BBS: TELESC.NET.BR Assunto: Adding a hardware swap partition De: bp Data: Thu, 12 Mar 2026 10:00:01 +1100 ----------------------------------------------------------- Is there a "recipe" for adding a hardware swap partition to an existing RasPiOS installation? Ideally I'd like a traditional layout, with swap situated between / and /usr. I know how to do it with FreeBSD during the install process but this particular case involves a running, somewhat valuable RasPiOS installation and the tools offered on RasPiOS are different enough to warrant a study of prior art if it's available. What I'd like to do is resize the existing root to roughly its present, occupied size, add a swap partition in the freed space and then create /usr in the remaining space, copying the old /usr to the new, cleaning out usr files from the original root partition and mounting the new /usr on the empty mountpoint. This needs to be done under single-user mode and I don't know how to get at single-user in RasPiOS. It could be done via booting from a microSD, but that pitches me into the installer which isn't exactly familiar territory. In case it matters, this is on an 8GB Pi5 running Bookworm with dual monitors and a 1 TB mechanical hard drive. df reports Filesystem 1K-blocks Used Available Use% Mounted on udev 4081296 0 4081296 0% /dev tmpfs 1650304 6512 1643792 1% /run /dev/sda2 961067256 61907904 850331260 7% / tmpfs 4125728 163136 3962592 4% /dev/shm tmpfs 5120 48 5072 1% /run/lock /dev/sda1 522230 79520 442710 16% /boot/firmware tmpfs 825136 272 824864 1% /run/user/1000 The need for "real" swap arises when Chromium and Firefox are both running with multiple tabs open.
