Hello,
While running LTP [1] as part of CKI [2] testing, we noticed the fs_fill
test fails pretty
consistently with BTRFS warnings seen below, this is seen with recent
kernel (5.2.12).
I have included the logs below for reference.
I'm only 6 for 6, but so far can't get it to trigger with 5.3.0-rc7
Also cannot reproduce, 10 for 10 with 5.2.13-200.fc30.x86_64 which was
just built in koji, same as 5.2.12 which was quickly replaced with a
single unrelated revert for touchpads.
But comparing fs_fill logs, yours has a ton more writer threads (~6x)
and ENOSPC counts. Possibly related?
It could be related to the higher thread/ENOSPC counts, I tried to
manually reproduce
right now and was unsuccessful, I'll see if I can get a reproducible
scenario. I'm traveling
the next few weeks but will review results when I get back.
Thanks for looking into it!
Rachel
