Currently there is an inconsistency for failing the member drives for arrays with different RAID levels. For RAID456 - there is a possibility to fail all of the devices. However - for other RAID levels - kernel blocks removing the member drive, if the operation results in array's FAIL state (EBUSY is returned). For example - removing last drive from RAID1 is not possible. This kind of blocker was never implemented for raid456 and we cannot see the reason why. We had tested following patch and did not observe any regression, so do you have any comments/reasons for current approach, or we can send the proper patch for this?

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
