I guess at this point, I’m going to need something stronger than coffee:
I’m going to bed now, so I’ll see where we are in the am.

Early in scrubs & resilvers the ETA is usually way, way off. But, yours seems to be a record. Congratulations!
But, you should probably clarify what is resilvering. For example, these have been known to be much slower than normal:
- SMR hard disks
- Excessively wide RAID-Zx stripes, like 20 disks in a single vDev
- USB attached multiple disks, (worse if they are all on one USB bus)
Only the last could be completely fixed by moving the disks to real disk ports.
The SMR has some partial fixes, depending on specific layout. Meaning if the replacement disk is SMR, stopping and using a CMR disk would help. (Though any other SMR disks not yet replaced can still slow the process down.)

Do you want speed or do you want accuracy?
You may only choose one.

It was the second step on updating a special vdev from 2 x 1T NVMe SSD to 3 x 2T. I had already introduced a 2T as the 3rd SSD and that step was complete.
This was replacing one of the 1T SSD with a 2T:

The main pool is a 6 x18T (all CMR) raidz2.
And obviously it didn’t take 9000 years, as it was finished this morning.
Cheers.
