ScaleIO version 2.0.0.1 OS crash ( reboot ) bug at IM installation

Hi,

It sounds like a bug we encountered with "drv_cfg" (which is part of the SDC installation) - can you please try to go for 2.0.0.2 or use the workaround provided in the KB article (installing 2.0.0.2 is more recommended):

?

Many thanks,

Hi Pawel,

We are currently evaluating ScaleIO, I found some bugs in the version v2.0.0.1 so I'm waiting the release of free version v2.0.0.2 to continue our evaluation session. On the download page I can only see the version v2.0.0.1 available, the v2.0.0.2 you are referring to is still unavailable.

Since you are talking about the version 2.0.0.2 I'd like to know if I can get that version somewhere.

Thanks in Advance,

Davide

Hi Pawel,

Thank you for your reply.

I tried the workaround on the version 2.0.0.1 written in the link you gave me.

Since there seems no free version 2.0.0.2 available.

https://support.emc.com/kb/486909

But it didn't solve the bug. OSs still keep crashing at SDC installation.

I tried the followings

1, added the following parameter to /etc/sysctl.conf

       kernel.panic_on_oops=0

    ran "sysctl -p" to load above setting.

2, rebooted after 1, and repeated 1 again

If there were no workaround for sure now, I would have to try an older version.

Many thanks,

Taizo

OK, thank you for the information - to be honest I didn't know that 2.0.0.2 is not publicly available yet - can you please try again on Monday and see if you can download it?

Cheers,

Pawel

Hello Taiz

I have a few questions:-

1. Which all packages finish installing when the OS crashes?

2. Can you please run the command "rpm -qa | grep -i emc" and let us know which packages got installed on your node?

3. Does the install of SDC finish or does the OS panics/Crash even before the SDC install finishes?

4. Is the issue occurring only on this particular host or does it also occur on other hosts as well?

5. What is the model of the server/vendor you are using. Can you please verify that the hardware compatible with the Kernel version of your OS?

Hi Pawel

We talked to EMC, and got a FTP download link to the Version 2.0.0.2.

So we're now trying to install the 2.0.0.2 but got into a different problem.

Please check the post a teammate of mine put.

Hi SanjeevMalhotra

I will answer to your questions.

1, 2

Only MDM and SDC are installed (I ran a command "yum list installed | grep EMC").

On IM the status stops at MDMs completed, SDCs runnning due to the disconnection by the OS panic.

3

So it is fair to say that the OS panic occurs right after SDC installation.

4

It occurs on all the 3 hosts in the ScaleIO system. The 3 hosts have a SDC.

5

The server model is NEC Express5800 R120g-1M

To be more presices about the OS panic after I changed the sysctl.conf(kernel.panic_on_oops=0).

The srevers stoped rebooting automatically but they just froze and never to come back even after HW rebooting. So We need to do OS re-installations.

Many thanks

The F&F download link has been updated with the 2.0.0.2 version. The website will be updated shortly to reflect that change on the website.

Hi,

I had the same issue with 2.0.0.1 and Centos 7.2. Fixed only with newer kernel from ML repo.

Hi

We now use the 2.0.0.2 version and the installation is successful.

Thank you for the quick response.
