Comment 43 for bug 1969247

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?
