*** vhari has joined #openstack-meeting-alt15:07
gouthamrWe're in between two PTG days for manila, hasn't happened a lot in the past15:07
gouthamrso as expected, our meetings are probably going to be light15:08
gouthamrI'm calling your attention to new releases from stable branches: https://releases.openstack.org/teams/manila.html15:08
tbarrongouthamr: ty for doign those!15:09
gouthamrWe released a new minor version of manila off of our Train, Stein, Rocky and Queens branches15:09
gouthamrincludes some API enhancements that are backwards compatible, but address bugs, several other driver bug fixes15:09
gouthamrThe next announcement is that there is no meeting 21 Nov 2019, 15:00 UTC - http://lists.openstack.org/pipermail/openstack-discuss/2019-October/010486.html15:10
gouthamrWhen i sent that email, i forgot that the week after is Thanksgiving Day in the US15:10
gouthamrit's a holiday across the country, and i expect we won't have tbarron, vhari, jgrosso or me for that meeting15:11
gouthamri know we don't have dviroel lseki carloss here atm, but, one of them may want to chair the meeting15:12
gouthamri will reach out to them, and let everyone know via the mailing list and on #openstack-manila if we're going to keep the meeting as is on 28th Nov15:13
gouthamrin terms of where we are in the release schedule, please take a look at15:14
gouthamr#link: https://releases.openstack.org/ussuri/schedule.html15:14
gouthamrthe next major deadline for us is several weeks away15:14
gouthamrhowever, we still target bugs to milestones - helps us keep track of potential backports and plan work in a way15:15
gouthamranyone else got any announcements?15:16
gouthamrokay, moving on...15:16
gouthamr#topic Project Technical Gathering in Shanghai15:16
*** openstack changes topic to "Project Technical Gathering in Shanghai (Meeting topic: manila)"15:16
gouthamrlast week carloss lseki tbarron and vkmc were at the PTG in Shanghai15:17
gouthamrthat happened post the Open Infra Summit, where manila had several presentations and from what i'm told, a well attended Forum session15:18
gouthamri was hoping these guys will be able to give us a short summary of what happened15:18
tbarronHere is our etherpad from the PTG session: https://etherpad.openstack.org/p/shanghai-ptg-manila but I'll add15:18
tbarrona few remarks here15:19
tbarronfor the meeting record :)15:19
lsekio/15:19
gouthamrty tbarron15:19
tbarronlseki!!15:19
tbarronPROS:15:19
tbarronManila events at summit (adopt a share, manila-csi forum, project update) were well attended15:19
tbarronnd got followup questions both in official Q&A and in the hallway, some15:19
tbarronrelated to the actual topics of the sessions, some more general.15:19
tbarron-15:19
* gouthamr marks lseki tardy15:19
tbarronCONS:15:20
tbarronThe rwx storage lightning talk was rescheduled twice and sparsely and randomly attended except by manila people who knew what and when15:20
tbarronThe picture was scheduled for Thursday after several PTG attendees had left.15:20
* tbarron isn't going to mention the box lunches15:20
tbarronPTG:15:20
tbarronWe covered a few topics:15:20
tbarron  retrospective, UI tech debt, OSC completion, CephFS topics15:20
tbarronand touched on active-active15:20
tbarronbut we had new attendees from DKRC and City Network and Inspur so15:20
tbarronemphasis was on "team building".  We all knew that there is going to be a15:20
tbarronvirtual PTG where we can do the harder topics with gouthamr and others15:20
tbarroninvolved :)15:20
tbarron<tbarron-EOF> :)15:20
gouthamrnice, thank you for the summary tbarron15:21
*** dviroel has joined #openstack-meeting-alt15:21
amitoSounds like this was a great summit for Manila :)15:21
gouthamrspeaking of the Virtual PTG, a reminder for folks that we're still polling on dates, here:15:22
gouthamr#link: https://xoyondo.com/dp/qQbsoHtNhi4DCki15:22
tbarronamito: we got quite a bit of coverage and the Adopt a Share presentation made us all proud.15:22
*** skatsaounis_ has quit IRC15:23
tbarronoh, DLRC is a German climate research group15:23
tbarrondon't ask me to actually pronounce their name15:23
tbarron(and we don't really believe in that kind of thing in my country anyways) but they want15:24
jgrosso:)15:24
gouthamrtbarron: "we" don't believe? :)15:24
tbarronto write a Lustre back end driver so if you know others interested in that let me know so I can connect them.15:24
tbarrongouthamr: it's not allowed15:24
gouthamrhahaha15:24
* gouthamr cries a little15:24
gouthamra Lustre backend for manila is most welcome - we've seen some interest/chatter in the scientific-sig over the past months15:25
gouthamrwe'd be happy to help onboard them and land that driver if it's useful for the wider community15:26
tbarrons/DLRC/DKRC/ where 'K' is for Klimat...15:26
gouthamr+1, i see that we also had several prod/pre-prod usecases for manila in the Forum session15:27
gouthamrtbarron: i can add a recap session during the Virtual PTG so we can shed light on some of that15:27
tbarrongouthamr: kk.  The Forum notes failed to mention one use case -- mugsie's home music system requires RWX access from his many devices15:28
*** ayoung has joined #openstack-meeting-alt15:28
gouthamrvery cool15:29
gouthamralright, anything else re: the PTG?15:30
