software raid - add device wrongly marked faulty back into array?
Anyone know how to add a device back to a raid array that has been marked faulty wrongly. I had one faulty disk in a 5 disk raid 5 array. I removed the wrong disk (!!) leaving me with just three active.
The array is meant to be
/dev/hdg7, /dev/hd[abcd]1
hdd1 failed, but I removed hdc1 (silly), leaving me with 3 disks, which of course is one too few, and the array won't start.
adding the hdc1 and hdd1 back again resulted in the config below.
How do I put hdc1 back as an active component of the array, without loosing the data?
/dev/hdc1:
