August 25, 2025Aug 25 My Unraid v7.1.4 runs a parity check every time it is restarted. Why I need to restart will be another post but for this I am wondering is this due to a setting, an internal decision by the OS, or something else? In versions prior to v7 this did not happen.Diagnostics attached in case that helps provide more insight to the cause of running parity check upon restart. nasmedia-diagnostics-20250825-0646.zip
August 25, 2025Aug 25 Community Expert Solution Many times, this condition is caused by a process having a one or more files open and not releasing the file. To test for this, have the array running and 'STOP" the array using the button on the MAIN tab. Time how long it takes the array to stop. There is a timer ("Shutdown time-out (seconds):") under 'Disk Settings' on the SETTINGS tab after which the array forced into shutting down. This will always result in an unclean shutdown and parity check on restart. If the array fails to stop you will have to figure what is holding the file open. (Docker containers are always a good starting point...)
