I had two disks taken off from the three-disk raid set (hda,hdb,hdc - hdc failed by itself, hdb was marked bad with raidsetfaulty). When the new disks were added back to the set (with raidhotadd), only two of them became active and one remained as a hot spare. I there a way to reconfigure all three to become active again?
