Subject: [f2fs-dev] [Bug 216050] f2fs_gc occupies 100% cpu
Date: Tue, 13 Dec 2022 22:49:00 +0000 [thread overview]
Message-ID: <bug-216050-202145-K4O9oiZ5Lx@https.bugzilla.kernel.org/> (raw)
In-Reply-To: <bug-216050-202145@https.bugzilla.kernel.org/>
https://bugzilla.kernel.org/show_bug.cgi?id=216050
--- Comment #114 from Thomas (v10lator@myway.de) ---
(In reply to Guido from comment #113)
Why not test the "f2fs_io_schedule_timeout" kernel patch in combination with
running the manual GC script one time (doesn't seem to matter if you run this
on unpatched or patched kernel, all that's important is that you boot without
any garbage into the patched kernel, so reboot right after executing the
script) ?
I did this cause I readed between the lines that this combination worked for
others, too, and am having no more issues since around 5 days. And yes, I'm
doing a lot to try to trigger this bug again.
Also is it save to assume that this issue only occurs on root partitions which
are on NVMe drives? I see a pattern here but still not 100% sure.