gouthamri'm still waiting on confirmation from a couple of folks with their names on topics15:30
gouthamrto finalize a date15:30
gouthamri should have one by the end of this week15:30
gouthamrand i'll share it with you folks via openstack-discuss@lists.openstack.org15:30
gouthamrlet's move on..15:31
gouthamr#topic Capability Filter enhancement15:31
*** openstack changes topic to "Capability Filter enhancement (Meeting topic: manila)"15:31
gouthamr#link https://review.opendev.org/#/c/688053/ (Make extra_specs value as case-insensitive)15:31
gouthamrI'd like to draw your attention to this change ^15:31
gouthamralthough it is seemingly simple, it's a huge impact on the capabilities scheduler that drives most of our optional API logic15:32
gouthamrit impacts backwords compatibility with existing share types15:33
tbarronin practice or in theory?  In practice are there multiple capabilities that differ only in upper-lower case?15:33
gouthamralthough i do think this is a fine improvement, if we're able to convince ourselves and our users of what pain point it addresses15:33
gouthamrtbarron: in theory15:33
tbarronyeah15:34
amitoI don't really see the point of case-insensitivity here...15:34
gouthamri feel this is a pain point, and i've hated it before, and felt it was okay because we trust the admin doesn't mis-type extra-specs15:34
gouthamrmost people new to manila make that mistake: is it cephfs or CephFS or Cephfs?15:35
* gouthamr cringe: NFS_CIFS or nfs_cifs or Nfs_Cifs15:35
tbarronamito it's easy for operators to not think they have to match case and not know which thing to use15:35
amitoHmm15:36
gouthamri can't think of drawbacks except for clients that need to interact with manila of different versions15:36
amitoJust seems strange to me, it opens a door for strange abominations, e.g. NfS_CiFs, which is equal to nfs_cifs and NFS_CIFS, etc.15:37
tbarronstuff will work in newer versions that doesn't work in old versions (in practice)15:37
amitoIMHO a user should be aware of their input ¯\_(ツ)_/¯15:37
gouthamrin general, yes15:38
gouthamrthe workflow we expect is admins are checking the backend/pool capabilities and setting their extra-specs15:38
tbarronIt would be perverse to actually have two capabilities, NFS and nfs15:38
gouthamrtbarron: +115:38
amitotbarron: true15:39
tbarronBut if we make this change it would be good to have an announcement to openstack-discuss ASAP15:39
tbarronin U15:40
gouthamrlooks like the three of us are in agreement at least.. so let's take a look at that patch15:40
gouthamrack15:40
tbarronthat it will take effect in U15:40
gouthamrand a good reno and docs change explaining the rationale15:40
tbarron+115:40
gouthamrgood stuff.. thanks tbarron amito - Woohyung Han and our friends at TmaxSoft will be happy we're paying attention15:41
gouthamrcool, let's get to the meat of this meeting :D15:42
gouthamr#topic Bugs (jgrosso)15:42
*** openstack changes topic to "Bugs (jgrosso) (Meeting topic: manila)"15:42
jgrossogouthamr thanks15:42
gouthamrheya jgrosso - what do you have for us today? :)15:42
jgrossohttps://bugs.launchpad.net/manila/+bug/180420815:42
openstackLaunchpad bug 1804208 in Manila "scheduler falsely reports share service down" [High,Triaged] - Assigned to Lucio Seki (lseki)15:42
jgrossoJust looking for an update15:42
gouthamrack15:42
jgrossolseki :)15:43
gouthamrlseki's last update was:15:43
gouthamr"It's normal to manila-share service be shown as `down` for a while until re-exporting all the shares."15:43
jgrossoyep15:44
lsekiso15:44
gouthamri thought we're skipping the re-export right now, lseki15:44
gouthamrunless we discover that the backend config/info has changed15:44
lsekiactually Naresh was able to reproduce the issue, in a more heavy loaded env15:45
jgrossois this still HIGH importance?15:46
lsekiand it's in our backlog to investigate and fix it, but the priority is not that high15:46
jgrossook will lower to MED15:46
lsekijgrosso: ok!15:46
gouthamragree, we can bump the importance down, but are you planning to do this during this cycle, lseki15:46
gouthamrit'd be nice to understand why the problem occurs - we did enhance driver resource setup15:47
gouthamr#link: https://review.opendev.org/#/c/457545/ (Change ensure share to make startup faster)15:47
gouthamr#link: https://review.opendev.org/#/c/580777/ (Fix ensure_shares bugs)15:48
gouthamri wonder if we (still) have any bugs in that codepath15:48
lsekigouthamr not sure if we'll be able to work in this cycle...15:49
gouthamrlseki: ack, then we'll probably have to have someone pick this up15:50
gouthamrlseki: do update the bug in case you have any more thoughts/info, we'll talk about this again for sure in the context of active-active during the PTG15:51
jgrossoI dont have to many more bugs for today15:51
jgrossosome people are not here15:51
lsekigouthamr: ack, thanks!15:51
jgrossoI did re visit alot of bugs15:51
gouthamrjgrosso: nice, thank you for doing that :)15:52
gouthamralright then15:52
jgrossoso I have a new triage pad , just to make it easier for me15:52
jgrossohttps://etherpad.openstack.org/p/manila-bug-triage-pad-new15:52

tbarronjgrosso: i'm glad you and gouthamr are organized, we need more of that!15:53
jgrossotbarron thanks !15:54
