      Implement disabling of file-based storage · cb7c0198
      Iustin Pop authored
      
      
      Rationale: the file-based storage backend can add/remove files under a
      certain directory. However, the master node is also controlling the
      setting of the file-based root directory, so basically it means we can't
      prevent arbitrary modifications by the master of the node's filesystem.
      
      In order to mitigate this for setups where the file-based storage is not
      used, we introduce a new setting at ./configure time, that controls the
      enable/disable of file-based storage. Since this is not modifiable by
      the master (over RPC), it is now possible in this case to prevent
      unintended modifications of the node's filesystem from the master.
      
      The new setting is used in bdev.py to not expose the file-based storage
      at all, and in cmdlib.py to prevent attempts at creation of such
      instances.

      Add capability to use syslog for logging · 551b6283
      Iustin Pop authored
      
      
      This patch adds a configure-time parameter that will set the defaults
      used by all programs, and command-line parameters in the daemons that
      allow overriding it.
      
      Syslog 'yes' enables syslog in addition to file-based logging, 'only'
      enables syslog and disables file-based syslog.
      
      The log entries will be of the form:
      Jan 27 08:45:04 node2 ganeti-noded[14504]: INFO 172.24.227.5:50850 PUT
      /jobqueue_update HTTP/1.0 200
      Jan 27 08:45:05 node2 ganeti-noded[14505]: INFO 172.24.227.5:50853 PUT
      /lv_list HTTP/1.0 200
      
      and (for a multi-threaded program):
      Jan 27 08:51:48 node1 ganeti-masterd[15491]: (MainThread) INFO
      ganeti-masterd daemon startup
      Jan 27 08:51:49 node1 ganeti-masterd[15491]: (MainThread) INFO
      Inspecting job queue

      Add a crude disable for DRBD barriers · 89b70f39
      Iustin Pop authored
      
      
      Ideally we want to/will have per-device DRBD controls of disk/metadata
      flushes. In the meantime, we want at least a disable of the barrier
      functionality for cases where one has battery-backed caches.
      
      Background: DRBD has four mechanism of handling ordered disk-writes.
      From the drbdsetup man-page, these are: barrier, flush, drain and none.
      DRBD prior to 8.2 only has drain and none. This patch makes all 8.x
      versions of DRBD disable all methods, and revert to none, in case one
      fully trusts batteries (either UPS for the whole system or battery for
      NVRAM).

      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
