Dear Maintainer,

Presently, zfs-linux fails when running draid tests from
kernel-smoke-tests in debian/tests on s390x architecture with
the following error:

"kernel smoke test, create and destroy pool, draid1: FAILED: zpool create failed, exit code=1"

I have logs available if necessary, and have access to a s390x
machine to aid with testing if helpful.

I rebuilt the Debian package using the latest upstream (https://github.com/openzfs/zfs), and saw the same error. Log is (hopefully attached). Will raise the issue there as well.


Thanks,
John

Upstream bug filed here - https://github.com/openzfs/zfs/issues/16261

Dear s390x porters,

I just ran into this bug. You might be of help. Upstream isn't able to
help due to lack of s390x access.


We don't run this test on Debian ci infrastructure as we use lxc and
this test has isolation-machine restrictions.

Paul

Hi Paul,

I will be happy to help.
I will mention this in the Github issue.

Thanks,
Pranav

Hi Paul,

I have a raised a PR (https://github.com/openzfs/zfs/pull/18445) for this issue.
I was able to successfully run all of the tests that were mentioned by the upstream
maintainers.

Thanks,
Pranav

Hi Paul,
