RN104 New Volume
Could not see this particular problem, forgive me if I have missed it and started another thread for nothing.
I have a new RN104, I started it for the first time with a new 4TB disk and followed the instructions on the little set up guide. including registering online. Having realised it was not simple to add more disks I decided to buy another disk and add it before I put anything on the memory. I loaded the second disk 4TB again, new and identical to the first, did the factory reset, and waited 'several' hours until the volume was rebuilt. The machine shows I have 2 disks (2x4TB) but only lists available space as 3.63TB, same as before I added the 2nd disk. I have done the factory reset again and waited the 12 hours or so but it still says the same. I have included a screenshot
I know a bit about computers but nothing about NAS and I am using this forum as my guide.

- With RAID-1 the two disks are mirrored, so adding the second drive does not add capacity - it adds redundancy. If you hot-insert a third 4 TB drive the space will increase to 7.2 TiB, and the NAS will switch to RAID-5. You still have redundancy which protects against a single drive failure.
If you wanted jbod (no RAID) then you should start over with another factory reset (with only one drive installed), switch to FLEXRAID/JBOD, and hot-insert the second drive.
Adding a new disk to the RN104 is easy, I am puzzled by your comment on "not simple to add more disks".

- thanks mdgm. give me few minutes, I need to move it from where it is, I can't access both front and back simultaneously
- ??? I thought that it would be like the RAM check when a pc boot up.... 9 minutes and continuing.... 11.. 13... how long does it normally take? More important, will any message STAY until I go out of the menu, or I have to stay and catch it before it disappears? 16:30..
- I think the test runs for about 4 hours. This is an extended memory test.
- thanks mdgm. it has just done 1h now, I did put a camcorder on it . . I'll report tomorrow, it's 2:30am in the UK
- mdgm, Stephen: returning to the original post

I will also put a link there to this post, for further reference - Hi all. I had 3x3TB caviar red hdd into my rn104. Last week I hot install the 4th, wait it to rebuild but at the end not increase the capacity, it remain to 5.5 tbyte. I read about to reboot the system and I did also but remain to 5.5 instead of 9. Have you suggestions? Thanks a lot.
Try downloading the logs, and look in mdstat.log and volume.log for the status of the newly added disk.
