fs's and then do the resize but it seems like it still mounts them in rescue mode. I am just seeing if anyone else has ever had this issue before .
