December 22, 20214 yr Hi Guys Woke up with some warnings and disk9 has now been disabled, first warning was disk with read errors, followed by disk in error state. Dec 22 02:02:43 Server kernel: md: disk9 read error, sector=19536969840 Dec 22 02:02:43 Server kernel: md: disk9 read error, sector=19536969968 Dec 22 02:02:43 Server kernel: md: disk9 read error, sector=19536970088 Dec 22 02:02:43 Server kernel: md: disk9 read error, sector=19536970224 Dec 22 02:02:43 Server kernel: md: disk9 read error, sector=19536970344 Dec 22 02:02:44 Server emhttpd: read SMART /dev/sde Dec 22 02:02:44 Server emhttpd: read SMART /dev/sdn Dec 22 02:02:53 Server kernel: md: disk9 write error, sector=19536969840 Dec 22 02:02:53 Server kernel: md: disk9 write error, sector=19536969968 Dec 22 02:02:53 Server kernel: md: disk9 write error, sector=19536970088 Dec 22 02:02:53 Server kernel: md: disk9 write error, sector=19536970224 Dec 22 02:02:53 Server kernel: md: disk9 write error, sector=19536970344 Unable to run SMART but have attached diagnostics, before I do anything else, would appreciate some advice. I am hoping it's something like bad connection or something as its a 12TB drive! Thanks in advance! server-diagnostics-20211222-1039.zip
December 22, 20214 yr Author Shutdown, checked all drive bays and connections seem fine. However on starting back up I got the following message: Unraid array errors: 22-12-2021 11:44 Notice [] - array turned good Array has 0 disks with read errors Disk9 is still disabled so I am going to leave everything as is for now. Disabled docker and vms just in case too.

December 22, 20214 yr Community Expert Disk dropped offline, could be power/cable related, could also be spin down/up related, since it happened on spin up, SMART looks fine, if the emulated disk is mounting and contents look correct you can rebuild on top.
