      Add a migration type global hypervisor parameter · e71b9ef4
      Iustin Pop authored
      
      
      Since migration live/non-live is more stable (e.g.) for Xen-PVM versus
      Xen-HVM, we introduce a new parameter for what mode we should use by
      default (if not overridden by the user, in the opcode).
      
      The meaning of the opcode 'live' field changes from boolean to either
      None (use the hypervisor default), or one of the allowed migration
      string constants. The live parameter of the TLMigrateInstance is still a
      boolean, computed from the opcode field (which is no longer passed to
      the TL).

      Add an early release lock/storage for disk replace · 7ea7bcf6
      Iustin Pop authored
      
      
      This patch adds an early_release parameter in the OpReplaceDisks and
      OpEvacuateNode opcodes, allowing earlier release of storage and more
      importantly of internal Ganeti locks.
      
      The behaviour of the early release is that any locks and storage on all
      secondary nodes are released early. This is valid for change secondary
      (where we remove the storage on the old secondary, and release the locks
      on the old and new secondary) and replace on secondary (where we remove
      the old storage and release the lock on the secondary node.
      
      Using this, on a three node setup:
      
      - instance1 on nodes A:B
      - instance2 on nodes C:B
      
      It is possible to run in parallel a replace-disks -s (on secondary) for
      instances 1 and 2.
      
      Replace on primary will remove the storage, but not the locks, as we use
      the primary node later in the LU to check consistency.
      
      It is debatable whether to also remove the locks on the primary node,
      and thus making replace-disks keep zero locks during the sync. While
      this would allow greatly enhanced parallelism, let's first see how
      removal of secondary locks works.

      Some improvements to gnt-node repair-storage · 7e9c6a78
      Iustin Pop authored
      
      
      Currently the repair storage has two issues:
      
      - down instances are aborting the operation, even though they should be
        ignored (it's not technically possible to know their disk status
        unless we would activate their disks)
      - if the VG is so broken that disks cannot be activated via gnt-instance
        activate-disks or gnt-instance startup, it's not possible to repair
        the VG at all
      
      The patch makes the opcode skip down instances and also introduces an
      ``--ignore-consistency`` flag for forcing the execution of the LU.

      Unify the query fields for the storage framework · 620a85fd
      Iustin Pop authored
      
      
      This patch unifies the query fields in the storage framework for all
      types. Note that the information is still computed on-demand, so if e.g.
      the used disk space is not requested for the ‘file’ type, it won't be
      computed on nodes.
      
      Summary of changes:
      - improve the LVM storage type to support multiple lvm fields in the
        LIST_FIELDS declaration and constant (not-computed via lvm commands)
        fields
      - rename utils.GetFilesystemFreeSpace to utils.GetFilesystemStats
        returning tuple of (total, free)
      - add used and free as valid fields for lvm-vg (use being computed as
        vg_size-vg_free)
      - make allocatable accepted for all types (ones which are always
        allocatable always return True)
      - add a new list field ‘type’ that gives the current selected type; not
        much useful today (except for understanding what the default output
        is) but in the future might help if we want to list multiple types
      - add type, size and allocatable to the default output field list
      - update the man page with details on how, for file storage, size ≠ used
        + free for non-mountpoint cases

      Documentation updates · c71a1a3d
      Iustin Pop authored
      
      
      Our admin guide was very very trivial. This patch updates it to contain
      advice on when to use which commands, removes the instance
      administration part from the installation guide (moved to the admin
      guide), and adds a walkthrough document that should be useable as a
      starting point for new admins.
      
      The patch also adds emacs variables to the documents, and rewraps some
      which were not already at 72 chars.
      
      The doc updates also show backwards-compatible commands for Ganeti 2.0,
      as we don't have a good up-to-date 2.0 document and people might refer
      to this set of documentation even when running that.

      Add a node powercycle command · f5118ade
      Iustin Pop authored
      
      
      This (somewhat big) patch adds support for remotely rebooting the nodes
      via whatever support the hypervisor has for such a concept.
      
      For KVM/fake (and containers in the future) this just uses sysrq plus a
      ‘reboot’ call if the sysrq method failed. For Xen, it first tries the
      above, and then Xen-hypervisor reboot (we first try sysrq since that
      just requires opening a file handle, whereas xen reboot means launching
      an external utility).
      
      The user interface is:
      
          # gnt-node powercycle node5
          Are you sure you want to hard powercycle node node5?
          y/[n]/?: y
          Reboot scheduled in 5 seconds
      
      The node reboots hopefully after sending the reply. In case the clock is
      broken, “time.sleep(5)” might take ages (but then I suspect SSL
      negotiation wouldn't work).

      Add a ‘tags’ field to instance and node listing · 130a6a6f
      Iustin Pop authored
      Currently there isn't any easy way to list all nodes or instance and
      their tags; you have to query each node in turn, or list all the tags
      via something like “gnt-cluster search-tags '.*'”. Of course, this is
      not optimal.
      
      The patch adds a new fields to “gnt-instance list” and “gnt-node list”
      called ‘tags’, that will list the tags of the object in comma-separated
      form. This field will be empty if there are no tags (when using a
      separator this output can still be parsed by other scripts).
      
      At opcode level, there is a new fields called ‘tags’ that returns a
      (python) list of the object tags.

      Improve the documentation of query output fields · d8a4b51d
      Iustin Pop authored
      The gnt-node and gnt-instance list commands have a customizable list of
      output fields, but the list is not up to date (in the man page) and not
      easily understandable from the ‘--help’ output.
      
      This patch updates the man pages and adds the available fields and
      default fields in the ‘--help’ output, as part of the description.
      
      Example:
      Usage
      =====
        gnt-node list
      
      Lists the nodes in the cluster. The available fields are (see the man page for
      details): name, pinst_cnt, pinst_list, sinst_cnt, sinst_list, pip, sip,
      dtotal, dfree, mtotal, mnode, mfree, bootid. The default field list is (in
      order): name, dtotal, dfree, mtotal, mnode, mfree, pinst_cnt, sinst_cnt.

      Implement gnt-node evacuate · a5bc662a

      This patch adds a new 'evacuate' subcommand to gnt-node. The command
      will do a replace disks for all instances having that node as secondary
      with the new target being the new node given.
      
      The syntax is:
        gnt-node evacuate src_node target_node
      
      The command by itself doesn't do any resource checks, and instead relies
      on the LUFailoverInstance code to do that.
