I've added a new disk to unraid and everything went smooth but when i transfer a new file, it's says that i don't have enought space. All the other disk are full so it's normal that unraid cannot write to these disk but i don't understand why it doesn't write to the new one.

 

see the screenshot attached.

Are you writing to a user share?

 

Is the user share set to include only certain disks?

 

Does the user share have split level settings that require the file you are writing to be grouped with files already on the other disks?

 

Does Global Share Settings include only certain disks?

This is almost certainly a settings issue, as trurl noted.  I suspect you have a user share that's set to include only disks 2 and 3; or possibly your global settings are limited to the same.    Simply update those settings and all will be well 

In the folder share settings, i have:

 

Included disk = all

Split level = manual, do not automaticly split directories

Allocation method = High water

 

In the global share settings, i have:

 

enable disk share = yes

enable user share = yes

include disks = all

 

 

In the folder share settings, i have:

 

Included disk = all

Split level = manual, do not automaticly split directories

Allocation method = High water

 

In the global share settings, i have:

 

enable disk share = yes

enable user share = yes

include disks = all

with the Split Level as manual you have to manually create the top level folders on the new disk before it will start being used.

i changed the config to have the Automatic split any directory as required and it solved the problem.

 

thank you very much everyone!
