Because the feature of TRAID+ is not final ready, it has not been released to current TOS versions.
Appreciate the info! Please consider this a request for the feature, when it becomes available: That it should be possible to migrate to TRAID+ an existing TRAID array, provided it has the appropriate number of drives, and sufficient free space available to accomodate whatever additional data/parity is required to support two-drive failure redundancy protection. Thanks!
Using 2 x 16TB and 2 x 8TB HDDs to build RAID 5, the available space is 24TB instead of 32TB.slimdusty wrote: ↑03 Jan 2023, 16:20 I realise the recommendation for replacement of a failed drive is to replace it with another drive of at least the same capacity (in case of drive failure, or just replacement I presume), but would the following scenario work:
I have 2 x 16TB and 2 x 8TB drives in my F4-423 NAS set to RAID 5, which gives me ~32TB of total capacity, but I only have say 18-20TB of data stored in it so far. If I then replace one of the 16TB drive (not necessarily if it fails) with another 8TB drive, my total capacity of this RAID 5 set up will still be ~ 24TB, which is still well over the amount of data currently in my NAS.
When RAID synchronization is completed, you need to edit the volume to expand the capacity of the volume.
I guess something feels off....TMSupport wrote: ↑11 Jan 2023, 14:52When RAID synchronization is completed, you need to edit the volume to expand the capacity of the volume.

How do I calculate the capacity of a TRAID manually?
I'm asking because I started off with 5 5TB drives in TRAID which gave me a capacity of about 18TB (capacity seemed to be closer to RAID 5's N-1).
I replaced one of the 5TB with a 14TB drive, followed the instructions and repaired RAID, and I do not see any extra capacity or free space to grow the volume. Ultimately I was going to go through this process over and over till I replaced all 5 drives over the next couple of months.
