Lordbye Posted March 28, 2023 Share Posted March 28, 2023 (edited) hi, i had a single ssd cache drive (240gb), now i added a second ssd (120gb) but unraid cache is still only 240gb (not 240+120) and afer reboot is full used (188gb) and move doesn't start how can i use all cache space? and how can force to start mover? when i click "move" that what happens: "emhttpd: shcmd (525): /usr/local/sbin/mover &> /dev/null &" and stop Edited March 28, 2023 by Lordbye Quote Link to comment
apandey Posted March 28, 2023 Share Posted March 28, 2023 Multi device pools can only be btrfs raid, and you cannot mix drives of different sizes Quote Link to comment
Lordbye Posted March 28, 2023 Author Share Posted March 28, 2023 so i can't use second cache disk Quote Link to comment

Lordbye Posted March 28, 2023 Author Share Posted March 28, 2023 ah ok, i have only one pool. so is better a new larger disk Quote Link to comment
Solution JorgeB Posted March 28, 2023 Solution Share Posted March 28, 2023 By default adding a second device will create a raid1 pool, so only 120GB would be usable in this case, if you want to use the full capacity of both devices convert to single profile: https://forums.unraid.net/topic/46802-faq-for-unraid-v6/?do=findComment&comment=480421 Quote Link to comment
apandey Posted March 28, 2023 Share Posted March 28, 2023 Ah, interesting. I didn't know there is a JBOD mode Quote Link to comment
itimpi Posted March 28, 2023 Share Posted March 28, 2023 2 hours ago, Lordbye said: so i can't use second cache disk You can, but if you use the (default) RAID1 profile then with 2 drives of different sizes the usable space is that of the smaller drive. If you want the full space to be available then you can switch the pool to the Single profile at the expense of losing redundancy. Quote Link to comment
