[Pkg-zfsonlinux-devel] [zfsutils-linux 2.0.1-3] ZTS Results for Linux 5.10.0-2

[Antonio Russo]

I've been running the ZTS regularly as new versions of ZFS and the kernel
have been entering sid.  Until -3, however, the runs were not clean enough
to provide much useful feedback.  With -3, several patches are now included
and I can get (mostly) clean ZTS runs.  If people are interested, I can
continuing post these reports here.

Here's the most recent report:

Debian Kernel Version: 5.10.0-2-cloud-amd64
Debian ZFS Version: 2.0.1-3

# Analysis #
############

Re-running the zpool_events_duplicates test failed a second time. But
attempting to bisect down to a minimal reproducer has failed; all
subsequent attempts to reproduce have failed.

The failure seems innocuous: it is just a single duplicated zpool event
reported. I have not been able to reproduce this on local bare metal (the
ZTS run was performed on a relatively flaky cloud hosting provider's VM),
so I suspect there may be some unlikely race that would only be triggered
on overburdened hardware.

Best,
Antonio
