748873 - verify that all r4 machines have same amount of ram

Status: RESOLVED FIXED

(Infrastructure & Operations :: DCOps, task, P2)

Description

[Chris AtLee [:catlee]]

in https://bugzilla.mozilla.org/show_bug.cgi?id=733798#c9 peter says that he thinks some of the r4 machines have 16GB of RAM, but the machine I looked at had 8GB. We should verify that all the r4 machines have the same amount.

found in triage.

I found this python script.
We can easily modify it and create a report for all the needed machines.

We can also WONTFIX and open if it really helps.

[Justin Wood (:Callek)]

catlee, is this still needed/wanted
arr, is there a way on your end to verify this for us if it is still wanted

Comment 4

[Amy Rich [:arr] [:arich]]

They should all have 2 4G DIMMs. You can verify by running:

/usr/sbin/system_profiler SPMemoryDataType

Comment 5

[Chris AtLee [:catlee]]

yeah, I think we should still verify they have the same amount of ram.

Comment 6

[[e-mail] (:bhearsum)]

If someone wants to write a script for this, it's easy to check for over ssh:
cltbld@T-W864-IX-014 ~
$ systeminfo | grep "Total Physical"
Total Physical Memory:     8,183 MB

Comment 7

[Chris Cooper [:coop] (he/him)]

Has 1x4GB DIMM (missing 2nd DIMM):
talos-r4-snow-077
talos-r4-snow-082
talos-r4-snow-087

Has 2x1GB DIMMs:
talos-r4-snow-066
talos-r4-snow-079

Has 2x8GB DIMMs:
talos-r4-snow-120

Has different speed DIMMs (1333 MHz instead of 1067 MHz):
talos-r4-snow-013
talos-r4-snow-115
talos-r4-snow-120 (also has 2x8GB DIMMs)
talos-r4-snow-150

Over to DCops to fix this. 

Please ping buildduty to schedule taking these machines offline to standardize the RAM.

Comment 8

[Aki Sasaki (not active)]

All machines in comment 7 are disabled in slavealloc and shut down.

Comment 9

[Salvador Espinoza [:sal]]

We changed and verified DIMMS on the following;
(2x4 1067 MHz)

talos-r4-snow-150 
talos-r4-snow-120  
talos-r4-snow-115 
talos-r4-snow-013 
talos-r4-snow-079
talos-r4-snow-066
talos-r4-snow-087
talos-r4-snow-082
talos-r4-snow-077
