Re: OpenBSD Hackathons
Hi all, Thank you for the helpful responses, this definitely explains some things! I'm looking at organizing an OpenBSD Hackathon in the National Capital Region in Canada (could potentially be on the Gatineau, Quebec side) but having never been to an OpenBSD Hackathon, my interpretation might be quite different from the other Hackathons! That's fine, and I'm going to seek inspiration from attending a FreeBSD Hackathon, as that project makes their upcoming Hackathons public: https://wiki.freebsd.org/Hackathon/202305 Thank you very much for the help and please feel free to contact me privately if you're interested in attending (either as a volunteer or developer) or otherwise supporting an OpenBSD Hackathon in the National Capital Region in Canada.

Re: What is the best way to move a VM to a bigger image?
Hello everyone, And now the conclusion. I indeed ran the installer to get partitioned disk easily and the result was just the bsd and base file set installed system. That system worked fine. Then I dumped and restored the partitions or filesystem as FAQ instructs. Anyway I got sha256 identical systems except /dev, /tmp and /etc/fstab The comparison was interesting. $ find / -type f >/tmp/files.txt $ wc /tmp/files.txt 10 100572 5291532 /tmp/files.txt That was weird. No-one should have exactly 100k files in their system. I don't understand why during startup all programs just dumped core. I would suspect some library randomization. After re-installing bsd and base fileset again the new disk booted nicely. I believe relinking the kernel and other end of installation steps would probably be enough to fix that kind of problem. So that was my way of doing this operation. Best regards, Hannu Vuolasaho

Re: OpenBSD Hackathons
I was invited to one many years ago, for one reason or another I declined. So if you ever get invited I suggest you jump at the opportunity. 73 diana On May 12, 2023 2:07:57 PM MDT, Anders Andersson wrote: >On Fri, May 12, 2023 at 9:39 PM Katherine Mcmillan wrote: >> >> Hi Stuart, >> >> Thank you for your response.

Perhaps it might be an idea to develop another tier of these to develop exactly that. If only 5% go on to contribute something of value, whether that be coding or docs, it may well be worth it. It would also contribute to aspects such as community building which, for a number of community- based projects (and one or two quite notable ones) is an aspect which is under-appreciated these days. Just some thoughts, but community-based projects are only as healthy as their communities. Cheers! -- A Kiwi in Australia, doing my bit toward raising the national standard.

I have no experience with hackathons except when working for a globally recognized company that had no idea what a hackathon meant but tried to do a few. When I learned that leadership set up a process to accept what could be hacked on, and a process to determine the winning team of the hackathons, I decided to skip the events. :-( Anyway, the official OpenBSD hackathons are limited to a select group. There is no minimum size, I assume, because if these people want to meet up then they do. If you want to set up your own community OpenBSD hackathon then you will need to do the advertising, signup process, and management of the location/capacity vs signups, etc. yourself. I do hope it goes well! Justin

vfs.nfs.iothreads - how much is safe?
Hello, I found an option while reading man mount_nfs: "Use sysctl(8) or modify sysctl.conf(5) to adjust the vfs.nfs.iothreads value, which is the number of kernel threads created to serve asynchronous NFS I/O requests." I tried to raise this value to a maximum of 20 and saw a decent speedup in file transfer without any visible issue. But when using dd to write a 1GB zero file to an nfs share just for fun I saw my system become a little unresponsive while dd was running (my mouse was moving interruptedly): # dd if=/dev/zero of=/nfs_share/testfile bs=1000M count=1 How safe is it to raise this value to its maximum of 20? -- Maksim Rodin

Usually it's a network problem. The big delay of 3 days you had also suggests that. But on the other hand, I also had a similar problem in one of my load balancers (routing/fw/relayd), where the MASTER was becoming BACKUP for no obvious reason. I believed it was a network glitch, but couldn't trace it. The problem after all was that they where pushing the limit of max pf states and relayd checks where failing. Not obvious to spot at all. I believe default is 20K. pfctl -sm pfctl -si After increasing that limit with set limit states I've never had a glitch any more. G

You can also look at netstat -ni -I ixl0 netstat -ni -I ixl0 -e kstat ixl0::: which may give some other clues even pfctl -si might have something relevant > Several people pointed out I was using the default advskew of 1 second, > which means a small network glitch (or system load? maybe I'm all wrong > about this system never breaking a sweat, at least when it comes to > network traffic) would flip it, so I've increased it to 10 on both > machines (and apparently just induced a flip of my own. oops).
