I have made a directory: sudo mkdir /ssd, the directory was supposed to be mounted to a raid array called md3. This was done by adding /dev/md3 /ssd auto defaults 0 0 to fstab. Then after a while where I had used the directory, I realized that I had forgotten to run sudo mount -a - and then I did, and now the data is gone. I tried to uncomment the line in fstab and run sudo mount -a but that didn't get back my data. What can I do!?

CONTENT OF FSTAB:

proc /proc proc defaults 0 0
none /dev/pts devpts gid=5,mode=620 0 0
/dev/md/0 none swap sw 0 0
/dev/md/1 /boot ext3 defaults 0 0
/dev/md/2 / ext4 defaults 0 0
/dev/md3  /ssd  auto   defaults  0 0

Unmount that filesystem and the files should be right where you left them.

First, type sudo umount /ssd, making sure that you are not currently working in that directory, to avoid "Directory in use" errors.

Then move the files in that directory to a safe place.

Finally, remount your filesystem with sudo mount -a.

  • What exactly do you mean by unmount? Should I run something like: sudo umount /dev/md3 ?

  • First, please copy and paste the output of mount (without the -a switch) so I can see exactly what you're talking about.

  • You probably just mounted a filesystem at the same mount point that your files are in. They were likely just obscured when you mounted the filesystem with mount -a.

  • Okay, but then what command should I use to get them back? I'm a little afraid of doing something wrong here
