Littering in /tmp on R82 MDS

[Hugo_vd_Kooij]

We found some Littering on R82 MDS machines.

It seems the /tmp directory is used but not cleaned up properly.

You can find the stuff with the following command:

find /tmp -name 'bladesStatus*' -exec ls -ld {} \;

And if neded you can cleanup with:

find /tmp -mtime +30 -name 'bladesStatus*' -exec rm -r {} \;

Which only leaves you with the last 30 days of this stuff.

But it would be nice if a system is a bit more tidier and cleans up after itself.

Is seems like something runs at a 6 hours interval but failed to cleanup this bit.

Anyone else seen this?

Is there possibly a cron job there there?

[Hugo_vd_Kooij]

We use plenty of crontab jobs. But none of them every 6 hours. ... But the default update check is every 6 hours .... So that might be where this happens.

Did anyone see it on normal SmartCenters? I don't have access to one at the moment that runs R82.

I just checked and my R82.10 MDS doesn't create them.

[Expert@MDS01:0]# find /tmp -name 'bladesStatus*' -exec ls -ld {} \;
drwxr-xr-x 2 admin config 47 Feb 16 17:24 /tmp/bladesStatus
[Expert@MDS01:0]#

From my R82 lab:

[Expert@CP-MANAGEMENT:0]# find /tmp -name 'bladesStatus*' -exec ls -ld {} \;
drwxr-xr-x 2 admin config 100 Apr 20 2025 /tmp/bladesStatus
[Expert@CP-MANAGEMENT:0]#

I have R82 lab mgmt, never seen that issue.

The odd thing is we got a incident from a customer about the root partition filling up.  That's when I started to investigate our R82 MDS farm. And it happens on all of them. Not on R81.20 neither on R82.10 and I guess it didn't happen on older versions as well.

I'll see if I can update with a `screenshot` of it. And there is now a TAC case for it.

[the_rock]

Sounds good, keep us posted!

[Hugo_vd_Kooij]

Oh. I spotted this also on on our last R81.20 MDS machines as well. They are rapidly going extinct as we upgrade them to R82.

TAC is investigating.

Interesting point. On my R82.10, I can't see any 'bladeStatus*' directories, but on our production MDS, I can see more than 400 of them, each consuming 8 KB.
I will check if we want to implement a cron job for that. Thanks for notifying.

We did not impement a cron but asked our designated diamond service engineer to take care about it.
