[linux-lvm] LVM cache/dm-cache questions.

[lejeczek]

now when you say that - (I) believe it or not - I think it's 
possible. I cannot test it, for now the LV is in production 
but! I few days ago introduced an external usb keboard which 
has not LED indicators at all and now when I play with it it 
seems there might be problem on my f24, maybe the 
drivers(?). Gee, open source with all its greatness and the 
luck of officially Christened, own hardware(laptop) can be a 
reason of great frustration sometimes.
I'll put together another cache pool some days and then 
shall provide clarification to my own frustration.
