May 13, 20251 yr I have searched and tried some of the proposed fixes but I'm still getting a parity check every time I reboot my system. My last parity check yesterday finished without errors. Thank you. Logs attached. tun-diagnostics-20250513-1802.zip
May 13, 20251 yr Community Expert you can always cancel the parity check or, have you consider going parity-less and make 3 copies of everything: 1 Live + 1 on another server/disk + 1 offsite or online I prefer that approach to losing +60% of write speed on my HDs (<40MB/s vs >200MB/s)
May 14, 20251 yr Community Expert This is why: May 13 17:51:00 tun emhttpd: unclean shutdown detected You need to find out why it's not doing a clean shutdown, if you stop the array, does it stop normally?

There are many ways to lose data besides a disk-failure. Think of fire, theft, flooding, etc...
