Cron not executing @reboot command in crontab
Hello, I apologize if this is trivial, I genuinely read through all the cron- related manpages and tried several things, but this is my issue: I want to use 'autossh' to automatically establish reverse port forwarding on boot, so (as root) I can 'crontab -e' and added this line to the bottom: @reboot autossh [all my options] After adding the line, running 'crontab -l' shows that the line was correctly added; I have also confirmed that the 'autossh ...' part works perfectly when I just execute it in a terminal. When I reboot the system though, nothing happens. Even if I restart cron with rcctl, nothing happens. I even confirmed that sshd is started before cron in rc, I have tried everything I could come up with, I just have no clue what I'm missing. Since I am new to OpenBSD, I would appreciate your advice or any clues on what I have done wrong. Regarding system setup, this is a completely bare system, I have just run 'sysupgrade -s' and installed autossh. Thank you in advance!

At the top of the file you'll see:
PATH=/bin:/sbin:/usr/bin:/usr/sbin
Either {pre,ap}pend /usr/local/{,s}bin or use the full command path.

Starting redis fails with 'Bus error (core dumped)'
Hello again, I am currently setting up redis with rspamd for my mail setup, but I am encountering an issue when trying to just start redis. For the record, I am following the guide at https://poolp.org/posts/2019-09-14/setting-up-a-mail-server-with-opensmtpd-dovecot-and-rspamd/ After installing redis (and rspamd), before having modified any part of redis, starting redis with 'rcctl start redis' fails. I then tried running the binary itself in /usr/local/sbin/redis-server, which only returns 'Bus error (core dumped)'. I changed the log level in the '/etc/redis/redis.conf' to debug, but do not get any more information about the reason for failure. Running 'grep -R redis /var/log/' did not give me any information either, and after changing the log level to debug, the only thing that changed is an unreadable 'redis-server.core' file appearing in '/var/log'. I'd very much appreciate your help, thanks in advance! Best, Unicorn
Boot failure on XPS 13/9380 (but bsd.rd works)
As per the subject, bsd.rd boots and the installation proceeded as usual. Another laptop saved from ever booting the mess it came preinstalled with. Yay. Subsequently rebooting results in the following (bsd.sp does the same with different addresses): probing: pc0 mem[632K 475M 255M 208M 137M 150080M] disk: hd0 >> OpenBSD/amd64 BOOTX64 3.46 boot> booting hd0a:/bsd: 12748104+2941960+34+0+708608 [986153/ I tried booting the 6.5 installer to see if I could find a point between in which it broke but it stops every time after the kernel's penultimate line (between 'scsibus2 at softraid0: 256 targets' and reporting the root device). Interestingly 6.6 also did this once which was seemingly related to having warm-booted immediately prior but it only did it the once whereas 6.5 seems to be consistent. Nevertheless I wasn't paying attention to what the 6.6 installer was doing at the time so I'll look into that some more. I traced the boot process through to loadfile in libsa so I know that it's stuck while reading the ELF symbols (it gets at least as far as the first PROGRESS line after "Now load the symbol sections themselves") but that's probably obvious to whoever knows the boot code. Personally I haven't much clue what should be happening and it's clearly not happening as it should anyway so I don't know what to poke at to get more clues to fall out. The below was extracted by running sendbug -P from within the installed OS (chroot) while running the 6.6 bsd.rd and then doing whatever crazy thing I'm going to need to do to get them onto here. It complained about a lack of /var/db/acpi/* so if they're useful and can be generated from the ramdisk kernel then I can get them too. The dmesg is from the installer's /var.

Re: Home NAS
Hi, I found it, there exist glastree which is available from ports. Nice small "poor man's" backup as the author qualifies, though makes incremental backup through hard links: # if yesterday does not exist or today is newer, copy the file # else hard link the file to yesterday Ports: http://ports.su/sysutils/glastree Source: https://github.com/jeremywohl/glastree You can simply run it from crontab and even setup a short time daily and long time monthly or what ever else suits best through running the utility with different configurations from multiple crontab lines (daily, monthly, etc ...) glastree-1.04p0 – poor man's daily snapshot The poor man's daily snapshot, glastree builds live backup trees, with branches for each day. Users directly browse the past to recover older documents or retrieve lost files. Hard links serve to compress out unchanged files, while modified ones are copied verbatim. A prune utility effects a constant, sliding window. Satoru Takabayashi has written a similar program, in Ruby, pdumpfs. Inspired by Plan9, of course.

