Disk Usage and Maintenance

We have a pair of PMG servers (Mail Gateway 5.2-7) in a clustered configuration and I've noticed over time in the disk utilization on the second node has been steadily increasing.

The culprit seems to be the following directory.

/var/spool/pmg/cluster

du -hs *
11G 1
11G 2

The usage appears to be a bunch of email files stored in the directories /var/spool/pmg/cluster/{1|2}/{spam|virus} etc.

My question is, is this normal for them to grow so large and is there a manual maintenance routine necessary to prune these emails on a periodic basis?


Best regards,
Eric
 
Those are the mails you have in quarantine - they should get cleaned eventually after the quarantine lifetime on them expires.

What's your setting for your quarantine lifetime?
 
If I click on Spam Detector/Virus Detector -> Quarantine -> Lifetime = 7 Days

find /var/spool/pmg/cluster -type f -mtime +7 |wc -l
1309039

It seems the clean up process is not working. Is there something I can do to manual force the cleanup process?

Best regards,
Eric
 
have you disabled the 'pmgspamreport.timer' on the system (this runs daily and one of the tasks is to run: `/usr/bin/pmgqm purge`

I hope this helps!

No, we have not disabled this to my knowledge. Where would I check to see that it is enabled?

/usr/bin/pmgqm purge
purging database
removed 1313429 spam quarantine files
removed 146 virus quarantine files
removed: /var/spool/pmg/cluster/2/spam/96/2404915DA9FA3724796
removed: /var/spool/pmg/cluster/2/spam/8B/26F9F75D8BDC8FCCE8B

Sorry to follow up to my post....it looks like the service is active?

systemctl status pmgspamreport.timer
● pmgspamreport.timer - Send Daily Spam Report Mails
Loaded: loaded (/lib/systemd/system/pmgspamreport.timer; enabled; vendor preset: enabled)
Active: active (waiting) since Fri 2019-10-18 13:52:25 EDT; 3 months 20 days ago
 
hmm - please post the output of:
Code: 
systemctl list-timers
systemctl cat pmgspamreport.timer
systemctl cat pmgspamreport.service
and check your journal for invocations of the timer/service

another question would be - did you get any spamreports in the past few months?

I assume the purge helped in reducing the diskusage?
 
Stoiko,

To answer your questions in reverse order. Yes, the manually running of the command fixed the disk usage issue.

We had been receiving spam reports, but it appears they were only coming from the other node in cluster not this one. I assume we should we receive notifications directly from both servers?

Here are the output of the commands. Let me know if those look ok at this point or not?

Code:

I am still having to manually run the purge command as it is not automatically cleaning the spam and virus quarantine. I i am running the latest Mail Gateway 5.2-7.

Any thoughts on how to fix this?
 
Hmm - could you:
* run `pmgspamreport.service` once and post the resulting log-lines:
`systemctl start pmgspamreport.service`
* run: `/usr/bin/pmgqm send --timespan yesterday ; echo $?`

maybe it's an issue with the service-file - maybe it's something on your installation...

Thanks!
 
Here are the results...

systemctl start pmgspamreport.service
Job for pmgspamreport.service failed because the control process exited with error code.
See "systemctl status pmgspamreport.service" and "journalctl -xe" for details.
root@mx2:~# journalctl -xe

/usr/bin/pmgqm send --timespan yesterday ; echo $?

Thanks - I need to dig into the source again - since I'd assume that more people would have gotten that problem until now.

do all of your pmg-nodes have the same amount of diskspace?

is the cluster healthy? (pmgcm status)
 
Yes, both nodes are the same size. Note that the disk shown on the command below is because I manually ran the purge again today. It was at approximate 19% on mx2 before doing that.

pmgcm status
NAME(CID)--------------IPADDRESS----ROLE-STATE---------UPTIME---LOAD----MEM---DISK
mx1(1) X.Y.Z.146 master A 4 days 01:35 0.15 33% 11%
mx2(2) X.Y.Z.151 node A 4 days 02:28 0.12 33% 12%
 
Thanks - could I ask you to post some (anonymized) logs from the cluster-synchronization? (pmgmirror/pmgtunnel services)

additionally - are the files only present on mx2? (and only in the directory /var/spool/pmg/cluster/2/spam/) - do the same files exist on mx1 (in the directory /var/spool/pmg/cluster/2/spam/?

Thanks!
 
In regards to the/ var/spool/pmg/cluster/2/spam/ , I looked on mx1 and verified that the same files that are on mx2 DO exist on mx1 so that looks good.

Here are the only logs back from Feb 27 regarding the pmgtunnel services. There is nothing recently regarding that service in the daemon.log files.

In regards to the pmgmirror it looks fairly normal and is regularly posting the below messages to the daemon.log.

This thread is not marked as SOLVED so please let me jump into it.
I'm experiencing the same issue as OP with steadily increasing disk utilization of disk sapce in /var/spool/pmg/spam, but not due to failing pmgspamreport.service.
I have "Send daily admin reports" turned off which disables the pmgspamreport.service.
As a result PMG will never purge old spam from quarantine which is not what I/user expect.
When "Configuration > Spam Detector > Lifetime (days)" is set I did not expect that this depends on enabling sending of daily admin reports. Is there a way to let automatically purge old spam without enabling daily spam reports? I'm on PMG 6.2-5.

* are you running PMG in a cluster or as a single node?

this is not quite right - pmgspamreport.service is used for sending out quarantine reports to the users (and cleaning up the quarantine) - pmgreport.service is used to send out the daily admin reports - both of them are invoked (unless you turn it off manually) by their respective systemd-timers.

this should happen in any case :
Code: 
systemctl cat pmgspamreport.service
# /lib/systemd/system/pmgspamreport.service
[Unit]
Description=Send Daily Spam Report Mails
ConditionPathExists=/usr/bin/pmgqm

[Service]
Type=oneshot
ExecStartPre=-/usr/bin/pmgqm purge
ExecStart=/usr/bin/pmgqm send --timespan yesterday
the /usr/bin/pmgqm purge is responsible for the cleanup.

are you running the latest version? (pmgversion -v)
