Good day, I was wondering if there is any way to assign the same spare disk to multiple software RAID arrays. With hardware controllers you can assign a disk as a "global hot spare." When any disk connected to the controller goes south (no matter which array it is in), the global spare disk picks up the slack. If there is no way to do this with raidtools, could I possibly use mdadm to monitor for a failure and then hotadd a disk that is not part of any array? Thanks for your help. Regards, Andy.
