Readynas 204 Hot Swap Question
Hi, I have a dilemma which I am sure there is a simple explination but, here goes anyway. I have a Readynas 204 with 4 x 4tb drives in raid 0 and I want to start upgrading them to 6tb or 8tb driv...
Thanks for the reply.
I am making my methodology overcomplicated but basically, what I am trying to do is transfer the data on a full drive onto a new higher capacity drive using the nas itself but, I have 4 drives populating the nas already.
What I want to know is, what will happen if I pull a working drive/ volume out of the nas to make space for the new drive, transfer the data and pull the old drive out. Then re-instal the drive I had to pull in the begining.
Will the drive function as before? Will I lose the data?

How many volumes do you have now? If you only have one RAID-0 volume on the volumes tab, then you will lose all your data when you remove one of the drives.
My mistake, I thought I had Raid 0 but I actually have 4 volumes in JBOD. Sorry I thought Raid 0 meant no raid.
You might be able to
- power down
- remove a drive from slot A
- power up, and install a new drive in that slot
- create a new volume
- create temporary share names for each share
- use backup jobs to transfer data from slot B
- destroy the old volume
- rename the temporary shares
- power down, and insert the original disk in slot A
- power up.
I haven't tried it though, and if it doesn't work you will lose some data.
One potential problem - one of your volumes has /.apps and /home on it. If you destroy that volume, the system will first move that stuff to a new drive. But if you simply remove it, I don't know how it will behave.
Luckily, the apps/ home folder is on a different drive so, all good there. I can live with having to re-load the data but it would save a serious amount of time if it just works again.
I will give it a go and post the results in case of future enquires.
Thanks again for the help.
