I am looking for any guidance in this. I currently have a UnionFS mount setup with 2 x 4TB drives. This is also setup in Snapraid with a 3rd 4TB drive as the parity drive. I have recently gotten hold of 2 more 4tb drives and I would like to add to my current UnionFS mount/file system to extend it without losing any data.
Now in OMV I am able to edit the current Union mount in the "Union Filesystems" section under storage. I add the 2 new drives so that it shows all 4. When I go back to the "file systems" section under storage, the entry still shows the old amount of space and has not updated to the sapce for all 4 drives.
My question is, how do I extend that current file system entry without losing any data?
