tl;dr Creating a swapfile with fallocate should work on XFS now. Found this thread from about 3 years ago https://www.spinics.net/lists/linux-mm/msg147100.html There were a few things that needed work to fix it, and I'm not sure which one finally did it, but this 2019 patch was part of that series: https://lore.kernel.org/linux-xfs/20191008071527.29304-16-hch@xxxxxx/ That is in 5.7, which is what Fedora 33 shipped with. https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/fs/xfs/xfs_aops.c?h=v5.7 Anyway...even though I can't nail down exactly when it got fixed, today I asked the XFS maintainer about all of this and he said fallocate'd swapfiles should work. And I also tested it with kernel 5.11.16 and 5.12 and it does work. -- Chris Murphy _______________________________________________ cloud mailing list -- cloud@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to cloud-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/cloud@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
