I copied some things to the /data folder on my ubuntu 10.04. After restarting all the data was gone. After some investigation I figured out that automount was using the /data folder (it appeared in lsof | grep /data and /etc/auto.master contains /data entry ), which I completely forgot about. Now, I have two questions:
1) Is there a way to recover my data or has automount deleted it?
2) df -h tells me that my / partition has 1.3 GB free while I am sure it had 3 GB before I copied the stuff to my /data folder, and the "missing" 1.7 GB seems exactly right for the size of my copied stuff. Where would this data be moved to (i.e. this would answer 1) and how do I get my 1.7 GB back?
