First off - let me say I am not an administrator. I need to know if there is an easy way to increase my /boot partition. When I installed CentOS 6 after running 5, it was my oversight not to increase the /boot size. it's too small and I can't do yum updates. if it's not easy to actually increase it, is it safe to take a chunk in my root filesystem (like /new.boot or something) and just mount it as /boot from now on so it uses the space or is that not a good idea? I am sure I could easily copy the rpms/kernel stuff over to it and then unmounts the real /boot and mount this new area as /boot. Can you administrators let me know what you think of all this? Thanks in advance.
Hi,
Since a lot of people seem to say none of the above can be done, I'm starting to feel slightly unsure, but I though gparted could extend, shrink and move partitions while preserving data. You'd have to use the "live" version when operating on system partitions. 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
