Hi,

Unfortunately, it also crashes on CentOS 7.1.

cat /etc/centos-release

CentOS Linux release 7.1.1503 (Core)

getenforce

Disabled

Mounting, reading & writing operations do work as expected (so far). My guess is that there's some kind of bug with the drv_cfg tool when installed on bare metal (as it works when the OS is virtualized).

Any ideas?

semprunl,

I just tested this on an (admittedly different, but similar) virtual machine at both 7.1.1503 as well as 7.2.1511.

I am unable to get drv_cfg to error in this way, which jives with your experience of "if virtualized, no issue".

Do you have successful volume access otherwise? Is it only --query_guid that it crashes on, or any drv_cfg command?

Did you check the md5sum of the RHEL7 installer archive or re-download and extract on other boxes, md5summing there to verify it's not just a faulty copy of the SDC binary?

Since it works virtualized I'd investigate the difference in driver modules running between bare metal and virtual installs, and test with/without them.

The fact that you need to compile the ethernet driver also doesn't comfort me, and I wonder if the kernel is 100% happy with the NIC.

A non-answer, I know, but let me know what you find.

Hi Rush,

I do have successful volume access but the following drv_cfg commands are crashing the kernel:

--query_diag_counters

--query_guid

The md5sum is valid and the compiled driver is the most current release of the ixgbe driver for Linux, which supports kernel versions 2.6.18 up through 4.3.3.  It also has been tested on the following distributions:

  - RHEL 6.7

  - RHEL 7.2

  - SLES 11SP4

  - SLES 12PS1

I also tried with an older version of ixgbe (4.1.2) which was tested with RHEL 7.1 but still the same outcome (kernel crash).

Thanks for taking a look.

You may find useful the fact that I can not reproduce the crash on CentOS 6.7 using the same server and with the same Ethernet driver.

Hi Semprunl,

Could you solve the problem? I also got a kernel panic with Centos 7.2 and ScaleIO 1.32.3, 1.32.4, 2.0. All panics are related to the sdc. I could reproduce the panic with 3 machines. All running Centos bare metal. I'm testing on 3 Intel NUCs

Hi Tomer,

We will try to reproduce it in the lab and escalate to L3 if necessary.

Thank you,

Pawel

I am running into this issue without having to follow as many of the steps.

I've tried this on 2 systems, one Broadwell-based XeonD 1541 and one Skylake-based 6700k.

I've tested CentOS 7.2 & Ubuntu 14.04 with the 5014 sdc and the 6035 sdc. The result is the same for both.

My steps to reproduce (for CentOS):

install CentOS 7.2

yum update -y

reboot

yum install -y numactl libaio

rpm -U ScaleIO-sdc-2.0-6035.0.el7.x86_64.rpm

during the install, the scini driver attempts to start and this leads to a kernel panic.

because of the above details, I even forcefully disabled / unloaded both the ixgbe and igb network devices (only network devices on my system) and had the same result (kernel panic)

i will try with centos 6.7 next. i also tried with a virtual machine on top and had no issues.

I tested CentOS 6.x as @semprunl did and the sdc packaged installed without issues. I also mounted a volume, formatted it, and wrote to / read from it without any issues.

Hi, was anyone able to solve kernel crash problem ? We ran into the same issue. And we found out, that crash is related to Intel Xeon E5 v4 CPU ( on v3 SDC works fine).

Thanks,

Matas

HI, and seems we found the solution:   SDC version: EMC-ScaleIO-sdc-2.0-7120.0.el7.x86_64.rpm  doesn't crash kernel.

Our setup: CentOS 3.10.0-327.36.1.el7.x86_64

Host bridge: Intel Corporation Xeon E7 v4/Xeon E5 v4/Xeon E3 v4/Xeon D DMI2 (rev 01)

Ethernet controller: Intel Corporation 82599ES 10-Gigabit SFI/SFP+
