Unable to Grow RAID - New drive added as Spare

  • Trying to grow my RAID by adding a hard drive.


    I tried adding a drive and it is now listed as a spare and I can't grow the RAID.


    I used the Grow button in OMV .


    How do I tell it it is not a spare but it is part of the RAID?

  • I setup OMV 2.1 in a VM and the process worked fine.


    I had a 4 disk RAID and I hit the grow button, I saw the progress go by and then when it was done I saw it added the drive properly not as a spare and I was able to go to the file sysetm and resize that properly.


    Did something change in OMV 3.X or is it broke?

  • I went ahead and did a clonezilla image of my current setup.


    I then formatted and reinstalled OMV 2.1 and now the drive is in the process of resizing properly. I have about 24 hours until it is finished.


    Not sure what changed in 3.X but the removal of this feature that worked in 2.1 seems strange to me.
