Update on this.. turns out the "new" drive (actually not-so-new) was no good. Put in a different one, and it's currently syncing at ~30MB/sec
Thanks for the help
Thanks.. don't know how I didn't notice it was set that way. I just changed it to AHCI though, and the sync performance is the same.
Going to check again that the cables are good, etc and will report back.
I had a 2TB drive that was reporting errors, so I replaced it with another 2TB, but the parity sync is now going extremely slowly, ~250 KB/sec..
I looked through the syslog and didn't see anything that jumped out at me.. diagnostics are attached. Any ideas greatly appreciated.
