Too much space occupied by several filesystems
Here is the output of the
df -h command on my recently set up
df -h Filesystem Size Used Avail Use% Mounted on udev 3,9G 0 3,9G 0% /dev tmpfs 790M 9,8M 780M 2% /run /dev/sdb5 213G 75G 128G 38% / tmpfs 3,9G 152M 3,8G 4% /dev/shm tmpfs 5,0M 4,0K 5,0M 1% /run/lock tmpfs 3,9G 0 3,9G 0% /sys/fs/cgroup /dev/sda1 459G 3,9G 432G 1% /mag tmpfs 790M 108K 789M 1% /run/user/1000
/dev/sdb5 is a SSD of 240G and
/dev/sda1 a HDD of 500G.
My questions is what are the following filesystems that eat up so much space and if there is a way to reclaim that space (if it is not critical for the system of course!).
My main problem is that apparently that space has been deprived from the SSD and not the HDD.
