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

Multi device pools can only be btrfs raid, and you cannot mix drives of different sizes

so i can't use second cache disk

Not as a part of same pool. You can always use it as a separate single disk pool if you want different cache pools for different shares

ah ok, i have only one pool. so is better a new larger disk

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:

Ah, interesting. I didn't know there is a JBOD mode

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.
