Is it possible to change a WD EX4100 storage from JBOD Configuration to Spanning without loosing the data???
I have only 1 drive installed configured as JBOD. I need to install the second drive. As I need both drivers to be presented as one, it’s necessary to convert the configuration to Spanning.
How can I do it without loosing the data?

So yes, all your data WILL be gone. You need to have that data elsewhere, and copy it back in when the process is complete.
