Brief description of the problem

This happens when I try to create a share on a newly created pool.
The pool is created using RAID 6 using 5 x 10GB SAS drives that are connected to a HBA.

@Dilson Hello there.
Re:

The parity raids of btrfs-raid5 and btrfs-raid6 are read only by default in our upstream OS base of openSUSE - that is why you are seeing the read-only message. They are not considered production ready and we indicate this in our Web-UI. However if you are game to risk things a little take a look at our approach to resolve this - if you really want to use the far less mature parity btrfs-raid levels:

https://rockstor.com/docs/howtos/stable_kernel_backport.html

Either that or you got the Tumbleweed route. As it has a far newer kernel and upstream, as a result, does not enforce a read-only state.

Hope that helps.
