I'm new to OMV and just starting playing with it under Virtualbox running OMV 3.0.94.
I created a RAID5 Array with 4 disks and used EXT4 for the file system. Created 1 share.
I attempted to add 2 additional drives to the existing array from the GUI in an attempt to Grow/extend (add to the existing size of the array) however you want to refer to is as, but the GUI simply adds them as Spares.
I've searched, before posting, and all I've found are references to people giving up, backing up their data, and recreating a new array including the new drives.
This is a simple task under most operating systems, OK I'll say it, a Windows server. I can't believe this is a difficult task under OMV?
**Update** - I found a work around from the CLI, however I'd still like to know if there's a way to do this from the GUI?
