Hello steveoelliott,

I see. It should still be one at a time, same procedure with expansion. Replace one, let it resync and once done, replace the next disk and so on and so forth.

This might help: How do I replace a disk in my ReadyNAS Ultra, Ultra Plus, NVX or Pro series storage system?

Hello steveoelliott,

We always strongly recommend to have full backup of important data.

Volume expansion may take a day for each disk, depending on how large the volume is. You may visit How do I vertically expand an X-RAID 2 volume on my ReadyNAS OS 6 storage system? article.

Hi,

I will be using identical drives for replacement so there should not be any expansion... Just a re-sync.

I presume this should be faster...

Thanks...

  All - Just so I have an idea of the time involved, how long ball park would an X-RAID 2 rebuild take on a pro 6 after I swap one of the disks? I will do this one at a time.
  
  I have 4x1TB in an X-RAID2 dual redundancy and am looking to proactively swap two of them so mechanically the disks are different from a wear perspective. I have exactly the same models since I kept some back when the installation was initially completed.

    I'm thinking at most 3 hours per 1 TB disk. I've seen a log posted some time ago that showed about 7 hours to resync 6x2TB RAID-6. That's 3x the disk I/O that is needed for 4x1TB RAID-6.
