Correct - I worked with 45Drives to get a replacement. I sent my cables back to them so they could check them out. I followed up once via email but never did hear a resolution. Just given the amount of time, I’m guessing only a few of us were unlucky enough to get cables out of tolerance enough to give us issues.
I’m guessing you may be running SATA drives so this thread may not be as applicable as it would otherwise be. In the default configuration, only 7 out of the 15 slots (9-15) are using the motherboard SAS controller. SATA runs at 6gpbs so, if you do have a cable issue, it’s probably even more out of tolerance than the ones I received last year. It’s possible as manufacture defects do happen but seems unlikely in my opinion.
@mango - if you do want to try to slow down the link speed to see if that helps, here is a guide I wrote to do that on the SAS controller. You should be able to take it down all the way to 3gps. You’d also have to move your drives to slots 9-15 for this to work or physically switch the SAS cables to be slots 1-8 and the SATA controller to 9-15.
You can also clear the checksum errors via zpool clear POOLNAME. I think it’s also good practice to do a second scrub after finding ZFS errors.
