Public bug reported: The swapfile generated on the current Ubuntu on Raspberry Pi dailies for jammy includes holes which prevents the swapfile from activating on boot. After digging through livecd-rootfs and ubuntu-image I *think* this might be a problem introduced by the latter. However, this seems to come up periodically so rather than repeatedly trying to squash the problem let's just avoid it entirely by having the swapfile allocated on first boot. Using fallocate for this (instead of dd'ing /dev/zero) works happily and is extremely quick.
I've proposed the following merge against ubuntu/master which implements this change (and cleans up some cruft in the fstab handling; that's in a separate commit though -- happy to remove it if wanted): https://code.launchpad.net/~waveform/livecd-rootfs/+git/livecd- rootfs/+merge/415625 The change has been tested on the armhf and arm64 preinstalled jammy dailies and works happily. My one concern was that the file-system expansion must happen prior to the swapfile allocation, but given systemd is handling the expansion, and the allocation has "After=local- fs.target" specified, this appears to be sufficient for everything to run in the correct order. ** Affects: livecd-rootfs (Ubuntu) Importance: Undecided Status: Confirmed ** Affects: livecd-rootfs (Ubuntu Jammy) Importance: Undecided Status: Confirmed ** Tags: raspi-image ** Also affects: livecd-rootfs (Ubuntu Jammy) Importance: Undecided Status: New ** Changed in: livecd-rootfs (Ubuntu Jammy) Milestone: None => ubuntu-22.04 ** Tags added: raspi-image ** Summary changed: - swapfile has holes + swapfile has holes on preinstalled desktop ** Changed in: livecd-rootfs (Ubuntu Jammy) Status: New => Confirmed ** Merge proposal linked: https://code.launchpad.net/~waveform/livecd-rootfs/+git/livecd-rootfs/+merge/415625 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1961047 Title: swapfile has holes on preinstalled desktop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/livecd-rootfs/+bug/1961047/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
