ReadyNAS 316 Switched to Flex-Raid

[Rossconocash]

Hi,

I have 6x 4tb drives that were set up as X-Raid. I switched it to Flex-Raid when I was trying to work out how to encrypt it so my PC backups would be secure.

Now I have 3 raid groups (group #1, #2, #3).

Group 1 and 2 both seem to be using all 6 drives whilst group 3 is using drives 1, 2, 3, 5, and 6. They all show the same amount of data, spare space, and snapshots.

I want to switch back to X-Raid, but don't want to lose my data.

Can I just destroy groups 2 and 3? Or will this result in data loss?

Sorry I am not super experienced with all this.

Thanks in advance 🙂

Don't destroy them, you will lose your data if you do that.

You must have started with smaller disks - the NAS creates these RAID groups when you vertically expand the array.  They are all concatenated into your volume, so if you destroy any of them the entire volume will be lost.

Have you tried doing that? Just click on the X-RAID control on the right.  

If it won't let you, then you'll need to stick with FlexRAID (or do a factory default).

Something sounds wrong on this part.  After you try switching to X-RAID, perhaps download the log file.  Post partitions.log and mdstat.log here.
