[gentoo-user] Re: Moving root filesystem to a new partition [SOLVED]

[Alan E. Davis]

I found the email from some years ago, advising to bind mount / and copy /dev to the new partition from the bind mounted / partition.  It worked again this time.  Thank you again.

Can someone tell me what steps are necessary to move the / filesystem to a new partition?  I recall someone helping me with this before, but cannot find the email.  The oldest of three drives on my system had my / partition, /dev/sdc1.  One day recently, that partition became inaccessable.  After quickly installing Ubuntu on a different drive, that root partition eventually showed up again. 

So I've been able to boot Gentoo again off the separate /boot partition on /dev/sda1.  I need to move that / partition.  I have several other partitions mounted off this one, mainly as /usr and maybe /usr/local/, and some storage partitions mounted to my home directory. 

I copied the root (/) partition with the new partition at /dev/sdb5 mounted as /newroot, using
    # cp -ax / /newroot

I checked that /proc, /dev, and /sys are there, and empty.  I recall there are some other steps necessary.  I changed /etc/fstab, and the grub2 grub.cfg from ubuntu, the entry for this kernel.  The boot stalls at a certain point.  

May I ask what steps are necessary to do this?

Thank you,
