Recover data from folder that was target of mount I had a folder `/acme`, that contained data. I found out that I was supposed to have already mounted `/dev/centos/lv_acme` to `/acme`. I did a minimum amount of research on the web, and it appeared that mounting did not erase data. (Though I now assume I misunderstood what I read.) I executed the command mount /dev/centos/lv_acme /acme As I'm sure you've figured by now, `/acme` no longer contains my data. Is there any way of recovering the data that was in `/acme`?

Easy,


umount /acme


Your original `/acme` directory is simply "hidden" under the mount point.

If nothing prevents you to umount the dir, you can umount it, copy the data elsewhere and remount it.
