Hi Guys,

 

When I set up Unreal Unraid I had 3 NVMe SSD's and 6 mechanical drives. I assumed the SSD's would be allocated into slots 1,2 and 3 and the mechanical into 4,5,6,7 and 8. I learned that the NVMe's go into the cache pool and unassigned drives. Now my array slots 1 to 3 are empty and start at slot 4. It's not a big deal, but I'd like to keep things tidy and in order, because I've found over the years that if somethings a little out of order, it leads to more things being out of order and more problems that get harder and harder to fix.

Question:

1: Can I simply stop the array and set slot 4 to none, and then set sot 1 to the drive that was in slot 4?.

2: Can I do this with subsequent drives?

3: Does unraid identify the drive by its serial number, or slot allocation? i.e will a docker look for data on drive serial number xyz5527ac or just slot 4?
4: Will this effect any shares?

5: Will this effect parity at all? Will I lose any data? (Vast family photo/video collection extremely important)

 

Thanks in advance,

 

Peter

 

If you haven't parity disk, you can freely change its allocation order, just don't wrongly assign data disk in parity, this will overwrite it and lost data.

 

Unraid recognize disk by disk serial no., pls take some photo for org. config before make any change.

You cannot do what you want as simply as you would like  

 

do you have Single or Dual parity?    With single parity there is a way to achieve what you want while maintaining parity protection as the slot number is not part of the calculations for parity1.  With dual parity it is not as easy as for parity2 the disk slot number is part of the parity calculation.

 

regardless - I assume you have backups of this important data as parity is no substitute for a backup.
