Hi guys,
I have an OpenMediaVault NAS configured with 4 WD Red 4TB in a RAID5 array.
I want to add 2 new disks to this array and unfortunately I cannot find how to do it.
I physically installed the disks in the server and start the NAS.
I click on Grow button in the RAID management tab but my disks were shown in spare in the details (below the details with one added disk, I decided to unplug the other one to perform the extension with one disk at a time...).
I have read several posts and it seems that a command line can solve this issue (mdadm --grow...) but I don't know where to enter this command.
If I connect a screen and a keyboard to my server I have a login line but if I enter my login and pswd the page actualize and ask me again login and pswd.
I am a complete beginner in NAS and Linux in general so I hope that someone can help me
Thank you in advance!
