Expanding Disk Space on raid 10
firmware 6.5.0 readynas 2120 I’m use 4---2TB drives with raid 10, total storage 4TB. I want to add more storage. I’ll either switch to raid 5 or get larger drives and stay with raid 10. I only h...
RAID6 on 4 HDDs with ARM CPU is going to be slower than RAID5. Imo, the difference of performance between RAID5 and RAID10 is not going to make any significant difference in your case. Unless you'll never use the capacity it would give you with the HDDs you have, I would pick RAID5.
By nature, all the HDDs in a RAID10 must be the size. Or at least, the system will use the biggest common size (which is set by the smallest HDD).
There is a trick with mdadm to find which HDDs belong to which vdev/pair (cf Google), but it's not the easiest, and replacing several HDDs at a time is looking for trouble. So unless you have a 12 HDDs RAID10, I advise you to upgrade the HDDs one by one. Also because of the nature of RAID10, resync times aren't that long.
I will try reinstall the disks 1 at the time.
Still not sure if I should stick with raid 10 or switch to raid 5 or 6.
