Expanding Disk Space on raid 10

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 have 1 volume on the nas. I was hoping to vertically expand the volume, but I don’t think you can do a vertical expansion with raid 10 in the readynas line……maybe you can in the readydata?

No - you can't expand RAID-10.

My 1st step would be getting all the data off the current drives. There is roughly about 1TB snapshots on the current drives, I want to keep those snapshots. Will the snapshots come with the data if a I do a full backup of the nas?

They will not be kept.  You could format a USB drive as BTRFS, and then you could preserve the snapshots by copying the volume with ssh. (btfrs send | btrfs receive)

Also, once I have a copy of the data, I should be able to delete the current volume and load new disk, correct? I won’t need to start over with all my nas settings will I

 

 

I'd save the NAS configuration (system->settings) anyway.

But you should be able to destroy the data volume, and replace the disks one by one.  Uninstall any apps first.  The NAS will need to resync the OS partition as you do this.  When you are done, recreate the RAID-10 volume and reinstall any apps.
