It will then prompt you to remove and replace one of the drives. Pick RAID 1 and you should see ‘Expand Capacity’ option.It’ll warn you that it’ll interrupt the current services.Under ‘Raid’ tab by ‘RAID Volume’, pick ‘Change RAID Mode’.I found expand capacity from the following:
I did not try Simone’s suggestion as my method worked just fine for me. If anyone has any details on that I’d love to hear. I think there is a way in ssh to expand the raid volume - need to dig out my old docs. I’m on the new OS 5 - so I hope they kept this feature. I hope that when this is done that I can do Change Raid Mode again - and now it will magically allow me to change capacity since both drives have only a 4 TB partition on a 5 TB disk. Again - I did the manual rebuild - which is in progress now.
I attempted again to CHANGE RAID MODE and click Raid 1 and clicked the Raid 1 checkbox - but it showed same warning - that it will erase everything. Instead I did a manual rebuild.Īfter the rebuild completed, I took out the other 4 TB drive and put in a 5 TB drive. When going to the CHANGE RAID mode button - and then selecting RAID 1 (and the Raid 1 checkbox) it WARNS me that it will erase the RAID and start anew. I took out one 4TB disk and replaced it with one 5 TB disk. Didn’t work for me - whenever I try to do RAID 1 it warns me it will erase everything on the disks.
