I need to create a file server using Ubuntu Server 13.10 with the following specifications:

  • 1 80Gb HDD:
    • grub boot manager
    • System files
    • apache server files
  • 2 identical 1000GB HDDs:
    • RAID 1 array for redundancy (/dev/md0)
    • files that will be accessible via FTP
    • home folders for all users on the system with those said files

Here's the issue I'm having:

While installing Ubuntu Server 13.10, I forgot to set the RAID array (/dev/md0) to be mounted as the home folder. I finished configuring everything about the FTP server, apache, ssh and other services.

Now I noticed that the RAID Array was not being used at all,

Every solution I look at says to essentially reinstall everything, and start over. I'd rather not do that.

How do I set /dev/md0 to be mounted as a home partition without reinstalling the system?

  • @ElliottFrisch would you mind to be a bit more precise about how to add the /dev/md0 to my fstab saying that it should be mounted as /home. Is it '/dev/md0 /home ext4 defaults 0 0' ? or something else?

    @GeorgeStocker I know that, but the solution came first via comments, which I cannot mark as accepted, but now as Elliott posted a answer I can do it, thanks

To move your /home partition (which is a risky thing to do), you will need to -

First, format your new partition -

mkfs.ext4 /dev/md0

Then, add "/dev/md0" to your "/etc/fstab". Something like -

/dev/md0     /home     ext4     defaults     0     0

Then (the "p" is for preserve permissions)

tar cfp /home.tar /home

Next, 

rm -rf /home && mkdir /home && mount /home

Finally, 

tar xvvf /home.tar

Of course, if it doesn't work you will need to reinstall your system.

1st answer really helped me but when I tried to do "mount /home",

mount: wrong fs type, bad option, bad superblock on xxx.xxx.xxx.xxx:/directory, missing codepage or helper program, or other error

this error occurred.

So I did "mount /dev/md0 /home" and then it worked.
