Ultra 6 - New drives will not format

I have a ReadyNAS Ultra 6 with 4 drives in one RaidX of 4 4TB drives that is running out of free space. So I want to add 2 3TB drives to fill out the 6 slots. I have physically inserted 2 drives into...

Hello greymont1,

Adding new disks to an existing XRAID of 2 or more disks should be done one disk at a time. Can you still access the files without the new disks you have inserted? Do you have full backup of the data?

You might want to read this article: How do I horizontally expand an X-RAID 2 volume on my ReadyNAS OS 6 storage system?

Also, please check HCL when deciding to add disks for volume expansion.

These new disks should not have partitions.

Thanks for responding, JennC.

I can still access the data and I'm in the process of making a complete backup. (This unit as actually the backup of another ReadYNAS unit, so making a backup of it is somewhat redundant, but nevertheless important.)

I tried adding the disks individually. I only added the second disk to see if the priginal problem was specific to the first disk. The disks are on the HCL list. The disks do not have any existing partitions. I just initialized them but did not create any partitions yet.

I'm still stumped.

  Hello greymont1,
  
  Best way here is have a full back up, once done, insert all disks you want to use with the NAS then factory reset. In this way, NAS will format all the disks to it file system format then it will allow you to select if XRAID or FlexRAID and create volume.

    Yeah, that's pretty much where we got when thinking it through.Luckily we planned for complete duplication of everything so we can take the factory reset route without much risk.
    
    Yes, it IS legacy hardware that is no longer supported and, yes, this unit was never suposed to run OS6 anyway, but still it is annoying that there is no way to peek into what is happening and see why the single drive formatting is just failing with no logging at all.
