[SOLVED] Home mount point

slayme40 · 11-11-2015, 11:12 PM

Hi I'm running a dual boot with opensuse 13.2 and windoze 10. I am running out of space on my home mount point. If I install a second hard drive and add a second home mount point on my new hard disk will I be able to have some of my files on one home mount point (sda7) and other data on the other home mount point (sdb something).

Note that sda7 and sdb-something aren't mount points. The directories where they are mounted, be it /home or /home2, are named mount points.

More precisely, in this command

Code:

mount /dev/sdb1 /home2

/home2 is the mount point.

Somebody else had a similar question ten years ago. I don't know if better tools exist today that allow you to combine two mounts easily.

Edit: UnionFS may well be your solution.

Just mount the new drive somewhere and symlink or bind mount your Pics or Pron dirs from your home onto it.

And how do I do that may I ask

This is so confusing. Is it possible to just mount my new hard drive as home2 and just keep what's on the original home on home and just add put all my new files on home2?
That is just type mount /dev/sdb1 /home2 and use home2 from now on.

you cannot mount 2 different harddisk partitions onto the same mount point. That is simply not possible. You can have only one home dir. And you need to find out what do you want to do with the other directory.

Calling it home2 will just confuse you further - so give it a meaningful name like 'data', and (as root) make a mountpoint for it (just an ordinary directory) at /mnt/data (or such) and set the ownership of that dir to your user.
Then mount the new drive on it, make some dirs to hold your data and create symlinks to them in your existing /home/user/ dir.

edit: another simpler way would be to just mount it directly into, say, /home/user/data - then no symlinks would be needed.

I think the OP wants to copy the old home to the new disk, then mount the new disk under /home. If so, this is not only possible, but also rather simple.

mount /dev/sdb1 /mnt/newhome
cd /home
find . | cpio -pdumva /mnt/newhome
umount /mnt/newhome
put sdb1 in fstab
mount -a

I don't know enough about the current configuration to suggest what to do with the old home.

So do I just type mount /dev/mnt/hdb1 home/user/data and I will have the entire 500gb 2nd hard drive for the home/user/data mount point as well as all the data in the original /home mount point? Do I have to put anything in fstab?

Code:

mount /dev/hdb1 /home/user/data

But earlier you said your device was named /dev/sdb1, which is much more likely, since "hdb1" refers to IDE drives that have been phased out for years.

If you want the new disk to be mounted each time you reboot, yes, you have to put something in /etc/fstab. I would copy an existing line in /etc/fstab and modify it so that it matches the new disk and the new mount point.

Just wondering: Did you create a filesystem on the new disk? If not:

Code:

mkfs -t ext4 /dev/sdbwhatever

will create an EXT4 filesystem, which is the most popular type these days.

chrism01 · 11-12-2015, 05:15 AM

Basically, although you have to create the dir first (as yourself) so it has somewhere to mount to.
(you prob meant sdb1, not hdb1 - that's the old school naming convention).
Obviously you have to issue the mnt cmd as root, then check you can access it ok as the normal user before you add it to /etc/fstab.

Obviously you need to create a filesystem 1st, same with any o/s
