I have installed a new larger 40 gig drive in my system. I now wish to move /usr, which currently resides on its own drive and almost full, to the new 40 gig drive so it will be a directory under /.

this has been asked a number of times, one thread i found from searching is http://www.linuxquestions.org/questi...threadid=10636 should have everythign you need to know, if not just search again.

I guess I wasn't clear. in my first post. :-( /usr is currently residing on hdb. It is of course mounted as /usr. Now that I have a larger hda I want all the data from hdb moved to a directory called /usr on hda. I do not want to create another partition on hda. I have already run parted and enlarged / to take up the whole drive.

I want to eliminate the mount point /usr on hdb and remove the drive.

I'm new to this thing called linux so please excuse me if my terminology isn't exactly on.

I am assuming that I need to copy the contents of /usr to a temp directory, umount /usr and rename the temp dir to /usr. Only thing is I can't umount /usr, probably because files are in use -- it figures.

Any help is appreciated.

You won't be able to do this while you're running at level 3 or 5. There are too many processes that fire up and have open files when you're running in multiuser mode to allow this. (Crimeny, lsof tells me that I have nearly 3000 resources in use under /usr!) You're going to have to take the system into single user mode to do this. Then the process that you described will work. Take a look at the info page for cpio, specifically the section on copying directory structures. You can practice the directory copy a few times (/usr -> /scratch) until you're comfortable with how it works. Then you can go to single user and do the real thing. Don't forget to tweak /etc/fstab after you're certain that /usr has been successfully copied, prevent any mounting of old partition back onto it's original mount point.

Good luck,

Rick

Thanks to everyone who replied.

For the record here's what I ended up doing...

telinit 1
umount /usr
mount /dev/hdb1 /mnt/usrtemp -- I created usrtemp first
cd /mnt /usrtemp
cp * -ar /usr -- this copies the symbolic links too

delete the /usr mount line from fstab
reboot

Easy when you know how.

Thanks again
