Upgrade PMG from 6 to 7

pmguser · Mar 21, 2022

Hello,

we have finished the upgrade from PMG (6-to-7) like the documentation.

Now on the dashboard (and the cluster view) on both nodes of the (2 node) cluster we get the following error:

Code:

500 Illegal division by zero at /usr/share/perl5/PVE/ProcFSTools.pm line 221

The error looks like an error while reading CPU data.
If we reboot the nodes the data is shown correctly, then the error occurs some minutes later.
The cluster features (like adding domains etc) are allready working as expected.

Hi,
could you share the output of

Code:

lscpu
cat /proc/stat
perl -e 'use POSIX; print POSIX::sysconf(&POSIX::_SC_CLK_TCK)."\n";'

and the output of

Code:

for i in {1..10}; do sleep 0.$i; head -n 1 /proc/stat; done

once the issue appears?

Are there really only 8 numbers after cpu in /proc/stat or was the output cut off? Our code expects 10 so that might be causing issues. Could you also post the ouput of pmgversion -v?

That's not one of the kernels listed below. Could you also post the output of uname -a? Is the mail gateway running as a container?

Hello Fabian,

Code:

 uname -a

Code:

 Linux pmg-servername 5.10.0 #1 SMP Thu Sep 23 18:26:47 MSK 2021 x86_64 GNU/Linux

The PMG is running as a container - correct.

fiona · Apr 22, 2022

Since lscpu mentions "Parallels", how exactly do you run the container? Is the kernel running below the container really a proper Linux kernel (those should have all ten values since version 2.6.33)?

I sent a patch for discussion to the mailing list, but it still would be nice to know why exactly the values are missing.

pmguser · Apr 25, 2022

The kernel running below the Container is using Virtuozzo 7 with Kernel 3.10.0.
On the Hostnode all 10 Digits are reachable. Only in the Container they are missing.
The Patch you have sent to the mailing list is working. Now the error doesn't occurs any more.
