I have a MyCloud EX2 set up with RAID1 where one of the drives failed. I replaced the drive with a new one, but the “auto rebuild” option doesn’t seem to have ever kicked in. The drive is recognized and tests as “good” with no errors. Same with the other existing drive. If I turn off the automatic RAID rebuild switch, the “manual” button doesn’t show up, even after a reboot. I can see it’s there in dev tools, just hidden. I’ve tried un-hiding it and clicking, and it takes me through the menus, but still doesn’t start the rebuild. After getting through some jquery errors, the SSH switch started working, so I turned that on, but I’m not sure if there’s a way for me to start that rebuild via SSH maybe? Anyone else see the same issue?
