I have a RAID6 consisting of five 1TB drives and it works fine. I want to redistribute the array in different ways in my system (change the drive allocation through the controller card). I I pulled the first drive where I wanted it; now I only have one drive left. Since it is RAID6, it should have dual drive redundancy; will this extend the time during resynchronization? Can I pull the second drive even though the array still resynchronizes to the first moved drive? If so, can I restart resynchronization on two moving drives at the same time?
For RAID6 arrays, you must be able to do this, you just push the array to handle the second drive failure, which This is the purpose of RAID 6.
I will not do this on a production system. The main reason for choosing RAID 6 is that you are concerned about a single (additional) drive failure or a single read failure during the reconstruction process. The possibility is paranoid. By performing a RAID6 dual drive failure situation, you will put the array in a situation where a true single drive failure or a read failure will cause it to terminate. This will be a risk, I would rather not take the array, I think it is necessary first RAID 6. If the performance loss during the reconstruction process did not cause you to die, I suggest letting the first resynchronization complete, and then moving the second drive so that your system is always protected.
