Freeing up space on the disks
-
By using RAM disks?
What packages are you running?
-
@stephenw10 Hmm not sure. Its on a virtual server.
Packages that I use are:
acme
haproxy
openvpn-client-export
PfBlockerNG (Disabled and not in use)
Status_Traffic_Totals
System_Patches
Telegraf -
Hmm, well I would have guessed pfBlocker was most likely but it's disabled.
Are you sure /var is not shown in that output? It wasn't just omitted in the copy/paste?
It doesn't look like you have it running as a ram disk so I expect it to be there.

@stephenw10 I got this when I ran the "du -Pshx /*" command, and can se the /var
8.0K /COPYRIGHT
1.3M /bin

685M /var -
Hmm, yet it doesn't show in
du -h -d1 /?Is it mounted separately somehow?
What doesmount -pshow? -
@stephenw10 This is the output I get:
/dev/ufsid/5edf741a475fe581 / ufs rw,noatime 1 1
devfs /dev devfs rw 0 0
tmpfs /var/run tmpfs rw 0 0
tmpfs /var/run tmpfs rw 0 0
devfs /var/dhcpd/dev devfs rw 0 0 -
Hmm, what about
df -a? -
@stephenw10 When using the df -a command I get:
Filesystem 512-blocks Used Avail Capacity Mounted on /dev/ufsid/5edf741a475fe581 38557496 27083392 8389512 76% / devfs 2 2 0 100% /dev tmpfs 8192 2488 5704 30% /var/run tmpfs 8192 2920 5272 36% /var/run devfs 2 2 0 100% /var/dhcpd/dev -
Hmm, then why doesn't it show in
du -h -d1 /
I'll still bet it's in /var try:
du -h -d1 /var -
@stephenw10 When I run the "du -h -d1 /var" command I get this:
4.0K /var/msgs
1.3M /var/run

Hmm, not there then. So there's ~10GB being used somewhere in that device that just isn't shown mounted filesystem...
Try
gpart listsee if that shows the expected values. -
@stephenw10 Here is the "gpart lis" output

Hmm, is there some huge coredump file directly in the root of / that's somehow not being counted?
-
@stephenw10 hmm could be?
How do I check that or should I just peform a delete_coredump? -
I would just look in it manually:
ls -ls /Coredumps are usually in /root though so check there too:
ls -ls /root -
@stephenw10 ls -ls / gave me this:

-
Yes, but still only 100s of MBs not GBs. You can remove those core files though.
-
@stephenw10 Weird. I don't understand where 10GB would lie undetected.
How do I remove .core from root?
-
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
