[Help] TRAID Help/Explanation

Post by doumak »

Hi!

So I'm fairly new to all of this and may need some clarification. I have a F2-223 that I've been using for about a year with a 6TB drive installed it using TRAID. Recently, I've installed a new 10TB drive thinking it would give partial redundancy space as well as expand the current storage pool. Now, after fiddling with it for a while, I realize that I either misunderstood how TRAID worked to begin with or I'm doing something wrong.

Here's a screenshot of what I'm looking at. The drives are synced, but the option to edit/expand is grayed out (which is what tipped me off that I had misunderstood what was going on). Am I right in my assumption that expansion is not possible with the current setup? If so, what are the ways I could expand storage space in my current situation? Keeping the data on the current volume is important to me, so I could see about investing in a NAS with more drive bays if it comes down to it.

Thanks for any insight!

You can replace the 6TB with another 10TB. With any raid that provides redundancy you will (effectively) "lose" 1 drive to make the redundancy. Traid is (in a 2 drive nas) equivalent to raid 1 (mirror) and there will be 4TB (approx) of "unused" space.
See this: https://support.terra-master.com/raidca ... n/?lang=en
The advantage of Traid is that you can make these increases in capacity in stages. Other typical raids would not have let you do that directly.
If you consider physical expansion you could look at DAS units (of all varieties) but some of the TM units can work with existing NAS units and utilise the TOS disk storage utilities. (You will have to research that as not my subject. The downside being even more hdd/nvme.)
F5-221 TOS7.0.0777 - 4x4TB (Ironwolf) Traid
F2-424 TOS7.0.0777 - 2x500GB nvme (P3) Traid, 2x6TB HDD (HGST) Traid
F2-221 TOS7.0.0777 - 1x3TB Ext4, 1x4TB Btrfs
F2-425+ TOS7.0.0777 - 2x500GB nvme (P3) Traid, 2x6TB HDD (EXOS) Traid
