Yes, found chapter 22, but I was thinking of some mentioning in "man 4 md" or "man -k md"... Also the admin guide is a "american manual" (tell you what to do, but not how it works). In the meantime I also found a LWN article that explains some details, but I would expect such documentation to be part of the OS...or at least some file in the rpm package: # rpm -ql cluster-md-kmp-default-4.12.14-197.18.1.x86_64 /lib/modules/4.12.14-197.18-default /lib/modules/4.12.14-197.18-default/kernel /lib/modules/4.12.14-197.18-default/kernel/drivers /lib/modules/4.12.14-197.18-default/kernel/drivers/md /lib/modules/4.12.14-197.18-default/kernel/drivers/md/md-cluster.ko The description just says: Description : Clustering support for MD devices. This enables locking and synchronization across multiple systems on the cluster, so all nodes in the cluster can access the MD devices simultaneously.
