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. KM
There is no easy way to increase the /boot partition. One can try to build another /boot partition and use that but that isn't simple either and prone to problems if the /boot is outside of where that particular BIOS can intepret (aka embedded in an LVM) or jump to.
I have found the simpler method is usually: dump the disks to backup, reinstall the system with 500 to 1000 MB /boot and restore from backups.
