I believe I have found a problem with Linux Mint. (Version 17? - How do I check this?)
I have a program which has been running for several days and has produced an output file several hundred gigabytes in size.
I was about to run out of space (had about 10 GB left) so I stopped the program with CTRL-Z
at a point where the output file was still open but I could ensure no read/write operations were being made at the point when the program was stopped.
Then I deleted the file. (Couldn't open it to clear contents, it was too large!)
Then I recreated the file. (Perhaps it's not a surprise that this caused me problems, I could hardly expect this to work correctly.)
BUT I have 2 problems. Firstly the program doesn't seem to be writing to ANY of the output files anymore? (There are 3 separate ones, only one was deleted.)
Secondly, there is NO EXTRA FREE SPACE? I can't understand why this is? There should be an extra 100 GB ... but there isn't?
Why is this and can I "fix it"? (I don't want my system to be suck forever with a 100 GB hole in it.)
