[6.9.2] Parity checking scheduling not working in Stable Releases Posted January 1 · Edited January 1 by altyne 42 minutes ago, Squid said: Yes @Squid I know the reason. Just now we have experience a brownout; it happens only a few seconds. Just now parity checking is running. During that time around 08:22:21AM , I didn't know we have a power outage and I was sleeping. Thanks to all. I need to protect my server with UPS since occasionally brownout occurs in my place.
