It could be missing drivers or firmware, it would be nice to see a dmesg or lsmod from a working system with said USB disk & the non-working system.
I.e. to identify if 21.10 is somehow missing some kernel modules, or firmware. Note that in 21.10 we have split raspi modules into two packages, does your procedure installs and configures linux-modules-extra-raspi ? such that more drivers are available. ** Also affects: linux-raspi (Ubuntu) Importance: Undecided Status: New ** Changed in: linux-raspi (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-raspi in Ubuntu. https://bugs.launchpad.net/bugs/1964082 Title: MAAS deployment to raspberry pi fails for release 21.10 Status in MAAS: New Status in linux-raspi package in Ubuntu: Incomplete Bug description: I have helped develop a reliable procedure for using MAAS to deploy ubuntu 20.04 to a Raspberry Pi cluster. Details are here: https://discourse.maas.io/t/build-your-own-bare-metal-cloud-using-a- raspberry-pi-cluster-with-maas/5845 However, using the same procedure on the same hardware but selecting ubuntu 21.10 always fails. This appears to be caused by curtin being unable to see the USB disk device /dev/sda to which we are deploying. The same issue occurs with all versions of the kernel available for 21.10. I enclose the log files downloaded from MAAS.