Re: Boot failure on XPS 13/9380 (but bsd.rd works)
I'd quite like to debug this problem. I'm looking through the code now to find out where I can inject some sort of printf-like statement to glean some information about what it's [not] doing and may eventually even get somewhere. I'll continue to do this regardless because I'm bored and I just spent a crapload of money on this thing and I'll be damned if it's going to not work on me and I want to use _this_ OS goddamnit, but if anyone can point me to resources to read or other hints about how to debug code running at such a low level before the OS has had a chance to take over, they would be greatly appreciated. I've been coddled for a long time and working on the bare metal like this is alien to me. Thanks, Matthew ps. Apologies if the list threading is screwed up. I can't reply to my own messages apparently.
Modifying installXX.iso via script
Hello list, I created an autoinstall bsd.rd (containing auto_install.conf and disklabel.conf) and a siteXX.tgz. For example with the tool isomaster I can manually edit the install66.iso and add bsd.rd and site66.tgz to the directory 6.6/amd64. This modified ISO can be booted from real and virtual hardware. The unattended installation works and is really cool! Now I want to go the extra step and automate the modification of the installXX.iso. I tried the tool xorriso: $ ls -l 6.6/amd64/ total 28544 -rwxr-xr-x 1 null null 10299545 Nov 17 18:00 bsd.rd -rw-r--r-- 1 null null 4680444 Nov 17 05:03 site66.tgz $ xorriso -indev install66.iso -outdev install66a.iso -boot_image "any" "keep" -add 6.6/amd64/ [1] This leads to this message when trying to boot: CD-ROM: E0 Can't find /cdboot I then moved cdboot from 6.6/amd64 to the root of the CD: $ xorriso -indev install66.iso -outdev install66a.iso -boot_image "any" "keep" -move 6.6/amd64/cdboot cdboot -add 6.6/amd64/ This leads to this message when trying to boot: CD-ROM: E0 Loading /CDBOOT probing: pc0 mem[639KB 2046M a20=on] disk: hd0+ cd0 >> OpenBSD/amd64 CDBOOT 3.44 boot> cannot open cd0a:/etc/random.seed: No such file or directory booting cd0a:/6.6/amd64/bsd.rd: open cd0a:/6.6/amd64/bsd.rd: No such file or dir ectory failed(2). will try /6.6/amd64/bsd.rd boot> When I move bsd.rd to the root of the CD too, I can at least start the installation by typing boot> bsd.rd But it would be nice if that wouldn't be necessary. When looking at the ISO files with isomatser, the only difference I can find is that on the modified ISO the publisher information is in all caps. I'm obviously doing something wrong.

I have put an insane amount of work into exactly this, also with
an eye to portably directing the process to other operating systems
and hosting environments.
I'd be very interested to hear more about what your working on but
meanwhile I think the command you're looking for is some variant
on this:
mkiso() {
# Create new iso
# From src/distrib/amd64/cdfs/Makefile
if on_openbsd; then
OSREV=$os_version # For easier copy pasta
mkhybrid -a -R -T -L -l -d -D -N -o "$iso_fn" -v -v\
-A "OpenBSD ${OSREV} amd64 autoinstall CD" \
-P "Copyright (c) `date +%Y` Theo de Raadt, The OpenBSD project" \
-p "Theo de Raadt " \
-V "OpenBSD/amd64 ${OSREV} boot-only CD" \
-b ${OSREV}/amd64/cdbr -c ${OSREV}/amd64/boot.catalog\
"$s_where"/cd
# -a all-files
# -R Rock Ridge
# -T TRANS.TBL
# -L Allow .-file
# -l allow 32char
# -d Omit trailing period
# -D not use deep directory relocation, ... Use with caution.
# -N Omit os_version numbers ... Use with caution.
# -o "$iso_fn"
# -v -v verbose
# -b boot_image
# -c boot_catalog
else
die_unsupported build/target combination
fi
}
mkhybrid and xorriso are basically the same tool in ways I can't
quite remember right not but could probably be persuaded to. An
invocation of one can be systematically converted into an invocation
of the other.
Enjoy.

Thank you for your quick response. It works now. Even better that the

Best Practices for growing disk partitions on a server
Hi folks, I am new to openBSD, so forgive me if I am missing something obvious. I recently installed openBSD on a server using the auto-partition layout during installation and am quickly starting to run out of disk space. I have read the section in the FAQ [1] regarding how to grow a disk partition, but I am confused on the best way to actually do this. Specifically, I am trying to grow /usr and /home but they are "busy" when I try to follow these steps on a running server. Is the assumption that you are supposed to reboot the server with the ISO attached and pop into a shell to complete these steps?

How is DF NFS server related to OpenBSD (if I understand correctly) virtualization. Are you trying to store OpenBSD vmm images on the NFS share exported from a DF server?

Tape drive
Hi all, I am currently struggling to get a tape drive to work on a OpenBsd box I've recently installed, I must say I am new to this devices (tape drive) and I have not used them before. I am running : OpenBSD .my.domain 6.3 GENERIC.MP#9 amd64 On a x86-64 Dell, the tape drive is an HP StorageWorks Ultrium 960.I haven't done much to set-up the device and it is apparently getting recognized as the command sees it: # mt -f /dev/rst0 status SCSI tape drive, residual=0 ds=3 er=0 blocksize: 1024 (1024) density: 0 (0) I did set the block type while testing but it does not make any difference, it seems that I can write with no issues to the device but I am having issues while reading: # tar cf /dev/rst0 ./test.txt # mt -f /dev/nrst0 rewind # tar xf /dev/rst0 .out tar: Failed read on archive volume 1: Input/output error tar: Unable to recover from an archive read failure. tar: Sorry, unable to determine archive format. What can I do to diagnose the problem ? Using other utilities such as pax did not make any difference. Thanks, Pietro

This makes sense, but I was curious what the recommended approach is for a server that you cannot simply reinstall.

Since 2008 if you are ZFS on FreeBSD or Hammer 1 DragonFly guy. XFS is indeed the most stable and reliable file system for Linux and in principle there is nothing wrong with using XFS on the top of hardware or software RAID if you don't care about data integrity, self-healing, COW, snapshots, replication and similar things. If you put LVM2 between the RAID and XFS you could theoretically get snapshots of logical volumes and perhaps even restore something. However LVM2 snapshots are expensive and not really practical contrary to Red Hat PR debarment claims. Hopefully some of old Irix SGI who are lurking on this mailing list could tell you more things I don't know or I forgot since my old Irix days. Pozdrav, Pedja > Cheers > Milun

Or people who do not want to swap while doing extensive fsck of huge partitions with lots of small files in them. Most recommendations are based on all corner cases and not just the happy-case when you stash a single movie on a nas over the home network. Yes, dedup uses ram most of the time if it can, but other things do too. Also, "excess" ram in these cases turn into read caches so its not lost on you either. -- May the most significant bit of your life be positive.
