PVE 4.1 cluster fresh install high cpu load no vm's

[ronsrussell]

Dell C6100, dual six core L5640, 24G RAM
1 x 120G SanDisk SSD
2 x 240G Crucial SSD
4 x 160G Fujitsu SAS 15K

The problem I am seeing is that two of the four nodes present a constant load average of 3.
The other two present load average of 0.
There are NO VM's currently confgured.
The plan is to create a ceph cluster.
As a matter of fact these same servers were previously configured as a four node PVE/Ceph cluster and worked fine. We moved all the VM's to another cluster in order to upgrade this cluster to version 4. Here is pveversion info on the four nodes -

I would really appreciate a reply from one of the PVE gurus regarding this issue.

 

[mir]

Is BIOS and firmware versions identical on all nodes?

 

[spirit]

Do you see something special with "top" ?

 

[ronsrussell]

BIOS & firmware identical on the four nodes that are running on identical hardware.
TOP cmd on nodes 2 & 3 shows process kipmi0 using 100% CPU.
I see that kipmi0 is running on nodes 1 & 4 also but using virtually no CPU.

 

[spirit]

do you have installed openmanage ?
Also, if you reboot the node, does the problem disappear.
kipmi0 process is the ipmi kernel module, so it could be dell omsa polling sensors at a too much high rate.

 

[ronsrussell]

All four of these nodes were running PVE 3 for over a year with no problems.
I moved all VM's to another cluster in order to "upgrade by doing fresh install" to version 4.
After wiping all drives, I completed fresh installs of PVE4. Then I completed the ceph install. Nothing else has been installed.
Nodes have been rebooted numerous times.
Using "ps aux" command I see kipmi0 running on all four nodes but only on nodes 2 & 4 is it running at 99-100% CPU.
See screen shot showing side by side node 1 & 2 running top.

Does one of the following pages give a solution to your problem?

[ronsrussell]

The only relief I have found is from running this command which I discovered in another posting -
"echo 1 > /sys/module/ipmi_si/parameters/kipmid_max_busy_us" which reduces kipmi0 CPU utilization to below 1%.
