veri745 Posted March 23, 2023 Share Posted March 23, 2023 A few weeks ago my array went into an error state, and one of the disks went red due to some filesystem corruption It's a relatively new disk, so I ran SMART diagnostics, ran the xfs_repair tool, ran memtest for several hours, and rebuilt the disk back onto itself Since then, I've had several occasions where disk read errors have cropped back up. It's always drives 2 and 4, they always have the same number of read errors, and so far it has resolved itself after a reboot. I am wondering if I experienced some data corruption as part of the initial issue, and the parity was someone incorrect and rebuilt the corrupt data back onto the drive. Attaching my diagnostics from before rebooting (ending 2045, no SMART for the two disks with read errors), and after (ending 2050) tower-diagnostics-20230322-2050.zip tower-diagnostics-20230322-2045.zip Quote Link to comment

Disks are dropping offline, this can be a power/connection problem, but since both are on a Marvell controller and these are known to sometimes drop disks without a reason first recommendation would be to replace that with a recommended controller.

Right, I meant that xfs_repair detected a filesystem error after the disk got disabled I had extra ports free on the motherboard, so I moved the two suspect disks to different ports. I will see if that resolves the issue over the next month or two and consider replacing my SATA controller card Thanks Edited March 23, 2023 by veri745 typo 1 Quote Link to comment
veri745 Posted March 23, 2023 Author Share Posted March 23, 2023 This card has an "approved" chipset, but seems really inexpensive. Decent option? https://www.amazon.com/Expansion-Controller-Adapter-Profile-Non-Raid/dp/B09KY3HB8Z/ref=sr_1_6?crid=D0AKVB0XY7UT Quote Link to comment
JorgeB Posted March 23, 2023 Share Posted March 23, 2023 Should be, it's always difficult to say for sure with these no name brands, sometimes build quality is not good, resulting in CRC errors or similar. Quote Link to comment
veri745 Posted April 6, 2023 Author Share Posted April 6, 2023 No issues so far after moving all drives off of the Marvell controller 1 Quote Link to comment
