RE: remount md0 after disc failure
G'day Bob/others,
Not sure where the brain was as /home would be mounted under /root.
Let's test that when I started /home was under /root, I just mounted /home
on md0, when I rebooted it was empty! Why? ... because there was no /home on
md0 in the first place so mount must have created a new /home therefore it's
empty, yes?
If there was a /home with data on md0 then mount would not have had to
create it, yes? hmmm.
OK, let's try it, df, /home is mounted on /dev/md0. Check contents of /home
then umount /home, check /home directory, empty as expected. Reboot ...,
hmmm, /home is NOT! empty, why? .. df, home is mounted on /dev/md0.
So fstab is remounting /home, so should hda disc fail, & I put an image of
it back and reboot there's nothing to do, right?
What if the disk is not the same size/shape/colour would that change things?
Well I answered my own questions hopefully, lol, just the last one, any
ideas?

| After you reinstalled debian you would not have anything to unmount.
| You will have a clean installation. At that time you can mount your
| new volume on top of the empty /home directory and you should be
| fine.
|
| Me thinking now that perhaps you were going to create a disk partition
| during the debian install for /home and put some disk space there,
| then unmount that later. That is the only way I could see to have
| disk space to unmount later. But then that space would be wasted. No
| need to do that.

|
| Sure, it is fine to have OS and data on separate disks. A common
| configuration.
|
| But because of that choice I see that you come from a background where
| when you need to reinstall the os it means scrape the disk clean and
| start fresh. Therefore put your data on a separate disk. HP-UX,
| Redhat, others are certainly that way. There is no way to upgrade.
| You must scrape clean and install the new version fresh. But with
| Debian I have never needed to do that. I have always been able to
| keep the system up to date with a continous update forward. It is one
| of the reasons I like using debian.
|
| In any case, hope the discussion helps.
