November 30, 20241 yr I currently want to upgrade 2 of my drives to larger 12tb (parity and data drive). Instead of replacing one drive at a time and letting parity rebuild twice, would it be safe to replace 2 drives at the same time because I have 2 parity drives? Current Array: 1. 4TB Parity1 -> upgrade to 12tb 2. 12TB Parity2 3. 4TB data1 4. 4TB data2 5. 4TB data3 6. 2TB data4 7. 2TB data5 -> upgrade to 12tb
