Hi, My team runs Ubuntu 20.04 on EC2. We use the cloud images that Canonical and AWS publish for Ubuntu as our base image. As part of the first boot of one of these images, cloud-init runs resiz2fs in order to make the root filesystem match the size of the root volume on which the instance is provisioned.
A few times a week, this would fail for us, which results in instances that have an unexpectedly small root filesystem. We were able to build a reproducer for the problem, debug it, and get it fixed upstream. There's a patch in the main branch of e2fsprogs with the fix now. We've had to fork the Ubuntu version of e2fsprogs to carry this patch, but from our analysis it ought to impact (potentially) any customer running on EC2. Would Ubuntu be willing to backport this patch to the versions for which they build EC2 AMIs? (We're specifically interested in any LTS Ubuntu releases). I logged a ticket for this on launchpad here (it includes the reproducer): https://bugs.launchpad.net/ubuntu/+source/e2fsprogs/+bug/2036467 The patch itself is a 2-line change: https://git.kernel.org/pub/scm/fs/ext2/e2fsprogs.git/commit/?id=43a498e938887956f393b5e45ea6ac79cc5f4b84 The thread where this was discussed with the upstream maintainer is here: https://lore.kernel.org/linux-ext4/20230609042239.ga1436...@mit.edu/ Thanks very much, -K -- Ubuntu-devel-discuss mailing list Ubuntu-devel-discuss@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel-discuss
