Expansion and encryption on RN104
Hello, I have the RN104 (firmware 6.2.2) My drives are: 1x1TB Western Digital Red - WD10EFRX 2x4TB Western Digital Red - WD40EFRX. First I created a X-RAID volume with encryption on 1TB disk. ...
Stareck & Stephen,
I disagree with the 5Tera & 2 Tera conclusion, from 3pm earlier, and I expect 2 Tera with that combination.

My drives are:
1x1TB Western Digital Red - WD10EFRX
2x4TB Western Digital Red - WD40EFRX.
First I created a X-RAID volume with encryption on 1TB disk. The space used for data was 1TB (no protection).
Then I added one of the 4TB disks. The space used for data was 1TB (protection).
** Say Disk1=1Tera. Disk 2 =4T.
You are using 1 Tera of the 4 Tera disk. the remaining 3T is not used. This is mirrored to the 1 Tera on the smaller disk 1.
Last I added the second 4TB disk (bay 4 is empty). The amount of space used for data grew to 2TB.
** I expect this. You are actively using 1 Tera of each of the 4 Tera disks.
Disk 1 (1Tera) + Disk2 ( 1T of 4T) ==2 Tera with Disk3( 1 T of 4T) being the parity disk.
The disks are in a single X-RAID volume (RAID 5 under 'type'). So I'm getting 2TB space used for data instead of 5TB.
It seems to be something wrong. ** I'm not surprised. Remove the 1 Tera, which is limiting matters. You have more space with 2 x 4Tera, mirroring each other. Net space is 4T minus overhead.
This is an earlier expansion discussion.
