1006349 - wrong cmos time for b-2008-sm-0002

Status: RESOLVED WONTFIX

(Infrastructure & Operations :: RelOps: General, task)

Description

[Massimo Gervasini [:massimo]]

b-2008-sm-0002 has a wrong clock setting.

coop: "Every time it reboots, its clock gets set back to UTC. Not sure if it's relevant, but running |w32tm /query /source| tells me the time is coming from the CMOS clock." (https://bugzilla.mozilla.org/show_bug.cgi?id=1005427#c2)

We need the clocks to be set to PDT.  I've give this to aj in hopes that he's seen this issue before on other seamicros and knows a fix.

I logged in to the chassis to take a look at the clock, and it's reporting the correct time AND using ntp:

seamicro-c1# show clock
Wed May  7 05:00:30 PDT 2014
seamicro-c1# show ntp
     remote           refid      st t when poll reach   delay   offset  jitter
==============================================================================
*10.22.0.6       64.246.132.14    2 u  923 1024  377    0.312   -0.421   0.057
+10.22.0.7       72.20.40.62      3 u  626 1024  377    0.999   -0.048   0.266

I don't see anything about separately setting the time on the blades, though there is a note:

"Note: On internal servers, you cannot execute the OS command “hwclock --systohc” to set the current system time to the hardware real time clock (RTC). This is because there is only one physical RTC in the chassis, which resides on the SM card."

As per Amy's troubleshooting, things are correctly configured on the chassis side.
Seems there's a Windows setting that needs to be set/check to make sure that it DOESN'T use the CMOS clock for timing.

If there's a Windows node I could check to troubleshoot (ie reboot when needed etc), please let me know and point me to login (gpg).

After further discussion in irc, I am troubleshooting the issue with node 0 in the chassis.

Comment 5

Test(s) results:
node 0 already has CentOS6.x installed, booting into single user mode and correct time was obtained:
[root@seamicro-test1 /]# date
Mon May 12 09:42:13 PDT 2014

# hwclock 
Mon 12 May 2014 09:43:06 AM PDT  -0.770300 seconds

Having some issues with kickstarting in specific vlans (in order to test a fresh "live" system). Will update again with results.

Going to wontfix this because we're working around it at the OS level.
