In an effort to test and prepare patches from XFS to stable 6.1.y [1], I needed
to make a baseline for v6.1.53 to verify that the backported patches do not
introduce regressions (if any). However, after a 'make fstests-baseline', we
observed that compared to v6.1.42, v6.1.53 introduced more than expected
expunges to XFS. This RFC is an attempt to put some eyes to this and open up a
discussion.
At Cloudflare, the Linux team does not have an easy way to obtain dedicated and
easily configurable server infrastructure to execute kdevops filesystem testing,
but we do have an easily-configurable kubernetes infrastructure. I prepared a
POC to spin up virtual machines [2] in kubernetes to emulate what terraform
may do for OpenStack, Azure, AWS, etc... to perform this test. Therefore, the
configuration option is set to SKIP_BRINGUP=y
In this baseline, I spun up XFS workflow nodes for:
- xfs_crc
- xfs_logdev
- xfs_nocrc
- xfs_nocrc_512
- xfs_reflink
- xfs_reflink_1024
- xfs_reflink_normapbt
- xfs_rtdev
Each node is running a vanilla-stable 6.1.y (6.1.53), and the image is based on
latest Debian SID [3]. Each node also has its own dedicated /data and /media
partitions to store Linux, fstests, etc... and sparse-images respectfully.
In v6.1.42, we don't currently have expunges for xfs_reflink_normapbt, and
xfs_reflink. So those are _new_. The rest had significant additions. However,
not all nodes finished their testing after >12hrs of run time. Some appeared to
be stuck, in particular xfs_rtdev, and never finished (reason unknown).
I CTRL+C and ran 'make fstests-results'.
I prepared a fork [4] where the results 6.1.53.xz can be found.
These patches are based on top of commit 0ec98182f4a9 ("bootlinux/fstests:
remove odd hplip user")
