[12:03:30] mbarbosa joins the room
[16:49:45] meffie joins the room
[16:55:27] <kaduk@jabber.openafs.org/barnowl> No real snow (accumulation) here yet, just rain today
[16:56:49] <meffie> rain here too.
[17:00:15] wiesand joins the room
[17:00:40] <wiesand> here too
[17:01:29] <wiesand> reseeded the lawn in november - and now it's about time i mow it (!)
[17:01:57] <meffie> in january? wow.
[17:02:27] <kaduk@jabber.openafs.org/barnowl> I think I should be mowing the back pretty soon, too -- there's one
patch that grows faster than everything else, and I only have a reel
mower so I can't let it get too tall
[17:02:45] <wiesand> well the climate here is moving towards "tropical" rapidly
[17:03:16] <wiesand> all those "garden calendars" are completely obsolete
[17:03:59] <wiesand> a reel mower is one w/o motor?
[17:04:22] <kaduk@jabber.openafs.org/barnowl> right
[17:04:47] mvita joins the room
[17:04:53] <wiesand> that's what I'm using too - it's quiet and good for me ;-)
[17:05:07] <kaduk@jabber.openafs.org/barnowl> It has a "reel" of paddles that's geared to rotate quickly and push
the blades of grass against a straight blade, if I understand the
etymology correctly.
[17:05:12] <mvita> sorry, tech woes w/ my jabber client
[17:05:38] <meffie> that's a good workout.
[17:05:39] <kaduk@jabber.openafs.org/barnowl> mvita: I started the conversation to check if I was having tech woes,
so you're in good company
[17:05:40] <wiesand> ben, I guess we're using the same kind of device
[17:05:48] <kaduk@jabber.openafs.org/barnowl> sounds like it, yes
[17:06:10] <mvita> we have a reel mower as well but only use it for small tasks
[17:06:19] <mvita> the yard is too big to use it for everything
[17:06:23] <meffie> i grew up with one of those mowers. i never want to see one again.
[17:06:27] <kaduk@jabber.openafs.org/barnowl> (e.g.,
https://www.amazon.com/American-Lawn-Mower-Company-1815-18/dp/B00004R9UK/)
[17:06:34] <wiesand> heh
[17:07:07] <wiesand> ben: yes, that's the kind
[17:07:39] <kaduk@jabber.openafs.org/barnowl> Anyways, I suppose we should probably get started
[17:07:41] <meffie> that one doent have the wooden handles full of splinters!
[17:08:04] <meffie> you young ones have it so good these day.
[17:08:05] <wiesand> mike: no, those really belong into your bad memories
[17:08:05] <meffie> s
[17:08:06] <kaduk@jabber.openafs.org/barnowl> meffie: it's probably better lubricated and adjusted, too :)
[17:08:30] <mvita> ours is an antique, like this:  https://i.ytimg.com/vi/Nex8YnFpBB8/maxresdefault.jpg
[17:08:57] <wiesand> ah well I understand your contemption
[17:10:15] <meffie> that's the one i used, but duller and more rust :)
[17:10:39] <meffie> (i mean ours was rustier )
[17:10:45] <kaduk@jabber.openafs.org/barnowl> how many passes did you have to make over the same patch to get all
the grass cut?
[17:11:17] <meffie> it took all day, eventually we got a gas mower
[17:11:38] <kaduk@jabber.openafs.org/barnowl> all day, yikes.  'cause in summer you have to do it like every 2-3
days!
[17:11:39] <wiesand> it's a viable technology though - cheap, quiet, healthy, no cable, no fire risk, no CO2 emissions, can use it sunday morning in good conscience…
[17:12:27] <meffie> i suppose new ones are lighter and work better.
[17:12:52] <wiesand> right ;-)
[17:12:57] <kaduk@jabber.openafs.org/barnowl> Only somewhat lighter, I think, though my memories of the "antique"
ones are pretty faded at this point
[17:13:47] meffie has set the subject to: antique lawn mowers
[17:14:08] <mvita> heh
[17:14:25] meffie has set the subject to: openafs 1.6.25
[17:14:26] <mvita> the meeting minutes will be enthralling
[17:14:36] <wiesand> I inherited an electric, cable bound mower with my house. Used it twice, then got a reel mower (admittedly, the best one I could get).
