Thanks @Peter Debik and @hschramm . I understand your explanation. Yes, it seems that rsync process is affecting.However, It's closed for 2 days and something still increases the I/O. I sent you last nights monitoring.
I talked to Hetzner and they say that there isn't any backup or check on...
I move all data to another server. It happens when resyn is closed too.
I have seen md2 raid 5, md3 raid 5 processes. I think it checks disks as there are software raid. We tried to close it but it still continues.
Hello, I have a weird problem. My server's disk usage increases by 75%-100% at the same time every day. Meanwhile, freezing and slow loading problems occur on the server. Since I broadcast videos via the server, loading and buffering problems occur due to this problem.
There is no cron or backup...
