[SOLVED] Adding NVME Drives to Cache

Featured Replies

I had (5) 2.5" SSDs running in my machine as Cache and needed some more space so I added (2) 2TB M.2 NVME drives that I had been using as Unassigned Drives, but not longer needed for that purpose.  The new NVME drives now show up as Cache drives, but I didnt gain any size from them (Currently still stuck at 7TB).  I have done a full BTRFS balance twice and no luck, Any ideas?

Are you asking I attach my Diagnostics on here? Do you need the whole zip file or just parts of it?

Plug your drive sizes and RAID level into this page and see what you get.

9TB, I was at 7TB before I added the (2) 2TB NVME drives, but thats where I'm still at after adding.

Log is being spammed with PCIe errors so not easy to analyze, but the NVMe devices are not part of the pool, try this:

 

-reboot (mostly to clear the log)

-stop array (if set to auto-start)

-unassign both NVMe devices

-start array, stop array

-re-assign both NVMe devices to the pool

-start array, if total/free space still doesn't change please post new diags.
