CITGM permission problems on AIX (aix61-ppc64)

[BridgeAR]

This is ongoing for maybe a week or two that CITGM is having permission issues on AIX. I explicitly opted out of running the tests on that as work around but it would be great to fix that.

Example failure from yesterday: https://ci.nodejs.org/view/Node.js-citgm/job/citgm-smoker/2174/nodes=aix61-ppc64/testReport/junit/(root)/citgm/_nearform_bubbleprof/

Fixed ownership issue on all AIX 6.1 boxes.

I think issues involving the ramdisks should be fixed by moving onto the AIX7.1 boxes which dont have them.

@rsam @richardlau what do we need to do to get CITGM running on the 7.1 boxes?

[richardlau]

@AshCripps The two CITGM jobs use VersionSelectorScript.groovy so adding the label for AIX 7.1 would start running the jobs on those boxes where the script allows. There is an additional complication as the jobs have logic in them for AIX to use the ramdisks which we’ll need to guard for AIX 6.1 while we transition.

[AshCripps]

I can see there is a couple of if [ `uname -s` = "AIX" ]; then in the configuration for citgm-smoker.

If I add the 7.1 label we could change those statements to something like if [ `uname -s` = "AIX" && `uname -v` = "6"]; then then we could ensure that the job only tries to use ramdisk on AIX61

(note: im not familar with the syntax in the jenkins job so no idea if that will work)

[richardlau]

I think the label ends up in a $nodes so it might be simpler to check that for the AIX 6.1 case.

[AshCripps]

Is that variable accesible inside the scripts that are run on the machines? if thats the case it would be much simpler to make use of that.

I added this to our todo checklist. A temporary fix for the /ramdisk0 usage in AIX 6.1 might be to just do ln -s /home/iojs /ramdisk0. I did a quick git grep -i aix, and I don't see any relevant refs to AIX, so likely its only the job config which causes the ramdisk to be used. Lets continue this discussion elsewhere.

@targos can we close this if its fixed?

ci: https://ci.nodejs.org/view/Node.js-citgm/job/citgm-smoker/2179 (but won't start until the current citgm completes)

[AshCripps]

ran a v12 ci: https://ci.nodejs.org/view/Node.js-citgm/job/citgm-smoker/2180/
14.x doesn't build on AIX61 any more so it was just skipped in Sam's run but there was no more permission issues.

Closing now as the permission issues is fixed, any work to include AIX71 in CITGM can be done under #2110. Feel free to reopen if the issue reappears.
