Freeing up space on the disks

[stephenw10]

Hmm, then why doesn't it show in du -h -d1 /

I'll still bet it's in /var try: du -h -d1 /var

[RobinH]

@stephenw10 When I run the "du -h -d1 /var" command I get this:

4.0K /var/msgs
1.3M /var/run
12K /var/audit
4.0K /var/backups
4.0K /var/preserve
4.0K /var/crash
4.0K /var/mail
4.0K /var/heimdal
4.0K /var/account
425M /var/db
241M /var/cache
4.0K /var/yp
32K /var/spool
4.0M /var/tmp
8.0K /var/cron
4.0K /var/rwho
4.0K /var/games
4.0K /var/authpf
3.2M /var/log
64K /var/unbound
12K /var/at
4.0K /var/empty
7.6M /var/etc
4.4M /var/dhcpd
8.0K /var/lib
687M /var

[stephenw10]

Hmm, not there then. So there's ~10GB being used somewhere in that device that just isn't shown mounted filesystem...

Try gpart list see if that shows the expected values.

@stephenw10 Here is the "gpart lis" output

[stephenw10]

Hmm, is there some huge coredump file directly in the root of / that's somehow not being counted?

[RobinH]

@stephenw10 hmm could be?
How do I check that or should I just peform a delete_coredump?

[stephenw10]

I would just look in it manually: ls -ls /

Coredumps are usually in /root though so check there too: ls -ls /root

[RobinH]

@stephenw10 ls -ls / gave me this:

Seems like the .core files are bigger?

[stephenw10]

Yes, but still only 100s of MBs not GBs. You can remove those core files though.

[RobinH]

@stephenw10 Weird. I don't understand where 10GB would lie undetected.

How do I remove .core from root?

[stephenw10]

Indeed, I'm not sure here that space is being used.

You can remove those files from the command line as root or at Diag > Command Prompt like: rm /root/ntopng.core
Obviously be careful doing that!

Steve

[RobinH]

@stephenw10 Got 2% less... (77 to 75%)
Dont really know what to do more then the things you suggested.

There must be something that stores those 10GB's..
