tbarrongouthamr: did you say that you have an example where concurrency=2 and the lvm job passes?18:46
gouthamrtbarron: yah, i celebrated early - https://zuul.opendev.org/t/openstack/build/dd7224d59eac45dab4396ad50be6da14 ran on vexxhost18:47
tbarrongouthamr: ah, so we need to re-run with concurrency=1 on rax (run till it lands on rax) and18:49
tbarroncollect the system journal at the end of the job18:49
*** ChanServ sets mode: +o gouthamr18:49
*** ChanServ sets mode: -o gouthamr18:50
tbarrongouthamr: if that doesn't tell us anything we can ask the opendev guys to freeze a node for us18:50
gouthamrtbarron: we have the syslog, what other file would we need?18:52
tbarrongouthamr: it doesn't tell me anything, I was expecting journactl would.18:53
tbarrongouthamr: or do you see something in syslog?18:53
gouthamrtbarron: i see the reboot there too https://zuul.opendev.org/t/openstack/build/3eb91c71fa3041e98b081b9ef00a8419/log/controller/logs/syslog.txt#891518:54
gouthamrthat's all though,18:55
tbarronlike i said18:55
tbarronI don't *know* that the journal will tell us more but it's more modern and tightly integrated with systemd18:59
*** maaritamm has joined #openstack-manila19:05
gouthamrtbarron: hmmm, this is how syslog is being built: https://opendev.org/openstack/devstack/src/branch/master/roles/export-devstack-journal/tasks/main.yaml#L20-L3219:09
tbarrongouthamr: "with just the kernel and sudo messages"19:10
gouthamrtbarron: hold on, the step below extracts the whole journal19:10
gouthamrtbarron: https://opendev.org/openstack/devstack/src/branch/master/roles/export-devstack-journal/tasks/main.yaml#L34-L4819:10

gouthamrwhile i check the journal, lets set the concurrency=1 ^19:17

gouthamrhmm, i don't understand why that happens19:45
gouthamrthere's a marker file created to identify when to start processing logs - they are using the same marker file to grab the system journal to compile a syslog, as well as this export19:46
gouthamroh wait, i'm tying in the wrong channel - context, tbarron and i are debugging the system journal, and the journal entries are from after the reboot19:47
tbarrongouthamr: this is the right channel :D19:47
gouthamrtbarron: yeah, but i took it elsewhere unwisely19:48
tbarrongouthamr: right, same marker file and syslog has the context but not the detail and journalctl is missing the full context19:48
gouthamrtbarron: anywho, i wonder if --no-pager makes a difference there19:48
gouthamrtbarron: the current execution is on inap-mtl01, not a rax - so i bet this thing will pass19:51

gouthamr^ second line's a run which passed20:00
gouthamrlvm2 package versions match as well,  2.02.176-4.1ubuntu3.18.04.320:02
tbarronvexxhost has 80GB root partition; rax has 40GB,  Check zuul-info/host-info.controller.yaml20:06
tbarronmaybe, my eyes are blurry20:06
*** carloss has joined #openstack-manila20:06
tbarronbut my blurry mind is thinking about the BACKING_FILE at 32000M20:07
tbarronDATA_DIR is probably somewhere on the root partition20:08

gouthamrhmmm, looks like that's been the case for a while, tbarron: https://zuul.opendev.org/t/openstack/build/d4f6e4fc780f4fefa09f46acbad8c330/log/controller/logs/df.txt - comes from a ubuntu-bionic-rax-iad node that ran a passing manila-tempest-plugin job on 2020-06-1320:39
gouthamrsimilarly, here: https://zuul.opendev.org/t/openstack/build/6323250bae8c41ccaecb49ddc71e2021/log/controller/logs/df.txt - a ubuntu-bionic-rax-dfw node on 2020-06-1220:39
tbarrongouthamr: yeah, so it's a difference and we *could* be running out of space on root on rax so it reboots but20:42
*** maaritamm has joined #openstack-manila20:42
tbarronthat's just spectulative at this point and it wouldn't explain what has put us over the threshold now and not earlier20:42
tbarronspeculative20:43
gouthamryeah... we can try bumping that down in a different patch20:46
