Multiple harddisks at same mount point?

[Senate]

Hello.

I have a debian box on which I wish to expand the storage space. Currently I have hdb1 mounted at /home.

Today I've have installed a large disk (hdd1) which I want to use for extending my /home folder. I have already created partition etc. Now I want to know if it is possible to mount this disk in my /home folder as weel making hdb1 and hdd1 acting as one large disk?

Should I just add

/dev/hdd1 /home ext3 defaults 0 0

to my /etc/fstab? Can two disks have the same mount point?

I did it last night!!!

You should use the LVM (logical volume manager). You should setup the actual /home partition and the new hdd to be prepared to work with LVM. then, the two partitions act as an unique partition that you can mount on /home.

To prepare LVM volume I've used the dian installation program. Surely there are dedicated tools, but I don't know how to use it! Cjeck a LVM how-to!!!

Can two disks have the same mount point?

You can "overlay" a mount point -- the last partition mounted will be on top; I seem to recall that it's possible for directories "underneath" to be visible and accessible when there's no naming conflict from "above". For example, I think if you have a /home mounted with just a /user1 subdirectory, and mount another /home with a /user2 subdirectory, both user directories will be there.

But the ordinary thing to do in this case is to simply make a separate sub-directory as a mount point. For example, to make a /home/downloads or /home/docs or something similar ...