[17:14:55] <wiesand> Never used that electric thing again.
[17:15:10] <wiesand> Anyway, yes, we should probably get on topic ;-)
[17:15:18] <kaduk@jabber.openafs.org/barnowl> electric mowers have made gains in leaps and bounds in recent years,
as I understand it
[17:15:24] <kaduk@jabber.openafs.org/barnowl> sorry; I'll stop now
[17:15:52] <wiesand> It's alright ;-)
[17:16:03] <meffie> :)
[17:16:23] <wiesand> mike: I sense some urgency regarding a 1.6.25 - how come?
[17:17:16] <meffie> i just get questions from sites wanting to know if a release is planned. and some asking about gerrit 14018
[17:18:35] <meffie> is there anything i can do to help with the 1.6.25 release?
[17:18:41] <wiesand> there actually are sites using "read only fileservers"?
[17:18:50] <meffie> yes
[17:19:05] <wiesand> ok…
[17:19:10] <kaduk@jabber.openafs.org/barnowl> Sites that use AFS for software distribution, for example
[17:19:29] <meffie> yes, exactly.
[17:19:38] <wiesand> I thought we have read-only volumes for those use cases...
[17:20:03] <meffie> and to scale out, it is distributed to cells with ro fileservers
[17:20:26] <meffie> rw is only used to stage new releases.
[17:20:32] <mvita> yes, this is a scaling strategy to work around the site limit for a given volume per cell
[17:21:27] <meffie> (and help partition problems)
[17:21:28] <wiesand> ok… anyway, that fix would enter 1.8.x first - why is it that urgent for the old stable series?
[17:21:53] <kaduk@jabber.openafs.org/barnowl> good question :)
[17:21:54] <mvita> there are also sometimes regulatory  / compliance reasons why you want to forbid RW as much as technically possible
[17:22:07] <meffie> not super urgent, but i recommend we should try to include that fix.
[17:22:36] <wiesand> my personal priority is still 1.8.x
[17:22:46] <meffie> ah, ok.
[17:22:47] <wiesand> probably followed by 1.9
[17:22:52] <wiesand> then 1.6.x
[17:23:23] <kaduk@jabber.openafs.org/barnowl> I note that we got a question on -info about a 1.6.x fileserver that
got volume id corruption when the partition was more than 95% full
(even though it still had 3TB absolute space left).
[17:23:31] <meffie> oh, thanks for clarifying. i had it backward!
[17:23:47] <wiesand> and re helping that along: just slow down the earth's rotational speed to get me a few additional hours per day
[17:24:03] <kaduk@jabber.openafs.org/barnowl> I assume that we mostly just want them to try 1.8.x, though I didn't
find any commits to src/viced that seemed likely to be directly
affected by physical partition space (vs. e.g., hash chain length)
[17:25:25] <wiesand> The inf.ed.ac.uk guys tend not to be fools. But I'm fairly sure the solution for this is not on the openafs end.
[17:25:40] <kaduk@jabber.openafs.org/barnowl> So if 1.8.x is the top priority, are there areas where more hands will
help?
[17:26:26] <wiesand> Unfortunately, I'm the blocker right now :-(
[17:26:29] <kaduk@jabber.openafs.org/barnowl> agreed about the inf.ed.ac.uk guys, though that's a different thread
than the one I was mentioning
[17:26:49] <kaduk@jabber.openafs.org/barnowl> ("openafs volume corruption when partition usage above 95%", which
ended up in my spam folder)
[17:27:07] <kaduk@jabber.openafs.org/barnowl> (https://lists.openafs.org/pipermail/openafs-info/2020-January/042899.html)
[17:27:41] <mvita> inf.ed.ac.uk had the panic which seemed likely jbd, not afs
[17:27:54] <kaduk@jabber.openafs.org/barnowl> Oh wait!  1.6.15 is old even for the 1.6.x branch; I should have
looked for fixes on the branch, first
[17:27:56] <meffie> i think it is pretty common to run at more that 95% full. we do it all the time (sadly)
[17:27:59] <wiesand> ok, confused those
[17:28:29] <meffie> i suppose we need to ask him for more details.
