Ultra 6 Replacement Drive Not Syncing
I've been running a ReadyNAS Ultra 6 Plus (latest official firmware) for some six years (and an NV+ for years before that), so when I got messages that one of the six 2-TByte drives (Seagate ST2000DL...

You could try removing the disk, and deleting the partitions on a PC. Then reinsert the unformatted disk.

Thanks. I knew that drives which already are partitioned may not be promptly recognized. It is for that reason that I deleted all partitions on the PC before returning it to the ReadyNAS. Also, if I interpret the sgdisk output correctly, ReadyNAS does not see any pre-existing partitions on the replacement drive (/dev/sdb) either.

For lack of any guidance, I zapped the partition table on the new drive (sgdisk -Z /dev/sdb) and rebooted. On boot, the front panel indicated "testing disk 2" for a few minutes, followed by "disk 2 passed" But I can see now indication that the sync is actually taking place. Is there any log/etc I can look at using ssh that would give me some clue about what, if anything, is happening. All the relevant lines from /var/log/syslog were in the original post.

There is an expansion log (expand_md.log in /var/log/frontview).
If you hover your mouse of the disk "ball" icons in frontview or RAIDar, you also get some status.
