Hi, I'm hitting a reproducible transaction abort with -EAGAIN on a
host-managed SMR drive. The filesystem is forced read-only during
plain sequential writes. Hardware: - WDC WSH722626ALN607 (Ultrastar DC
HC670 26TB, SATA, host-managed) - connected directly to onboard SATA
(Intel X99 AHCI), 6 Gbps - drive reports write cache disabled, no
DPO/FUA support Software: - Kernel: 7.2.11-200.nobara.fc44.x86_64
(Nobara/Fedora based, tainted by Nvidia out-of-tree modules) -

Hi Jochen,
I made a couple of fixes for -EAGAIN returns on zoned FSes that landed
in 7.3. Can you check 7.3? There's two possibilities that might bite you
here. One is a hole in the metadata write stream and one is a transient
relocation error. Both will bubble up as -EAGAIN without these fixes.
Thanks a lot,
Johannes

Hi Johannes,
no problem, hope you had a good vacation!
Dropping the list was not on purpose, sorry about that - re-added
it. Happy to stay in English here for the archive.
The full 'blkzone report /dev/sda' output is ~191k lines, so I've
sent it to you off-list as an xz-compressed attachment.
The fs is currently mounted read-only via fstab, untouched since
the last abort. I'll leave it like that until you tell me
otherwise.
Thanks,
Jochen

Hi Johannes,
small update: my distro has meanwhile shipped a new kernel,
I'm now running 7.3.1-202.nobara.fc44.x86_64 .
I haven't tested with it yet, the fs is still mounted read-only
via fstab. Should I try a read-write mount with the new kernel,
or do you want the on-disk state left untouched until you've
looked at the zone report?
Thanks,
Jochen

Hi Johannes,
sure, I'll leave it untouched.
I had sent you the full report off-list as an .xz attachment,
I suspect it got caught by a mail filter. Here's the condensed
version instead.
Zone state summary:
1918 zcond: 0(nw)
30387 zcond:14(fu)
159343 zcond: 1(em)
128 zcond: 4(cl)
All zones that are neither empty, full nor conventional
(line number = zone index + 1):

The full report (191776 lines, 24 MB uncompressed) is available
if you need it - just tell me how you'd prefer to receive it.
Thanks,

Thanks. I'm a bit puzzled why we have CLOSED zones, I was under the
impression that a FINISH set's the zone to FULL not CLOSED. I'll have to
re-read SCSI ZBC for answer to this.
This is different from your problem (which is holes in the metadata
write stream). If you could upload the full report somewhere that would
be great. Also if you still have the full dmesg that would be awesome as
well.
Thanks,
Johannes

Hi Jochen,
Maybe this patch series could help:
https://lore.kernel.org/linux-btrfs/cover.1787887776.git.zhudongjiang@fygo.io/
Would you be willing to give it a try?
Thanks,
Dongjiang

Hi Dongjiang,
thanks for reaching out - yes, I'm willing to give it a try.
Johannes asked me to keep the on-disk state untouched while he
looks at the zone report, so I'd like to coordinate with him
first: Johannes, are you fine with me testing Dongjiang's series
on this fs, or do you need anything else from the current state
before I do?
For testing I can set up a separate machine (bare metal, no
out-of-tree modules), so my main system isn't affected and
switching kernels is easy. I'd move the drive over there.
Two practical questions, since I've never built a patched kernel
for testing:
- Which base should I apply the series to (e.g. 7.3, or a
specific btrfs branch)?
- Is there a git branch with the series applied that I could
use instead?
Thanks,
Jochen

Yeah if you don't mind, give it a shot.

Base: in sync with btrfs/linux's for-next branch as of today:
https://github.com/pdzhu/btrfs-linux/tree/for-next
Testing branch: my v3 series rebased onto that base:

Thanks,
Dongjiang

I think I could re-create the issue and unfortunately Dongjiang's patch didn't
fix it for me (I've only applied patch 2 not the whole branch). What fixes it
for me is:
diff --git a/fs/btrfs/zoned.c b/fs/btrfs/zoned.c

Hi Johannes,
great news that you could reproduce it - thanks a lot!
My test machine needs a couple of days to get ready (new SSD and
thermal paste on the way), so no rush on my side. When it's
ready, which tree should I apply your fix to - Dongjiang's
for-next base, or plain 7.3? Or will you post it as a proper
patch / push it to a branch I could use?
Thanks,
Jochen

I think it should apply to all but I can push a branch for you if you
want. I'll send a proper patch and testcase for it ASAP as well.

Hi Johannes,
yes please, a branch would be great - that's the easiest way for
me. I'll test as soon as my test machine is ready and report back.
Thanks,
Jochen
