Hi guys, got currently raid1 2x1tb drives (black and blue wd, old one) and just bought 4x4tb wd red plus. Now i wonder how i should make changes. End concept is 4x4tb raid5 or 6 maybe.
How to start? I am not sure if i can do this:
1. Use 2 new 4tb drives, on one of them copy existing data from existing 1tb raid, to make a copy, and take this disk out of nas after this. If i use it later, it should be seen properly by the same nas? And after making backup of existing data (just copy between storage pools?, 1tbx2 disks, currently used, and one single disk as another pool?) is there any better way than just copying it? Maybe some tool - what i want is to have possibility to use the same single disk later if smth bad happen and copy back this data to new raid eventually created from scratch on new 4tb drives in raid5.
2. if i can have this backup, i still got 2x1tb disks as raid 1 in bay1 and bay2 together with data, and in 3rd bay - new 4tb disk. So now i extend this raid1 with bay3 disk. Why this way, first new disk and raid5 - cause i still got existing data in nas, and backup on 4rd disk.
3. After this i should have bigger raid5 pool on 3 disks, 2x1tb and 4tb. Than i swap first 1x1tb disk with next 4tb disk.
4. Last step is to swap last 1tb disk with 4tb disk - i got 3x4tb raid5 and 4th drive with backup. If all is ok, i add this backup drive and add it to raid5 - than i can migrate? to raid 6 eventually?
is this correct?
Other way is to make backup, change first drive of 1tb raid1 and add 4tb one, than, change second drive to 4tb and than add new 3 and 4 drives and go raid5.
5. How hotswap works? Can i plug and unplug drives while nas is working? Should be any other steps of manually disable disks etc be done before? Or should i turn off nas and than unplug drive?
6. What kind of ram can i use - does 8gb one provide dual ram with 4gb in nas? Or is should be 4gb one? Do i loose warranty using unofficial ram?
Thank You for help.
