Hi,
I'm having some difficulty finding a method to shrink my /home to expand my /. They both correspond to LVMs. It is my understanding that one cannot shrink a xfs filesystem. One must back it up (xfsdump), remove (lvremove) redefine it and then restore it back (xfsrestore).
Okay, I'm running into a problem where /home needs to be "unused". If tried going in to "maintance mode", but I ran into a problem with the mount command (after issuing a 'chroot /sysroot'). I then tried using SystemRescueCD to boot to, but it wouldn't mount my 32TB RAID USB drive (something about too big).
Any thoughts or suggestions?
What is the problem if you boot directly into maintenance mode? Then it should be possible to backup home to a remote destination, unmount /home, remove the home LV, expand /, recreate home and mount it, restore from backup and you're done. No need to use any SystemRescueCD or other tool.
