See https://gparted.org I would prefer boot up in single, and partition a new boot device, with the larger /dev/sda1, and whatever else lvm stuff, then copy the file systems across with dump or xfsdump or whatever, swap the devices and boot. this way the old disk is a safe backup. heck, /boot can be a SD card or USB stick :-p -- john r pierce, recycling bits in santa cruz ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

Supposedly the below tool should be able to handle LVM volumes, and is bootable from CD.

I was thinking the OP's situation was /boot is a reasonable size but just got filled up because it was not being monitored. And, as a result, he made yum sad. So now all he wants is to clean it up just enough to use other stuff, and then as mentioned before reconfigure grub2.cfg to keep only a couple of 3 kernels around. Not going to say that happened to me in ubuntu before.