[17:30:37] <kaduk@jabber.openafs.org/barnowl> perhaps so
[17:31:12] <wiesand> i avoid running at more than 95% full if i possibly can
[17:31:58] <wiesand> actually, that would trigger an alert and make me move volumes
[17:32:49] <meffie> some investigation will be needed. i'll ask him for more details.
[17:32:59] <wiesand> thanks!
[17:33:03] <kaduk@jabber.openafs.org/barnowl> Thanks!
[17:33:08] <mvita> what I find surprising is not problems at 95% but the symptom that was presented - very odd
[17:33:17] <meffie> yes
[17:33:20] <kaduk@jabber.openafs.org/barnowl> indeed
[17:33:33] <meffie> more information is needed.
[17:33:47] <mvita> Mike suggested the 95% may be a red herring, and I think that's likely as well
[17:33:49] <kaduk@jabber.openafs.org/barnowl> (FWIW, openafs-stable-1_6_15..origin/openafs-stable-1_6_x looks pretty
boring)
[17:34:22] <meffie> which reminds me; mark vitale found a nice issue with recent versions of rsync and afs.
[17:34:28] <wiesand> in the context of that bur report, anyway
[17:34:31] <mvita> oh that old thing
[17:35:12] <mvita> sorry, I've got to step away early, I've got a lunch appt
[17:35:17] <wiesand> is there a change to fix it?
[17:35:37] <wiesand> Bye Mark, thanks for joining us today. Enjoy your lunch.
[17:35:49] <mvita> the rsync thing?  There are operational changes you can make in AFS to avoid provoking it, but it's actually an rsync bug
[17:36:38] <mvita> I'll be reporting it to the rsync project (I was able to bisect to the faulty rsync commit)
[17:36:50] <wiesand> thanks!
[17:37:06] <kaduk@jabber.openafs.org/barnowl> cool, and thank you!
[17:37:13] <meffie> maybe after the that report, we can point it out on the -info list?
[17:37:20] <mvita> okay
[17:37:24] <meffie> just to warn others :)
[17:37:28] <mvita> gotta go now…
[17:37:34] <meffie> ok, thanks!
[17:37:58] <kaduk@jabber.openafs.org/barnowl> yes, thanks, and enjoy your lunch!
[17:39:52] <wiesand> So I'm still woking on the next 1.8.x prerelease. Alas, this week's time slots mostly got stolen by other issues again.
[17:40:12] <wiesand> The goos news is that it can probably only get better.
[17:40:22] <wiesand> s/goos/good/
[17:41:11] mbarbosa leaves the room
[17:42:07] <wiesand> Other issues to discuss today?
[17:42:52] <meffie> nothing else here.
[17:43:12] <kaduk@jabber.openafs.org/barnowl> It was a somewhat rough week for me as well, but next week is looking
better.
[17:43:30] <kaduk@jabber.openafs.org/barnowl> Making some progress on that freebsd stack now, that last week I
described as "daunting" (IIRC)
[17:44:22] <kaduk@jabber.openafs.org/barnowl> I don't think I have other topics, though
[17:44:27] <kaduk@jabber.openafs.org/barnowl> anyone else?
[17:46:09] <meffie> just continuing to push cleanups to master.
[17:46:22] <kaduk@jabber.openafs.org/barnowl> I will try to keep up :)
[17:46:36] <kaduk@jabber.openafs.org/barnowl> they've been good stuff so far, so keep 'em coming
[17:46:38] <meffie> ok, thank you!
[17:47:34] <kaduk@jabber.openafs.org/barnowl> thank you!
[17:47:40] <kaduk@jabber.openafs.org/barnowl> Motion to adjourn?
[17:47:58] <meffie> ok, have a good weekend. wiesand let me know if there is anything i can do to help with 1.8.x since that is your priority.
[17:48:27] <kaduk@jabber.openafs.org/barnowl> > have a good weekend
thanks; you too
[17:56:22] <wiesand> sorry, got distracted
[17:56:48] <wiesand> mike: will doo, but as i said i'm the blocker right now
[17:56:59] <wiesand> thanks a lot everybody!
