I was zeroing out the free space on my Ubuntu 12.04 using
sfill, when the command stopped responding and I had to reboot the machine.
Now, the system says that it has no space left, and that it is running in low graphics mode. Before this happened, I had nearly 500 gig free.
df says there are 0 bytes free.
df -i reports only 2% of INODES used.
fsck and it didn't resolve the issue.
What can I do to resolve the issue?
