Hi,

 

I just added a new disk which is ntfs file system, and add it to a cache pool, which is 1 slot originally and I enlarge it to 2. And I also checked the format checkbox. But after I start the array, the new disk has no FS, please take a look of below screenshots.

 

Cache2 settings page

 

How can I resolve this situation? seem the new disk not join the pool?

That's normal, the fs that shows is for the entire pool, there's just one per pool.

P.S. using the default raid1 mode you'll only be able to use 1TB, it can be changed to other modes.

Thanks for the quick response, I am newbie to unraid allough I set it up 1 year ago and never change it, it just works fine.

 

Here is one more question, I think those two disk is empty(new disk should be formatted), and I did a rebalance of rail0, but the pool still report only 2T free space.

 

 

 

BTW, I installed the unassigned devices plugin, and it has some error

That's expected, it can only use 1TB from the larger disk since raid0 requires 2 devices minimum, if you want to use the full capacity you need to use single profile, all that it's in the link above.
