Remounting my HDD

[Atealtha]

I got two HDDs.

One is mounted / and other /usr
Is there a way to unmount my /dev/hdb2 on /usr and remount on something more conspicuous like /backup or something?

[sajchurchey]

well try

umount /dev/hdb2
mkdir /backup
mount /dev/hdb2 /backup

Then change your /etc/fstab to reflect this by changing the directories that it mounts to.

But it is a necessity to have a /usr directory I believe, and some of your symbolic links in /usr/bin and others may not work w/out it mounted where it's supposed to be.

wouldn't /usr also be on my hda1?

Yes it is in a sortof. You will have a /usr in your / but just like a floppy or cdrom it will be empty if the hdb2 partition is not mounted.

Here are the steps to move /usr back to the / partition. check to be sure your / partition has enough space for everything in /usr

Check your /etc/fstab to verify /usr partition.
(As root)
unmount /dev/hdb2
mkdir /mnt/backup
mount -t <fstype> /dev/hdb2 /mnt/backup
cp -R /mnt/backup/* /usr

Delete /usr entry from /etc/fstab

In reality you can stick the the files anywhere and create a link to /usr. But yes you do need a /usr. If you install applications the default location is usually /usr/local.

So what are you really trying to accomplish?
