Hi Michael, In order to confirm whether we're talking about the same bug here, I tried to reproduce it. Here's what I did:
1) Grab a Focal machine, up-to-date. 2) Run "lxd init" and make sure to choose "zfs" as the backend format for its storage. 3) Fire up a Focal VM using "lxc launch ubuntu-daily:focal fallocate- focal --vm". 4) Shell into the VM, and perform the steps described in the "Steps to reproduce" section from the description. Here's what I see: root@fallocate-focal:~# touch foo.img root@fallocate-focal:~# fallocate -z -l 10M foo.img root@fallocate-focal:~# ls -la foo.img -rw-r--r-- 1 root root 10485760 Aug 4 01:02 foo.img It seems to me that this is working according to what's expected, at least when we consider the fallocate bug that's been originally fixed in Jammy. Maybe you're experiencing a different problem? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to zfs-linux in Ubuntu. https://bugs.launchpad.net/bugs/1969247 Title: fallocate with FALLOC_FL_ZERO_RANGE produces zero-size files on zfs in Jammy Status in Native ZFS for Linux: Fix Released Status in mysql-8.0 package in Ubuntu: Invalid Status in zfs-linux package in Ubuntu: Fix Released Status in zfs-linux source package in Jammy: Fix Released Bug description: [Summary] When running Jammy on zfs or LXD with a zfs pool on a Jammy host, fallocate creates a zero-sized file. The issue was originally found when installing mysql on LXD, where fallocate would create a zero-sized ib_logfile1 file. The original information in this bug is based on that. [Steps to Reproduce] touch foo.img fallocate -z -l 10M foo.img ls -la foo.img On a non-zfs Jammy system this will show something like: -rw-r--r-- 1 root root 10M ... while on zfs it will show: -rw-rw-r-- 1 root root 0 ... [Original Description] I came across this error when testing various mysql setups in an LXD container and managed to reproduce it consistently. I'm unable to reproduce on Ubuntu desktop or server though since the prerequisites are probably handled properly there.
