due to a broken sata cable one of my raid 1 drives went missing and the raid went to "degraded, clean". I replaced the sata cable and the missing hdd was back again. Now i want to add the missing drive to the raid again. I have done that multiple times so thats no problem for me.
BUT the raid is under constant use from several systems to store data. The 2 hdds are about 4Tb so it takes a while to rebuild the raid. So i was wondering if i can keep using the raid while it is rebuilding. Whats happening with new written data during the rebuild process? Or do i have to block the access to the raid and rebuild it?
Thanks for your help
