The use of the 'b' partition on the root disk for swap is controlled by the following line in the kernel config: config bsd swap generic I was wondering whether you had changed this, or left it as-is and simply not created a 'b' partition. > Is this known? We've known about it for over a year. It's mentioned in our guide to running OpenBSD on SBCs: https://www.exoticsilicon.com/jay/sbc_bootcamp_2021 The issue is NOT reproducable on amd64. Running swapless on amd64 with >= 32GB of physical RAM is our default. Even our VMs at OpenBSD Amsterdam, handling all of our smtp, dns and web traffic run swapless, and always have done. We see zero stability issues with this on amd64, so it's either specific to arm, or for some reason the issue is mitigated on amd64. > There is something else going on on the swap partition, > even of not used for lack of physical ram: for example, > now that I run with the swap partition, I can remove it > with swapctl -d, but cannot remove it from the disklabel > because disklabel: DIOCWDINFO: Device busy. Well, by default it's the configured dump partition too.
