It does reclaim some of the lost space, yes - hence one reason for rebooting, when I run out of space - but there is still a creeping issue of space disappearing in increments of a couple mb at a time.
Well, than you have two different issues at hand. Two deal with a space that is reclaimed by reboot, run (when some space already gone) lsof -nP +L1 and look for anything suspicious here.
All entries are marked as deleted. I could give you the whole list, but it is very long, and besides I am trying not to give out my user name, and other specific details. Anything I ought to look for, if all items are already marked as deleted?
Also, if /tmp is on real disk (not tmpfs), it is also a primal suspect for a space that is reclaimed by reboot.
I did look in /tmp, but there is nothing much there; although the presence of a systemd entry does bother me - but maybe this is by design.
For an issue with a long term lost space, the only thing i cab suggest it to setup a cron to run something like du -xcbd2 / > $(date +%j%H)
Running the cron job now.
