ReadyNAS Ultra 6 Plus.... 18TB -> 24TB

Have you tested the bad disks using SeaTools? Run both short/quick and extended/long tests. What RAID mode are you currently using? If using X-RAID2 are you using single-redundancy or dual-redundancy? What is the current volume capacity? What disks were installed when you last did a factory reset.

Thanks for quick reply :)

Hi, yes, when disks went bad, one was replaced by Seagate, other out-of-warrant period :(
When I find time I will test that bad one with Seatools.

I'm currently using X-RAID2 with dual-redundancy. I cut&paste volume:
Volume C: Online, X-RAID2, 6 disks, 81% of 13 TB used

These 3TB disks were installed at the time of purchase so initially volume was configured as it is now. No expansion was ever done.

I'm running out of space and need extra space that's why I wish to use 4TB disks.
But the question is can I do this in this painless way of "pulling old 3TB/inserting new 4TB/wait-for-syncing" drives one-by-one"

Thanks!
