I used to have control to do this via FreeNAS GUI but now trying to get ada6 to offline is bceoming a problem. The end to end errors are mounting and I want to swap the drive out with a new one. Could somone kindly outline the steps using the CLI to replace a faulty disk. I notice that the GUI has somewhat changed stopping me from using the replace functionality and the ability to offline the drive. I know it sounds so simple but a step procedure will help me. The Raid is healthy but the end to end errors are mounting and I have a new disk of same capacilty to replace and resiliver.
