I have file servers which are used to store files. Files might reside there for a week, or for a year. Unfortunately, when I remove files from the server,
df command doesn't reflect the freed up space. So eventually, the server gets filled up (
df shows 99%), and my script doesn't send any more files there, except there might be a few dozen GB of free space on there.
noatime flag on the mounted partitions if that makes any difference.
