kata-irc-bot<graham.whaley> Hi folks. this is a heads up/rfc - I'm intending to add @penny.zheng to the Kata CI (Jenkins) admin team via github permissions. Any acks or nacks, file here or contact me direct etc. :slightly_smiling_face: /cc @salvador.fuentes08:57

brtknrgmmaha: no worries, i'll be producing a flame graph while running fio to pin down why in the case of beegfs, we dont get the same performace as ceph mount09:30

brtknrgmmaha: hmm i dont even seem to be able to run fio for a beegfs mount... ceph seems to be fine14:21
brtknrbut also, it looks like for ceph, things are committed to memory14:21
gwhaleybrtknr: fio has a number of modes for trying to bypass memory caches and things - you may be able to tweak it to force a store out to the actual server etc. but, you might already know this ;-) We have an fio test in the kata repos - it is a little simple, but let me grab a link14:23

brtknrgwhaley: just figured that the fio tests are failing when using libaio engine... works with falloc14:30
brtknrgwhaley: although your default ioengine also appears to be libaio14:31
kata-irc-bot<graham.whaley> this rings a small bell far away in my head.... let me see, did I put a note in that test...14:31
kata-irc-bot<graham.whaley> I have this in the test... possibly relevant: ```#  When running 'direct', the file size should not really matter as nothing should be #  cached. #  If you are running cached (direct=0), then it is likely this whole file will fit in #  the buffercache. You can make this filesize larger than the container RAM size to #  make a cached test mostly miss the cache - but, depending on the runtime and setup, #  you might just end up14:32
kata-irc-bothitting the host side buffercache. You could of course make the #  filesize bigger than the host RAM size... it might take fio some time to create that #  testfile though. FIO_FILESIZE=${FIO_FILESIZE:-1G} FIO_IOENGINE=${FIO_IOENGINE:-libaio} FIO_IODEPTH=${FIO_IODEPTH:-16} ```14:32
kata-irc-bot<graham.whaley> iirc, I hit some issues around file/buffer sizes and libaio - I think you have to get the correct combo. Been a while though, and fio is somewhat compled!14:33
kata-irc-bot<graham.whaley> s/compled/complex/14:33
brtknrgwhaley: I do not have any problems running fio in qemu/9p setup, only hitting issues in the nemu/virtiofs setup14:35
brtknrbut I see in the notes that falloc causes problems with 9p14:35

kata-irc-bot<graham.whaley> OK, it's official, I don't seem to get on or like either of our test frameworks (BATS and ginkgo).... @julio.montes @salvador.fuentes - I'm trying to set ginkgo FOCUS to just run the tests at https://github.com/kata-containers/tests/blob/master/integration/docker/user_test.go#L33 that are under `Describe("users and groups")` - can you clue me in to what FOCUS='regexp' you think I should be setting??? coz, I seem to be failing to16:45
kata-irc-botfind it or find useful examples .... thx!16:45
kata-irc-bot<salvador.fuentes> `FOCUS="users and groups"` should work16:46
kata-irc-bot<graham.whaley> that's what I thought (and am trying). hmm, let me check then - I do get 18 tests run, but, afaict I modified something and they should fail - maybe I have gotten something else missing etc. thx for confirming I'm not completely mad though :slightly_smiling_face:16:47
kata-irc-botAction: graham.whaley switched the postgress image used for that test to busybox, but the 'as user postgress' tests still seem to run. I need to understand what is happening more it seems16:49
