Kilroywhere would I look to see why a drive is not mounting?00:26
sarnoldtry to mount it and see if there's any errors given directly, or in dmesg00:27
Kilroyit did not give any errors just won't mount00:27
Kilroyok I get this from dmsg00:28
KilroyFeb 16 18:28:03 sturtz.cf systemd[1]: data.mount: Unit is bound to inactive unit dev-disk-by\x2did-dm\x2duuid\x2dLVM\x2dMudyLBQKlDEZZpEagNRQt6z7Zj0uXzJMwQZCyGC8JnBSpt6pvJOY2GhQsspYD7I0.device. Stopping, too.00:28
Kilroywhat does that mean?00:29
Kilroyah00:35
Kilroyfixed it 00:35
Kilroyjust had to run systemctl daemon-reload00:35
sarnoldah, nice :) I had no idea on that one00:36
Kilroyjust a bit of searching (I forgot about the web) https://www.claudiokuenzler.com/blog/1124/linux-mount-not-working-systemd-unit-is-bound-to-inactive00:37
sarnold*wild*00:39
Kilroyanybody know what fliesystem type would be the best for storage?00:39
Kilroylike a cloud storage00:39
sarnoldI like zfs; ext4 is kind of a default but I don't think it'll go quite as far00:41
Kilroywhat about xfs00:42
Kilroy(I could not find zfs)00:42
sarnoldI understand xfs is redhat's default, so it's probably got some good qualities to it, but it's less common in ubuntu-land00:43
Kilroyok00:43
sarnoldthis series of blog posts is pretty old now but does a good job of introducing zfs https://pthree.org/2012/12/04/zfs-administration-part-i-vdevs/00:43
Kilroyok thank you00:44
sarnoldskip the "install" post, on ubuntu it's just apt install zfsutils-linux   :)00:44
Kilroyok thank you00:45

odenHi. I'm using a Moxa Technologies Co Ltd CP-114EL (4-port RS-232/422/485 Smart PCI Express Serial Board) and want to "hard code" so that /dev/ttyS4 always is /dev/ttyS4. Right now it's /dev/ttyS7 no matter which one of the four ports I connect a device to. 07:15
oden# grep -v unknown /proc/tty/driver/serial | tail -407:17
oden4: uart:ST16650 mmio:0x92C00000 irq:16 tx:0 rx:007:17
oden5: uart:ST16650 mmio:0x92C00200 irq:16 tx:0 rx:007:17
oden6: uart:ST16650 mmio:0x92C00400 irq:16 tx:0 rx:007:17
oden7: uart:ST16650 mmio:0x92C00E00 irq:16 tx:0 rx:0 RTS|DTR07:17
odenSo, if I change to the connector marked P1 (/dev/ttyS4) it does not matter in the above command.07:19
odenI don't really know what to do here.07:20
odenI mean, if I put the device in P3 I would expect "6: uart:ST16650 mmio:0x92C00E00 irq:16 tx:0 rx:0 RTS|DTR" but no.07:22
odenOuch. Never mind this. It was operator bork07:35

odcHi! I have a question about the ubuntu/bin9 docker image (https://hub.docker.com/r/ubuntu/bind9). I understand it is managed by the Ubuntu Server team. This seems to be a very used image, yet it is marked as "beta". Why isn't there a "stable" version? Should I use this in production?10:16
rbasaksergiodj, athos: ^10:25
fricklerodc: this seems relevant https://bugs.launchpad.net/ubuntu-docker-images/+bug/195531810:37
ubottuLaunchpad bug 1955318 in Ubuntu Docker Images "Docker Image for ubuntu/bind9 tagged incorrectly" [Undecided, New]10:37
odcgood find frickler :)10:43
odcso I wonder why they've never selected a "stable" version. I guess bind is not used a lot these days...10:45

evitWas there an update to SSH on Ubuntu 18.04 in the last few days? I recall seeing one but I don't see it in security notices...11:50
andolevit: Yes, https://launchpad.net/ubuntu/+source/openssh/1:7.6p1-4ubuntu0.611:54
andolNot all updates are security updates.11:54
andol...and yes, I'm too a bit confused by the date in the changelog.11:56
ahasenackgood morning11:57
evit@andol, Yes, indeed. With all the supply chain attacks I was having a freak out moment. =X12:07
rbasakandol: it was prepared a long time ago, but the update wasn't issued because nobody was identified who still needed it. Until recently.12:09
evit@andol, sometimes updates to the sec notice page come in a delayed fashion too. 12:09
evitNot complaining, just sayin'12:09
athosgood morning!12:12
athosodc: The process of promoting the published OCI images is still being designed. That question seems to be fit to start a discussion in the bug frickler linked here though :)12:17
odcthanks athos! Hurry up guys :p12:33

