reverting from flexraid to two independent disks.

I have a Readynas duo V1 which has served me well over the years with 2x2TB drives in flexraid. I had a drive failure, so am now down to one drive. I tried to put in a second drive, but the second d...

HI Jenn, It might not be flexraid, probably just plan old raid-1. all I know is that it was a simple raid with redundancy, and it's still working with one disk, so I'm guessing it was just "mirroring", which is what, raid-1?

I don't want to buy another disk, but I have a 750GB disk handy that I can put into the empty slot. I'm just concerned that the NAS might think that I want to rebuild the array onto the second disk. I don't.

So will it be okay going from the remaining half of a 2TB raid-1 pair (which has good, albeit no longer redundant, data, to JBOD with the existing 2TB plus an arbitrary 750GB disk I have lying around? Are there any settings I need to change?

thanks

Hello GuyCarnegie,

If you can still access the files then that must be RAID1 and you cannot add that smaller size of disk. You need to replace the old disk that died with the same size of the existing one. Once you have a replacement 2TB, insert it to the vacant bay and the NAS should let it resync.

  Hi Jen. I realise that I can't retain the raid 1 function if I add the smaller disk. Is it not possible to revert to JBOD once I have selected to use RAID though?

    Hello GuyCarnegie,
    
    Your unit does not support JBOD.
    
    Your only option here is get a replacement disk that is with the same size of the existing and working one. As always, I strongly recommend to always have full backup.
