I have my EX4100 up and running with 3 x 6TB drives configured in a RAID-5 volume.
I now want to add a new 8TB drive as a JBOD volume without erasing the existing RAID-5 volume. The last step of the process is a little ambiguous for me. Following what I did (below) can I expect this to work properly and that I’ll end up with my existing volume intact with data and the new empty volume?
I’m 90% sure it’ll do what I need but that 10% it too much to risk my data.
This is what I did:
From Storage - RAID, I selected “Change RAID mode” and from there, on the “JBOD Configuration” page I select “Create new Volume(s)”
The next page presents the warnings:
- Changing the RAID mode will erase all of the data on the drives listed below.
- These drives will not be accessible while the RAID array is being created.
- Drive Self Test (DST) is performed prior to creating the volume(s).
and tests Drive-4.
Next I should select Encrypted vs unencrypted and I leave unencrypted - the volume info looks OK Volume_2 - JBOD - 7997GB
Next comes the Summary which also looks good
This section provides a summary of the configuration you just created. It will show the volume name, file format, disk size and disk array number.
Volume_2 - JBOD - EXT 4 - 7997 GB - Drive4
The final step is where I am warey as it says:
Create New Volume(s)
You are about to re-format the hard drive(s). All data will be erased. Do you want to continue?
I would feel a little warmer if it said that Volume_2 will be formatted but that message isn’t clear enough.
I am assuming that it will ONLY erase the new drive and not the existing Volume_1 (my RAID-5 set)
Can someone confirm for me?
