Wrong Pool State box_3_sas - replacement device too small

Hi,

I am trying to change to a larger disk, but I got that error. This does not make sense to me.

Basically, I am trying to swap one of the 900G to a 1.8T drive, but not working. Btw these 2TB ones and 900GB ones are under different vdevs. Seems Unraid is expecting 2TB drives, which is not necessary.

A temporary solution is:
You can replace the drive with

zpool replace you_tank_name /dev/sd* /dev/sd*

After resilvering, stop the array, unassign all drives from the pool, click the pool name, and delete the pool. Then add a new pool and assign all the drives back.
