When we encounter an transport/controller errors, error recovery kicks in which performs: 1. stops io/admin queues 2. moves transport queues out of LIVE state 3. fast fail pending io 4. schedule periodic reconnects. But we also need to fast fail incoming IO taht enters after we already scheduled. Given that our queue is not LIVE anymore, simply restart the request queues to fail in .queue_rq Reported-by: Alex Turin <alex@vastdata.com> Reported-by: shahar.salzman <shahar.salzman@gmail.com> Signed-off-by: Sagi Grimberg <sagi@grimberg.me> Signed-off-by: Christoph Hellwig <hch@lst.de> Cc: stable@vger.kernel.org
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
