cyruspy Posted December 1, 2020 Share Posted December 1, 2020 (edited) Hi!, I just built a new unRAID machine with v6.8.3, and after adding two cache devices I don't see a BTRFS mirror: Quote root@nas01:~# btrfs fi usage /mnt/cache/ Overall: Device size: 186.80GiB Device allocated: 25.03GiB Device unallocated: 161.77GiB Device missing: 500.00MiB Used: 21.23GiB Free (estimated): 162.54GiB (min: 81.66GiB) Data ratio: 1.00 Metadata ratio: 1.50 Global reserve: 16.00MiB (used: 0.00B) Data,single: Size:22.00GiB, Used:21.22GiB (96.48%) /dev/sdf1 22.00GiB Metadata,single: Size:1.00GiB, Used:0.00B (0.00%) /dev/sdf1 1.00GiB Metadata,DUP: Size:1.00GiB, Used:400.00KiB (0.04%) /dev/sdf1 2.00GiB System,single: Size:32.00MiB, Used:16.00KiB (0.05%) /dev/sdf1 32.00MiB Unallocated: /dev/sdf1 161.28GiB missing 500.00MiB Is there something I'm missing? nas01-diagnostics-20201201-2051.zip Edited December 1, 2020 by cyruspy Quote Link to comment

cyruspy Posted December 2, 2020 Author Share Posted December 2, 2020 Hello, Tried to do that, the start turned button turned grey when I unassigned the non-used (missing?) disk. Then I distroyed everything and started from scratch and now seems to be working properly.

You just needed to check a box next to the start button to allow starting anyway, but yes, now looks fine. Quote Link to comment
