RN102 - additional disk not visible
Hi, I started running out of free space on ly RN102 (3TB disk, 90% used), so I bought an additional disk of 6TB. Inserted the disk; synchronisation started up. New disk is detected now, both disks ar...

Thanks for your prompt response.
Bummer, unfortunately was not aware of this calculator before buying a disk. A shame to get this kind of useless capacity
Ideally I would have- partitioned 6TB in 2 blocks of 3TB
- Consider 1 block as 'critical' data, with back-up mechanism with the existing 3TB, remaining 3TB would be non-critical data, not backed-up
Alternative would be to work without RAID, just use full 3+6TB capacity and organize some kind of scheduled back-up / protection myself. Would that be possible?

Yes. You lose the ability to upgrade capacity w/o restoring from backup (along with the loss of RAID protection). RAID protection isn't enough to keep your data safe anyway, so you do need a backup even with RAID-1. If you do this, I recommend using two volumes (one for each disk). If you use one volume (RAID-0), then you lose all data on both disks when either one fails - so it is more fragile.
The simplest way to get there is to switch to flexraid, uninstall any apps, destroy your existing volume, and create two new ones. Then put some shares on each disk and restore data from the backup. Then reinstall the apps.

OK thanks. I guess there's no way to trick the system, allowing to avoid full erase/create of the existing 3TB volume ( I will back-up anyway, but it could do some important time saving if I don't have to start from zero)?
For example: swap out old disk
Insert new 6TB disk, create volume
Insert old 3TB disk and just 'detect' it with all data still on?
Best regards
