Hi experts, I been reading about documentation about replacing degraded drives, because I have two and it is supported by hot spares saving the day. After reading two days of documentation I am still a bit confused because sadly I can not add a new drive due to budget.
https://www.truenas.com/docs/core/coretutorials/storage/disks/diskreplace/
With 7 spares available in place I am hoping to figure out how to use 2 drives available to replace the degraded drives and have state Online instead of Degraded. Do I just power off and unplug 2 selected available spares and replace the 2 degraded drive and resilver and the hot spares will go back to becoming available?
Thanks in advance for any help.
