After adding physical volumes to a volume group through vgextend, the kernel will rescan the partitions. This in turn will cause the device capacity to be queried. If the device status is set to offline through sysfs at this time, READ CAPACITY command will return a result which the host byte is DID_NO_CONNECT, and the capacity of the device will be set to zero in read_capacity_error(). After setting device status back to running, the capacity of the device will remain stuck at zero. Fix this issue by rescanning device when the device state changes to SDEV_RUNNING.

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.
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.
