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.
