My root drive has a 143.9 GB of space. I have a vbox vdi that 60GB and the operating system, which should be another 30 GB... leaving me 54GB of free space.
Problem:
This morning I randomly got a "disk space full" error message for my root drive.
I immediately deleted a few gigs of old logs... but than that space eaten (not freed) and I still get the error...
I am unable to locate to 54GB of disk space.
This is: root@machine:/# lsblk
