Currently we request the latest osdmap only if ceph_pg_poolid_by_name() fails with -ENOENT. This is effective with newly created pools, but we also want to avoid attempting to map from pools that were recently deleted and report "pool does not exist" instead. (Such an attempt eventually fails in the OSD client after map check code kicks in, but the error message is confusing.) Request the latest osdmap unconditionally after bumping a ref on an existing client in rbd_client_find(). Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
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.
