December 19, 20241 yr Good morning, I'm just starting to use unraid. I set up a NAS with: - Gigabyte Z590 Gaming X ATX Motherboard for Intel LGA 1200 CPUs https://www.amazon.fr/gp/product/B08XNKLGS4/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 - 64 GB of RAM - Intel I510400f - Card SAS9211-8I 8-port SATA + sas Pcie 2.0 6 GB memory card https://www.amazon.fr/gp/product/B002RL8I7M/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 - Power supply: Tecnoware 850W Modular Power Supply for PC Gaming - https://www.amazon.fr/gp/product/B08K964Y3J/ref=ppx_yo_dt_b_search_asin_image?ie=UTF8&psc=1 I have 9 hard drives of 10 TB so 2 for parity. But after each reboot or randomly I have I/O errors on the disks (all randomly). I tried to change the sata cables and power cables several times. I'm out of ideas. If you can help me, I will be grateful.
December 19, 20241 yr Community Expert The disks are not connected to the LSI, they are connected to a non-recommended controller with SATA port multipliers, do you also see issues if you connected them to the LSI instead.
December 19, 20241 yr Author yes, sorry. After the issues, i've connected some disk to this : https://www.amazon.fr/gp/product/B098QPJJFF/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1 For now, it's seems working for only 6 disk with two parity. Parity-Sync in progress is in progress.
December 19, 20241 yr Community Expert There are still ATA errors being logged for multiple disks, could be because of the SATA port multiplier or a power/connection issue.
December 19, 20241 yr Author Don't know, i've tried change alimentation and sata cable. I only have max 3 disk on one alimentation. Could it be because i have to use power cable extension as mine are too short for reach all disks ?

December 19, 20241 yr Author ok, i will try to remove alimentation extension and re-connect HDDs to the LSI and see if errors disappear.
December 19, 20241 yr Author Ok, i've remove all extension, max 3 disk on each alimentation cables, Disk connected to LSI with this cable : https://www.amazon.fr/gp/product/B07C13922C/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 and this https://www.amazon.fr/gp/product/B07BZCXM84/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1 and two directly to the mother board. tower-diagnostics-20241219-1643.zip
