kanif - a TakTuk wrapper for cluster management
DESCRIPTION:
kanif is a tool for cluster management and administration. It
combines main features of well known cluster management tools
such as c3, pdsh and dsh and mimics their syntax. For the effective
cluster management it relies on TakTuk, a tool for large scale remote
execution deployment.
For simple parallel tasks that have to be executed on regular machines
such as clusters, TakTuk syntax is too complicated. The goal of
kanif is to provide an easier and familiar syntax to cluster
administrators while still taking advantage of TakTuk characteristics
and features (adaptivity, scalability, portability, autopropagation and
informations redirection).
To work, kanif needs to find the "taktuk" command (version 3.2.3
and above) in the user path. The other requirements are the same as
TakTuk: it requires, on all the nodes of the cluster, a working Perl
interpreter (version 5.8 and above) and a command to log without pass-
word (such as "ssh" with proper rsa keys installed).
kanif provides three simple commands for clusters administration
and management:
kash: runs the same command on multiple nodes
kaput: broadcasts the copy of files or directories to several nodes
kaget: gathers several remote files or directories
kanif combines the advantages of several cluster management
tools. Its main features can be summarized as follows:
* C3-style configuration file for static clusters setups
* pdsh-like options such as nodes ranges and timeouts
* dshbak-like gathering, sorting and merging of output
kanif also reports a quick summary of failures: connections and
commands execution.
