Hello ceph-users,
we are using a low number of rbd.ko clients with our luminous cluster.
Where can i get information about the following questions:
* Which features and cluster compatibility is provided by the rbd.ko module
of my system?
(/sys/module/rbd/**, "modinfo rbd" not seems to provide to provide useful
information on Ubuntu 16.04/18.04)
* Ubuntu 16.04/18.04 (kernel 4.15) /sys/bus/rbd/supported_features lists
feature compatibility 0x187
Is there a convenient way to find out whats provided with that kernel?
* Is there a overview for kernel releases for features and cluster
compatibility?
-> i.e. which kernel version is needed to use the fast-diff feature
* What is the development-roadmap for features and cluster compatibility in
rbd.ko?
* Available documentation http://docs.ceph.com/docs/luminous/rbd/rbd-ko/ and
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/Documentation/ABI/testing/sysfs-bus-rbd?h=v4.20.5
do not provide any significant information regarding the described
questions.
Did i missed important information resources?
Best regards
Marc
