New hard drive plz help


I have 3 Partitions i want to put /usr on a new hard drive couldnt i just do this?

/dev/hda1 for /boot
/dev/hda2 for swap
/dev/hda3 for /

Coudlnt i just mount /dev/hdb to /mnt/hdb then

CP -R /usr /mnt/hdb

then add the mount entry in fstab and reboot? Or would this screw things up

that would screw things up.

I've done that before... it really screwed up the box.

cp -Rp SHOULD work.

I'd advise you to use a LiveCD for the remount phase... I assume you'll want to remove the contents of the old /usr first: otherwise it will still consume space in /.

my suggestion would be to mount the drive on a temporary mount point... copy everything from the old /usr to the new... then mount the new drive as /usr... make sure it works... then remove the mount temporarily, erase everything from the old /usr, and then remount /usr

this sounds right. mounting the "new" /usr over the existing /usr dir should render the "old" /usr inaccessible and allow you to make sure everything works properly, before you delete the old one for good.

While I agree with the above, one point is to be made: you'll have a hard time mounting and unmounting the active /usr on a system. Probably deleting too. So much runs from there. Fortunately mount is usually /bin/mount or you'd be truly up a creek.

Well i tried but didnt work.

CP -Rp /usr /mnt/hdb1

then edited fstab

/dev/hdb1 /usr ext3 defaults 0 1

Linux boots but doesnt go into X windows.

It wont let me just mount /dev/hdb1 as /usr and it wont let me umount /usr

Matir - good point. that's the reason for having a dedicated /bin and /sbin (as opposed to /usr/bin, etc.) :
