DC Temperatures..

Oh, I see.

Hey OVH, can we get RBX-4 moved to the north pole? It would greatly benefit the server temperatures :-D.

Nah, but in all seriousness that explains a fair bit. Though, I see they need more stairs.

@rickyday Being silly is fine, that's why I jokingly responded what I did :-) - You have to have a sense of humour in this line of work, or stress will get to you.

RBX4 has a different cooling system, and is designed to take advantage of outdoor air(flow) in addition to its water cooling.

As my reply was a bit silly I will try and add something helpful

My two servers are in RBX 3 and no problems to report.

Server mentioned in OP is in RBX-4.

The other server is in RBX-1 (also an SP) however it's temperatures appear to be fine.

If they have replaced the motherboard twice, it may not be the motherboard causing the crashing, have they checked RAM?

Are you kidding? I'm a Linux-user, and a computer geek, I've worked hard to grow a long beard and long hair, get pale white skin, have a good basement and spend as little time outside as possible.

Yeah, but I'll be keeping a closer eye on those drives now . It's strange because in the other server, they do not have the up/down heat issue and seem to be relatively stable temperature wise.

Hey guys,

Just wondering, anyone else here noticing odd temperatures on your servers? I've noticed mine were going up and down all night.

Just going through logs and found these:

Jul 31 11:40:51 web smartd[2885]: Device: /dev/sda [SAT], SMART Usage Attribute: 190 Airflow_Temperature_Cel changed from 68 to 67
Jul 31 11:40:51 web smartd[2885]: Device: /dev/sda [SAT], SMART Usage Attribute: 194 Temperature_Celsius changed from 32 to 33
Jul 31 11:40:52 web smartd[2885]: Device: /dev/sdb [SAT], SMART Usage Attribute: 190 Airflow_Temperature_Cel changed from 66 to 65
Jul 31 11:40:52 web smartd[2885]: Device: /dev/sdb [SAT], SMART Usage Attribute: 194 Temperature_Celsius changed from 34 to 35

Looks good there? Yup.

However, few hours later:

Jul 31 21:40:51 web smartd[2885]: Device: /dev/sda [SAT], SMART Usage Attribute: 190 Airflow_Temperature_Cel changed from 63 to 62
Jul 31 21:40:51 web smartd[2885]: Device: /dev/sda [SAT], SMART Usage Attribute: 194 Temperature_Celsius changed from 37 to 38
Jul 31 21:40:51 web smartd[2885]: Device: /dev/sdb [SAT], SMART Usage Attribute: 190 Airflow_Temperature_Cel changed from 62 to 61
Jul 31 21:40:51 web smartd[2885]: Device: /dev/sdb [SAT], SMART Usage Attribute: 194 Temperature_Celsius changed from 38 to 39
A little high.. max drive temperature reported by SMARTD is max of 41C recommended.. That's pretty close to the limit.

But then...

Aug 1 00:10:51 web smartd[2885]: Device: /dev/sda [SAT], SMART Usage Attribute: 190 Airflow_Temperature_Cel changed from 63 to 62
Aug 1 00:10:51 web smartd[2885]: Device: /dev/sda [SAT], SMART Usage Attribute: 194 Temperature_Celsius changed from 37 to 38
Aug 1 00:10:51 web smartd[2885]: Device: /dev/sdb [SAT], SMART Usage Attribute: 190 Airflow_Temperature_Cel changed from 61 to 60
Aug 1 00:10:51 web smartd[2885]: Device: /dev/sdb [SAT], SMART Usage Attribute: 194 Temperature_Celsius changed from 39 to 40
That's even closer to the limit...

And then, a sudden drop:

Aug 1 05:10:51 web smartd[2885]: Device: /dev/sda [SAT], SMART Usage Attribute: 190 Airflow_Temperature_Cel changed from 63 to 68
Aug 1 05:10:51 web smartd[2885]: Device: /dev/sda [SAT], SMART Usage Attribute: 194 Temperature_Celsius changed from 37 to 32
Aug 1 05:10:51 web smartd[2885]: Device: /dev/sdb [SAT], 8 Currently unreadable (pending) sectors
Aug 1 05:10:51 web smartd[2885]: Device: /dev/sdb [SAT], 8 Offline uncorrectable sectors
Aug 1 05:10:51 web smartd[2885]: Device: /dev/sdb [SAT], SMART Usage Attribute: 190 Airflow_Temperature_Cel changed from 60 to 66
Aug 1 05:10:51 web smartd[2885]: Device: /dev/sdb [SAT], SMART Usage Attribute: 194 Temperature_Celsius changed from 40 to 34
Aug 1 05:40:51 web smartd[2885]: Device: /dev/sda [SAT], SMART Usage Attribute: 190 Airflow_Temperature_Cel changed from 68 to 69
Aug 1 05:40:51 web smartd[2885]: Device: /dev/sda [SAT], SMART Usage Attribute: 194 Temperature_Celsius changed from 32 to 31
Aug 1 05:40:51 web smartd[2885]: Device: /dev/sdb [SAT], 8 Currently unreadable (pending) sectors
Aug 1 05:40:51 web smartd[2885]: Device: /dev/sdb [SAT], 8 Offline uncorrectable sectors
Aug 1 05:40:51 web smartd[2885]: Device: /dev/sdb [SAT], SMART Usage Attribute: 190 Airflow_Temperature_Cel changed from 66 to 68
Aug 1 05:40:51 web smartd[2885]: Device: /dev/sdb [SAT], SMART Usage Attribute: 194 Temperature_Celsius changed from 34 to 32
And currently:

Aug 1 10:10:51 web smartd[2885]: Device: /dev/sda [SAT], SMART Usage Attribute: 190 Airflow_Temperature_Cel changed from 63 to 64
Aug 1 10:10:51 web smartd[2885]: Device: /dev/sda [SAT], SMART Usage Attribute: 194 Temperature_Celsius changed from 37 to 36
Aug 1 10:10:51 web smartd[2885]: Device: /dev/sdb [SAT], 8 Currently unreadable (pending) sectors
Aug 1 10:10:51 web smartd[2885]: Device: /dev/sdb [SAT], 8 Offline uncorrectable sectors
Aug 1 10:10:51 web smartd[2885]: Device: /dev/sdb [SAT], SMART Usage Attribute: 190 Airflow_Temperature_Cel changed from 62 to 63
Aug 1 10:10:51 web smartd[2885]: Device: /dev/sdb [SAT], SMART Usage Attribute: 194 Temperature_Celsius changed from 38 to 37
So yeah, temperatures seem to be all over the place.

Anyone else noticing this? The server in question is in low I/O load right now.
