Been using Ubuntu for a couple of weeks now and have encountered a problem. I have the message "No space left on device" and after searching for a while I found that /dev/loop0 is taking up huge space. How do I unmount/empty /dev/loop0?
After command: df -h
greger@ubuntu:/$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/loop0 12G 11G 627M 95% /
udev 1.9G 4.0K 1.9G 1% /dev
tmpfs 791M 1000K 790M 1% /run
none 5.0M 0 5.0M 0% /run/lock
none 2.0G 388K 2.0G 1% /run/shm
/dev/sda4 151G 12G 139G 8% /host
Am I right if this command means that a lot of processes is using it?
greger@ubuntu:/$ fuser -m /dev/loop0
/dev/loop0: 1905 1945 1946 1960 1968 1970 1977 1989 1992 1997 2000 2002 2008 2009 2010 2013 2019 2020 2027 2029 2040 2044 2048 2051 2052 2055 2061 2069 2077 2094 2096 2098 2106 2108 2109 2139 2141 2162 2192 2201 2203 2205 2207 2209 2242 2254 2256 2276 2284 2293 2300 2316 2330 2339 2348 2438 2447 2449 2453 2572
What shall I do?
This file: /dev/loop0 is a special type of system file used as a virtual device so it doesn't take up any space and is used to mount image files and ISO files.
As I see, /dev/loop0 is mounted on /, so I assume that this is a Wubi system and in this case something else is using your space.
This command: df -h is for showing you the space left and used on the virtual drive image on the physical drive. You must to use du command to see exactly which files are taking your space.
