Hi I have many files that have been deleted but for some reason the disk space associated with the deleted files is unable to be utilized until I explicitly kill the process for the file taking the disk space
$ lsof /tmp/
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
cron 1623 root 5u REG 0,21 0 395919638 /tmp/tmpfPagTZ4 (deleted)
The disk space taken up by the deleted file above causes problems such as when trying to use the tab key to autocomplete a file path I get the error
bash: cannot create temp file for here-document: No space left on device
But after I run
kill -9 1623 the space for that PID is freed and I no longer get the error.
My questions are:
- why is this space not immediately freed when the file is first deleted?
- what is the best way to get back the file space associated with the deleted files?
and please let me know any incorrect terminology I have used or any other relevant and pertinent info regarding this situation.
