FreeBSD 13 has problems with the virtio nic. Just use the e1000 nic, like I gave done it here: https://github.com/mcmilk/zfs/tree/qemu-machines2

Ah, some other problem :(

@tonyhutter tonyhutter force-pushed the qemu2 branch 3 times, most recently from 136cf60 to 73f5c57 Compare June 25, 2024 20:42

The timezone "US/Mountain" isn't supported on newer linux versions.
Using the correct timezone "America/Denver" like it's done in FreeBSD
will fix this. Older Linux distros should behave also okay with this.

@mcmilk the zpool_status_008_pos failures are just timing. This fixes it:

I'm still trying to figure out why raidz_expand_001_pos.ksh is reporting errors. That seems to be the last test that is failing on QEMU.

This commit adds functional tests for these systems:
- AlmaLinux 8, AlmaLinux 9
- ArchLinux
- CentOS Stream 9
- Fedora 39, Fedora 40
- Debian 11, Debian 12
- FreeBSD 13, FreeBSD 14, FreeBSD 15
- Ubuntu 20.04, Ubuntu 22.04, Ubuntu 24.04

Workflow for each operating system:
- install QEMU on the github runner
- download current cloud image
- start and init that image via cloud-init
- install deps and poweroff system
- start system and build openzfs and then poweroff again
- clone the system and start qemu workers for parallel testings
- do the functional testings, hopefully < 3h

The error comes from the command zpool scrub -w testpool within the ksh function test_scrub:

SUCCESS: zpool import -o cachefile=none -d /var/tmp testpool
SUCCESS: zpool scrub -w testpool
SUCCESS: zpool clear testpool

I think. the scrub -w wants start scrubbing on a pool, which does this already.

Option 1: check the status first, and if already some a scrub started, than just wait for it
Option 2: always stop scrubbing via zpool scrub -s and ignore the exit status of it

What would you prefer?

I think that might help some of the raidz_expand_001_pos failures, but not eliminate it completely. There may actually be a legitimate problem that's just being exposed but I'm not sure yet. I want to get some more test runs done to see.

Also, I tweaked my commit a little to add more time in zpool_status_008_pos and fix a rare timing bug in crtime_001_pos.

I will test run this with a for loop, I think 50 times should be a good start.
Only these two via -t raidz_expand_001_pos + -t raidz_expand_002_pos

It's running with -I 55 option:

Hm, the raidz_expand_001_pos tests are failing, even if the wait for scrub thing :(

I used this is_pool_scrubbing $pool && wait_scrubbed $pool

Almalinux 8 and Ubuntu 20.04 are fine.
Maybe it's bclone related - cause this is disabled on the older kernels?

Some points to the raidz_expand_001_pos testing problem:

  • I limited the code to run only on scalar speed (exclude possible assembly failures)
  • FreeBSD 13/14 does not have this issue et all, all tests run fine at around 2m 30s
  • FreeBSD 15 does not have this issue et all, all tests run fine at around 4m
  • on Linux 5.4: timings are around 3m and the faling test rate is: 1/120
  • on Linux 6.x: timings are around 5m 30s and the faling test rate is: 1/2 maybe 1/3

Special test run with only raidz_expand_001_pos: https://github.com/mcmilk/zfs/actions/runs/10346648527

So the raid code is maybe okay... but some spl thing?
Should we run against zfs-2.2.5 ??