bryycehi lena, thanks for reviewing the mysql apport hook MP when you get time.  I've added some tips on what is good to test and consider in doing the review.17:17
bryycelvoytek, our team's official docs on doing MP reviews is at https://github.com/canonical/ubuntu-maintainers-handbook/blob/main/MergeProposalReview.md; it has a handy checklist17:18
bryycelvoytek, the page with the MPs to review is https://code.launchpad.net/~canonical-server/+activereviews (worth bookmarking if you haven't already).17:19
lvoytekbryyce: Thanks! I'll get started on that soon18:24

sergiodjahasenack: hey, any news on that winbind bug we were discussing yesterday?19:25
ahasenackno, didn't check19:25
smoserI wonder who would care to review https://github.com/smoser/talk-simplestreams/pull/1319:28
ubottuPull 13 in smoser/talk-simplestreams "Update maas3 daily stream url, add maas3-release." [Open]19:28
smoserphilroche and Odd_Bloke were last ones to touch it.19:28
sergiodjahasenack: is this in your TODO list, or is it something you don't plan to tackle soon?  asking because I'd then have to add it to my TODO list19:29
ahasenackit's written down19:29
sergiodjOK, thanks.  let me know if you need help19:30
smoserahasenack  or blackboxsw  ?19:31
ahasenackmaybe someone from maas?19:33
ahasenackare you saying the "stable" url now has the "daily" content?19:33
ahasenackI pinged the maas team19:40
smoserahasenack: i think that they just started publishing daily as stable19:52
smoseri think they're probably the same filesystem under neitht19:52
ahasenackI remember back in the day noone was crazy to run "stable", all went for the daily stream19:53
ahasenackas "stable" was really never updated19:54
ahasenackbut I'd think the fix for that would be to update stable, instead of calling daily == stable :)19:54
blackboxswsmoser: I'll also get a prelim review on this today. Wanted to understand the context of the url changes in general from MAAS too.20:11
smoserahasenack: don't shoot hte messanger on that.20:20
ahasenacksergiodj: that winbind bug, it worked fine locally, but this is just a very small AD with one client connected to it, I didn't really expect otherwise21:31
ahasenacksergiodj: there is this interesting remark in the winbindd manpage, though21:31
ahasenack       SIGHUP21:31
ahasenack           Reload the smb.conf(5) file and apply any parameter changes to the running version21:31
ahasenack           of winbindd. This signal also clears any cached user and group information. The21:31
ahasenack           list of other domains trusted by winbindd is also reloaded.21:31
ahasenackso if you have a ton of users cached, that simple logrotate will clear the cache21:31
ahasenackthat might explain why it's sluggish after that, and also why a restart takes a minute21:32
sergiodjinteresting21:32
sergiodjwell, to me it seems like a possible Incomplete/request-more-info kind of bug, but with the above as a possible cause21:33
sergiodjwould you like to update the bug or should I?21:33
ahasenackI'm adding something, but this is one of those where to investigate further, a lot of time will have to be spent21:34
sergiodj(thanks for the further investigation, btw)21:34
ahasenackI can ask some bits there that are missing21:34
sergiodj+121:34
ahasenackI'm adding a comment, take a look in a few to see what you think21:34
sergiodjwill do, thanks21:34
ahasenackthat being said, it's unclear if smbcontrol uses sighup21:36
ahasenack`The winbindd destination causes the message to be sent to the winbind daemon specified in the winbindd.pid file.`21:36
ahasenacktime to strace21:36
sergiodj:)21:37
ahasenack7993  openat(AT_FDCWD, "/var/run/samba/winbindd.pid", O_RDONLY|O_NONBLOCK) = 821:38
ahasenack7993  read(8, "5365\n", 19)             = 521:38
ahasenack7993  kill(5365, SIG_0)                 = 021:38
ahasenackwhat's SIG_0?21:38
sergiodjSIG_0 is usually used to obtain the PID21:39
sergiodjsorry, I mean, to actually consult whether that PID is still alive21:39
sergiodjit does nothing21:40
ahasenackok, then it's using something else21:40
ahasenackand that manpage remark doesn't apply21:40
ahasenackyeah, it opens a unix socket afterwards21:40
ahasenackbut maybe internally relaod-config has the same effect21:41
ahasenack`/* React on 'smbcontrol winbindd reload-config' in the same way as on SIGHUP*/21:42
ahasenack`21:42
ahasenackok, it's the same21:42
ahasenackok, posted something21:46
sergiodjthanks21:48
sergiodjdo you mind if I set the bug as Incomplete?21:49
