[Help] Reinstalling TOS6 to remove NVMEs from TRAID
Posted: 24 Aug 2025, 13:17
Hi, all,
New Terramaster user here (coming over from QNAP) and looking for a bit of assistance.
I'm in the process of setting up a T12-500 Pro. I currently have 2x1TB NVME drives and 4x24TB HDDs installed in the unit, as well as 2x16TB RAM modules. I am installing TOS6. The volume and storage pool are currently synchronising. There is no data on the drives.
The issue I have is that I selected installation of TOS6 to NVME Disk 1 and "default" installation. As others have noticed, the unit seems to have joined all HDDs and both NVMEs - inlcuding the system NVME - into one storage pool. This is not what I want to do (nor what I expected to happen, but here we are).
What I would like / intended is:
NVME Disk 1 to have TOS and applications
NVME Disk 2 to be used for cache
HDDs to be used for data storage and the TRAID array, not the SSDs
Looking around, there seems to be a few ways of achieving this after th fact, but info is a bit conflicting. I am hoping someone can given me a proper steer as to whether the below is correct and in the correct order:
1. Delete volume and reboot
2. Delete storgae pool and reboot
3. Factory reset
4. Power down the unit (assuming it restarts after factory reset?)
5. Remove all SSDs and HDDs
6. Install only 1 SSD - the one I want the system on - nothing else (presumably, I can just reinsert without wiping as it will be wiped during installation?)
7. Once TOS is installed and up and running, install the HDDs (again, presumably, I can just insert them without wiping as they will be wiped during TRAID set up? Should I also install them in a different order - e.g. HDD1 in HDD2 bay - to avoid the unit "remembering" any previous settings / set-up?)
8. Once HDDs are installed and sychronoised, power off unit and install second SSD and designate it for caching?
Is that correct?
Thanks in advance!
