Update documentation for the text backend
Update hbal man page to note that we use stddev
We actually use stddev and not the coefficient of variance (as wronglynoted before), so we update the documentation appropriately.
We also note that the dynamic load values must be pre-normalized, sincewe don't do such a normalization in the code.
Update documentation for the iextags
Use either \- or \(hy in manpages
This reduces warnings from lintian when building Debian packages.
Allow overriding the field list in -p
The print nodes option can now accept an optional field list tocustomise the output. This is ugly, since the field names do not matchthe header names, but it is at least barely customisable (at runtime).
Update hspace manpage with tiered allocation info
Also fixes some other small issues in man pages.
Change the default dynamic usage to baseUtil
This fixed the unbalanced secondary instances on partially emptyclusters, and helps in general for the cases where real utilisation datais not available.
Fix hbal man page w.r.t. --print-instances
The ordering was wrong, was showing node list details under--print-instances.
Update hbal manpage with details about dynutil
Show the load on nodes in node lists
The strange printf usage is due to some limitation (it seems) in ghc forvery long argument lists. The whole printout should be rewritten later.
Allow displaying the instance map in hbal
This is similar to --print-nodes, but with much fewer fields.
Update the hbal manpage w.r.t. job execution

Implement support for 'cheap' moves only
This patch adds support for cheap (failover/migrate) operations only inthe balancing algorithm and in the hbal command line options.
This allows a very quick balancing (compared to allowing replace-disks)which can be useful as a scheduled operation.
Man page updates
This patch beautifies the man pages for hbal and hspace.
Update documentation for the new luxi backend
Remove hn1 and related code
hn1 was deprecated for a while and this patch removes it altogether. Thesupport code in Cluster.hs is also removed.
Some documentation updates for the new parameters
Add a man page for hspace
Add copyright/license information
This doc-patch adds copyright and license information to (hopefully) allneeded files.
Allow overriding the RAPI port/scheme
This patch adds a very dumb way to override the port and scheme forRAPI: if the master string doesn't contain a colon, we consider it asimple hostname specification, and thus prepend ‘https://’ and append‘:5080’, (the default RAPI port); otherwise, we consider it a fully...
Add support for 'offline' nodes
This patch drops compatiblity with Ganeti 1.2 and adds support foroffline nodes in the cluster. When reading from RAPI, the drained nodesare considered offline so that we don't allocate on them too.
hbal: add a --quiet option
This option is the opposite of the --verbose option, and it allowsdecreasing the verbosity level from the default of one to zero (whichcurrently doesn't show the warning messages for missing disk/memory).
hbal: Add a new min-score option
This new parameter causes the algorithm to finish (or even not start atall) if we reach/have a score better than it.
Update man pages with the env variables
This patch documents the environment variables in the man pages of hbaland hn1.
More man page updates
This moves some data from README to the man pages and has other generalimprovements.
Documentation updates
This patch adds a man page for hscan and updates the README and otherman pages with the latest changes.
Add node memory field to Node objects
This patch adds a new n_mem field to the node objects, and implementsread/save/show support for it. The field is not currently used (exceptin the node list) but will be used for checking data consistency andinstance up/down status.
Show offline nodes in the node status list
This patch adds a new ‘-’ flag for the node status which denotes offlinenodes.
Add a man page for hn1 and update the hbal one
A new man page and typos fixed in hbal.1.
Add a manpage for hbal
