September 23, 20223 yr Hello, my unraid server was performing a parity sync/rebuild (switch from single to dual parity) and finished at 4:24 this morning. Shortly after 1 disc (disc4) was disabled within unraid. After discovering this error i've checked everything and stopped the array, removed the disc, started array, stopped array, reassigned the disc and started the array with rebuild. shortly after disc2 was disabled too. currently rebuild of disc4 is still running and disc2 is still disabled(will be rebuild after disc4 returns normal operation). Can someone tell me what happened here? Currently i'm hoping the rebuild will finish without error and i wont lose any data. Diags attached! My server is a Ryzen 5600G based system, Asus b450 gaming-f motherboard, LSI SAS2308 IT-Mode, 6x Toshiba N300 8TB HDD, 4 ssds for 2 cache pools. Thanks alot. tower-diagnostics-20220923-0638.zip
September 23, 20223 yr Community Expert Solution Disk dropped offline, looks more like a power/connection problem.
