      Implement block device renaming · f3e513ad
      Iustin Pop authored
      This patch add code for renaming a device; more precisely, for changing
      the unique_id of the device. This means:
        - logical volumes, rename the volume
        - drbd8, change the remote peer
      
      This is needed for the being able to replace disks for drbd8.

      The two function 'any' and 'all' are copied as-is from the python 2.4
      documentation for the itertools module. They are useful (and are already
      builtin function in python 2.5).

      Modify two mirror-device related rpc calls · 153d9724
      Iustin Pop authored
      The two calls mirror_addchild and mirror_removechild take only one child
      for addition/removal. While this is enough for our md usage, for local
      disk replacement in drbd8, we need to be able to specify both the data
      and metadata device. This patch modifies these two rpc calls (and their
      backend implementation and their usage in cmdlib) to take a list of
      children to add/remove.

      Initial implementation of drbd8 template type · a1f445d3
      Iustin Pop authored
      This is a partially working drbd8 template type. It does:
        - add/remove
        - startup/failover/shutdown
      
      Not working is replace disks, which needs custom code for this template.

      Currently the way we shutdown or startup disks seems to make DRBD8

      Add DRBD8 class for handling drbd version 8.x · a2cfdea2

      This duplicates some code from the DRBDev class, but not very much, and
      it will be expanded with the new functionality available for the 8.x

      Improve out-of-minors handling · 0caf6485
      Iustin Pop authored
      Currently, the out-of-minors handling is not very good: though both MD
      and DRBD functions for finding an unused minor can return None, only the
      DRBD code checks for this case.
      
      This patch improves this by making the functions _FindUnusedMinor raise
      an error instead of None, and gets rid of the one manual check for the
      return value.

      Some small improvements to the hooks environment · 0e137c28
      Iustin Pop authored
      For the configuration update hook, it's useful to have a consistent name
      for the target of the operation. As such, the LU code is modified to
      include an GANETI_OP_TARGET that points either to the cluster (name),
      node name or instance name depending on the opcode.
      
      Also, the NoHooksLU is modified such that its build env method returns
      an empty (but conformant) result. This should improve things in case by
      mistake this class' BuildHooksEnv is called.
