Aren’t you supposed to be able to keep your server operating during a raid 5 single disk failure? My server mounted the raid array as read only and when I force remounted it as read/write my proxmox VM now hangs on boot (presumably due to the degraded raid array).

The rebuild process is going to take 20 hours. Shouldn’t I be able to continue to run my server as normal during the rebuild? Do I have to do anything to mark the array as healthy?
