How can you tell on what disk it happens? I have two nvme - one "plain" f2fs root, another is f2fs on dm-crypt - that's home, where a lot of compilation happens. >From logs and stats I cannot tell where f2fs GC problem occurs. What should I look for? If I would know problematic disk, I would increase load on that disk. Second question: /sys/fs/f2fs atgc_age_threshold has 604800 value. That's 1 week. Changing it to one day or 4 hours - will it really help to trigger problem? If it will, it would be a "safe" way. Thanks again. -- You may reply to this email to add a comment.
