Stripe size is shown as zero when no strip in back end device: [root@ceph132 ~]# cat /sys/block/sdd/bcache/stripe_size 0.0k Actually it should be 1T Bytes (1 << 31 sectors), but in sysfs interface, stripe_size was changed from sectors to bytes, and move 9 bits left, so the 32 bits variable overflows. This patch change the variable to a 64 bits type before moving bits.

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.
