ReadyNas 104 replace disk 1
Hi, I have a ReadyNAS 104 with 3 of the bays in use and I would like to add the fourth disk (I'm using RAID1).
Ideally, I would like to add the new disk in bay 1 (as I assume this is the system disk where the OS is installed?) and then move the disk in bay1 to bay4. The capacity of the new disk is 5 TB (as is the existing disk in bay 1).
How can I do this without loosing my data? Is my assumption about the OS drive correct --- or should I just add the new disk in bay 4?

You are running FlexRAID/JBOD (one volume per disk). So all you need to do is hot-insert the additional drive in bay 4, and create a new volume (data_4) on the disk.
The NAS always uses mdadm (software RAID), even with JBOD. So it does report RAID-1 in this situation, even though there actually is no RAID redundancy.

RAID1 - assuming not degraded - with three storage blocks? No....

No, this isn't ...

Time to review your intention.
I suspect you are using XRAID
Can you post a screenshot of the volume page in the admin web ui?
The OS is redundantly installed on every drive, so you needn't worry about that. You do not want to be moving the drives around -- it serves no useful purpose and has the potential for making things confusing.
If you started with two drives in XRAID RAID1 and added the third, then you have RAID5, not RAID1. If the 5TB is the largest drive, then you currently have unused space on it that will be used once you install another 5TB for redundancy. If you really do have RAID1, then likely that 5TB isn't being used at all. All this will be answered by the screen shot StephenB asked for. Chances are, you simply need to insert the new drive in the empty slot, but wait till we have a look at the screen shot to be sure.
Hi,
Thanks for your replies
I'm not at home ATM, so can't provide a screenshot, but I'm not using xraid, so I guess it makes sense for me to just add the disk in the 4th bay - I was just puzzled that the admin UI tells me I'm running RAID1 .. 🙂
I'll see if I can add a screenshot later today or tomorrow morning, just to make sure..
Kind regards
