Issue following command: nvme set-feature -f 0xf -v 0 /dev/nvme1n1 # disable keep-alive timer nvme admin-passthru -o 0x18 /dev/nvme1n1 # send keep-alive command will make keep-alive timer fired and thus delete the controller like below: [247459.907635] nvmet: ctrl 1 keep-alive timer (0 seconds) expired! [247459.930294] nvmet: ctrl 1 fatal error occurred! Avoid this by not queuing delayed keep-alive if it is disabled when keep-alive command is received from the admin queue.

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.
