August 15, 20232 yr Hi guys, suddenly I am facing an issue with Disk7. It is marked as ""Device is disabled, contents emulated". Fortunately, as it was the last disk of the array, there was no data on the disk yet. I run a self build Unraid server with mainboard an two SATA cards in it. Did I made any changes? Yes, I added two SSD to create a cache pool. Those were connected to the same controller. But first everything went fine. 1 or 2 weeks later Disk7 stopped working. What I did to fix the issue? Checked if the drive spins up when connecting power to it -> yes I tried the same drive on another controller + on mainboard sata port (a port which works for another drive) with several shutdown/restarts inbetween -> no change Tried 3 different sata cables -> no change I connected the drive under windows, drive is available, I deleted the volume, installed again in the Unraid server, I got an option for formatting the drive in Unraid, did the format but still, if I add it in the stopped array, still the red cross for "device is disabled". In the meantime I bought a LSI SAS9211-8i Controller to replace my two controllers in the next days as I do not fully trust them. But on the other hand drive was also not working on a sata port of the mainboard where another drive runs fine. Hope you guys can help me solve this. Attached the diagnostics. Thanks in advance tower-diagnostics-20230815-1024.zip Edited August 15, 20232 yr by Jules0815
August 15, 20232 yr Community Expert We can't see what happened because the diags are after rebooting but once a disk gets disable it must be rebuilt: https://docs.unraid.net/unraid-os/manual/storage-management#rebuilding-a-drive-onto-itself
August 15, 20232 yr Author I followed the steps, looks better now, rebuild progress is running. I will let you know when it is finished if everything worked. Thanks
August 16, 20232 yr Author I was too optimistic ... After writing data to the drive again, it stopped working. Diagnostics attached, no reeboot done. Thanks in advance tower-diagnostics-20230816-1927.zip
August 16, 20232 yr Community Expert Solution Disk dropped offline, it's on a Marvell controller, those are known to sometimes drop devices with no reason, suggest replacing it if possible.
August 16, 20232 yr Author Ok. I got a LSI 9211-8i which I will set to IT-mode. Waiting just for cables and give it a try with that one. Thanks
August 30, 20232 yr Author After two hours because of the PAL error I managed to flash the LSI 9211 to IT-mode via EFI. ... Data rebuild is running, will let you know if it works fine in the next days/weeks.
