April 4, 201115 yr After 3 of my disks went dead (See my previous post "3 Disk failure") I now have 4 new, precleared, disks. The 4th is to upgrade my parity to 2T. I still have 3 good disks from my old setup and I want to make sure I rebuild the parity without losing the data on them. Is this the correct procedure? 1- All drives were unassigned previously. 2- New disks precleared with preclear_disk.sh 3- Reassign the 3 good disks to the same slots they were in before (Do I have to use the same slots?) 4- Assign the new disks to free slots 5- run inticonfig 6- Restart the array Is this correct?

You are basically starting over. There is no "rebuilding" with multiple disk failures. Just run initiconfig, arrange your disks, and start the array. unRAID will build parity. The fact that you precleared your disks is good, because it gave them a good workout prior to trusting them with data. But the fact that they are precleared doesn't reduce the time to do the initial parity build. Make sure to assign the parity disk to the parity slot. Assigning a data disk to the parity slot will cause you to lose the data on that disk.
April 4, 201115 yr Just run initiconfig, arrange your disks, and start the array. You have to arrange and then initconfig. Assign the disks how you want ensuring the parity is correct. Then, do the initconfig and start the array. You can start without the parity first if you're not 100% sure you have the right disk for the parity. Peter
