Error when extending pool

[BlueJ007]

I have a pool with 2 x RAIDZ2 vdevs, each with 6 drives, and I am attempting to add another 6 drive RAIDZ2 vdev, but I'm receiving the following error: "Command '('dd', 'if=/dev/zero', 'of=/dev/ada2p2', 'bs=1m', 'count=32')' returned non-zero exit status 1." Anyone ideas what to check?

Also, here are the details from the More info section:

This part is telling you that an attempt to write 32MB worth of zeroes to ada2 didn't work.

You should check if there's an issue with ada2 and/or the cabling to it.

I guess one of the SATA cables was barely loose despite having locking clips and showing under Disks. I disconnected and reconnected the cable and all is working now. Thanks!
