- instance failovers when the instance is stopped do not check for free
RAM, so that failing over a stopped instance is possible in low memory
situations
- rapi uses queries for tags instead of jobs (for less job traffic), and
for cluster tags it won't talk to masterd at all but read them from
ssconf
- a couple of error handling fixes in RAPI
- drbd handling: improved the error handling of inconsistent disks after
resync to reduce the frequency of "there are some degraded disks for
this instance" messages
- fixed a bug in live migration when DRBD doesn't want to reconnect (the
error handling path called a wrong function name)
- fix a couple of bugs (validation, argument checks)
- fix ``gnt-cluster getmaster`` on non-master nodes (regression)
- some small improvements to RAPI and IAllocator
- make watcher automatically start the master daemon if down
- change the OS list to not require locks; this helps with big clusters
- fix ``gnt-cluster verify`` and ``gnt-cluster verify-disks`` when the
volume group is broken
- ``gnt-instance info``, without any arguments, doesn't run for all
instances anymore; either pass ``--all`` or pass the desired
instances; this helps against mistakes on big clusters where listing
the information for all instances takes a long time
- miscellaneous doc and man pages fixes
- Change the internal locking model of some ``gnt-node`` commands, in
order to reduce contention (and blocking of master daemon) when
batching many creation/reinstall jobs
- Fixes to Xen soft reboot
- No longer build documentation at build time, instead distribute it in
the archive, in order to reduce the need for the whole docbook/rst
toolchains
- Now the cfgupgrade scripts works and can upgrade 1.2.7 clusters to 2.0
- Fix watcher startup sequence, improves the behaviour of busy clusters
- Some other fixes in ``gnt-cluster verify``, ``gnt-instance
replace-disks``, ``gnt-instance add``, ``gnt-cluster queue``, KVM VNC
bind address and other places
- Some documentation fixes and updates
- More documentation updates, now all docs should be more-or-less
up-to-date
- A couple of small fixes (mixed hypervisor clusters, offline nodes,
etc.)
- Added a customizable HV_KERNEL_ARGS hypervisor parameter (for Xen PVM
and KVM)
- Fix an issue related to $libdir/run/ganeti and cluster creation
- Xen PVM and KVM have switched the default value for the instance root
disk to the first partition on the first drive, instead of the whole
drive; this means that the OS installation scripts must be changed
accordingly
- Man pages have been updated
- RAPI has been switched by default to HTTPS, and the exported functions
should all work correctly
- RAPI v1 has been removed
- Many improvements to the KVM hypervisor
- Block device errors are now better reported
- Many other bugfixes and small improvements
- Version 2 is a general rewrite of the code and therefore the
differences are too many to list, see the design document for 2.0 in
the ``doc/`` subdirectory for more details
- In this beta version there is not yet a migration path from 1.2 (there
will be one in the final 2.0 release)
- A few significant changes are:
- all commands are executed by a daemon (``ganeti-masterd``) and the
various ``gnt-*`` commands are just front-ends to it
- all the commands are entered into, and executed from a job queue,
see the ``gnt-job(8)`` manpage
- the RAPI daemon supports read-write operations, secured by basic
HTTP authentication on top of HTTPS
- DRBD version 0.7 support has been removed, DRBD 8 is the only
supported version (when migrating from Ganeti 1.2 to 2.0, you need
to migrate to DRBD 8 first while still running Ganeti 1.2)
- DRBD devices are using statically allocated minor numbers, which
will be assigned to existing instances during the migration process
- there is support for both Xen PVM and Xen HVM instances running on
the same cluster
- KVM virtualization is supported too
- file-based storage has been implemented, which means that it is
possible to run the cluster without LVM and DRBD storage, for
example using a shared filesystem exported from shared storage (and
still have live migration)
- Change the default reboot type in ``gnt-instance reboot`` to "hard"
- Reuse the old instance mac address by default on instance import, if
the instance name is the same.
- Handle situations in which the node info rpc returns incomplete
results (issue 46)
- Add checks for tcp/udp ports collisions in ``gnt-cluster verify``
- Improved version of batcher:
- state file support
- instance mac address support
- support for HVM clusters/instances
- Add an option to show the number of cpu sockets and nodes in
``gnt-node list``
- Support OSes that handle more than one version of the OS api (but do
not change the current API in any other way)
- Fix ``gnt-node migrate``
- ``gnt-debug`` man page
- Fixes various more typos and small issues
- Increase disk resync maximum speed to 60MB/s (from 30MB/s)
- new ``--hvm-nic-type`` and ``--hvm-disk-type`` flags to control the
type of disk exported to fully virtualized instances.
- provide access to the serial console of HVM instances
- instance auto_balance flag, set by default. If turned off it will
avoid warnings on cluster verify if there is not enough memory to fail
over an instance. in the future it will prevent automatically failing
it over when we will support that.
- batcher tool for instance creation, see ``tools/README.batcher``
- ``gnt-instance reinstall --select-os`` to interactively select a new
operating system when reinstalling an instance.
- when changing the memory amount on instance modify a check has been
added that the instance will be able to start. also warnings are
emitted if the instance will not be able to fail over, if auto_balance
is true.
- documentation fixes
- sync fields between ``gnt-instance list/modify/add/import``
- fix a race condition in drbd when the sync speed was set after giving
the device a remote peer.
- note: the allowed size and number of tags per object were reduced
- fix a bug in ``gnt-cluster verify`` with inconsistent volume groups
- fixed twisted 8.x compatibility
- fixed ``gnt-instance replace-disks`` with iallocator
- add TCP keepalives on twisted connections to detect restarted nodes
- disk increase support, see ``gnt-instance grow-disk``
- implement bulk node/instance query for RAPI
- add tags in node/instance listing (optional)
- experimental migration (and live migration) support, read the man page
for ``gnt-instance migrate``
- the ``ganeti-watcher`` logs are now timestamped, and the watcher also
has some small improvements in handling its state file

- Experimental readonly, REST-based remote API implementation;
automatically started on master node, TCP port 5080, if enabled by
``--enable-rapi`` parameter to configure script.
- Instance allocator support. Add and import instance accept a
``--iallocator`` parameter, and call that instance allocator to decide
which node to use for the instance. The iallocator document describes
what's expected from an allocator script.
- ``gnt-cluster verify`` N+1 memory redundancy checks: Unless passed the
``--no-nplus1-mem`` option ``gnt-cluster verify`` now checks that if a
node is lost there is still enough memory to fail over the instances
that reside on it.
- ``gnt-cluster verify`` hooks: it is now possible to add post-hooks to
``gnt-cluster verify``, to check for site-specific compliance. All the
hooks will run, and their output, if any, will be displayed. Any
failing hook will make the verification return an error value.
- ``gnt-cluster verify`` now checks that its peers are reachable on the
primary and secondary interfaces
- ``gnt-node add`` now supports the ``--readd`` option, to readd a node
that is still declared as part of the cluster and has failed.
- ``gnt-* list`` commands now accept a new ``-o +field`` way of
specifying output fields, that just adds the chosen fields to the
default ones.
- ``gnt-backup`` now has a new ``remove`` command to delete an existing
export from the filesystem.
- New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path
have been added. Using them you can enable/disable acpi and pae
support, and specify a path for a cd image to be exported to the
instance. These parameters as the name suggest only work on HVM
clusters.
- When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and
PAE support will be set to the previously hardcoded values, but the
(previously hardcoded) path to the CDROM ISO image will be unset and
if required, needs to be set manually with ``gnt-instance modify``
after the upgrade.
- The address to which an instance's VNC console is bound is now
selectable per-instance, rather than being cluster wide. Of course
this only applies to instances controlled via VNC, so currently just
applies to HVM clusters.
- more tweaks to the disk activation code (especially helpful for DRBD)
- change the default ``gnt-instance list`` output format, now there is
one combined status field (see the manpage for the exact values this
field will have)
- some more fixes for the mac export to hooks change
- make Ganeti not break with DRBD 8.2.x (which changed the version
format in ``/proc/drbd``) (issue 24)
- add an upgrade tool from "remote_raid1" disk template to "drbd" disk
template, allowing migration from DRBD0.7+MD to DRBD8
- fix ``gnt-instance modify`` breakage introduced in 1.2.1 with the HVM
support (issue 23)
- add command aliases infrastructure and a few aliases
- allow listing of VCPUs in the ``gnt-instance list`` and improve the
man pages and the ``--help`` option of ``gnt-node
list``/``gnt-instance list``
- fix ``gnt-backup list`` with down nodes (issue 21)
- change the tools location (move from $pkgdatadir to $pkglibdir/tools)
- fix the dist archive and add a check for including svn/git files in
the future
- some developer-related changes: improve the burnin and the QA suite,
add an upload script for testing during development
- experimental HVM support, read the install document, section
"Initializing the cluster"
- allow for the PVM hypervisor per-instance kernel and initrd paths
- add a new command ``gnt-cluster verify-disks`` which uses a new
algorithm to improve the reconnection of the DRBD pairs if the device
on the secondary node has gone away
- make logical volume code auto-activate LVs at disk activation time
- slightly improve the speed of activating disks
- allow specification of the MAC address at instance creation time, and
changing it later via ``gnt-instance modify``
- fix handling of external commands that generate lots of output on
stderr
- update documentation with regard to minimum version of DRBD8 supported
- Log the ``xm create`` output to the node daemon log on failure (to
help diagnosing the error)
- In debug mode, log all external commands output if failed to the logs
- Change parsing of lvm commands to ignore stderr
- Another round of updates to the DRBD 8 code to deal with more failures
in the replace secondary node operation
- Some more logging of failures in disk operations (lvm, drbd)
- A few documentation updates
- QA updates
- Change configuration file format from Python's Pickle to JSON.
Upgrading is possible using the cfgupgrade utility.
- Add support for DRBD 8.0 (new disk template ``drbd``) which allows for
faster replace disks and is more stable (DRBD 8 has many improvements
compared to DRBD 0.7)
- Added command line tags support (see man pages for ``gnt-instance``,
``gnt-node``, ``gnt-cluster``)
- Added instance rename support
- Added multi-instance startup/shutdown
- Added cluster rename support
- Added ``gnt-node evacuate`` to simplify some node operations
- Added instance reboot operation that can speedup reboot as compared to
stop and start
- Soften the requirement that hostnames are in FQDN format
- The ``ganeti-watcher`` now activates drbd pairs after secondary node
reboots
- Removed dependency on debian's patched fping that uses the
non-standard ``-S`` option
- Now the OS definitions are searched for in multiple, configurable
paths (easier for distros to package)
- Some changes to the hooks infrastructure (especially the new
post-configuration update hook)
- Other small bugfixes
