__init__(self, lines)
(Constructor)

source code 

x.__init__(...) initializes x; see help(type(x)) for signature

Overrides: object.__init__
(inherited documentation)

GetVersion(self)

source code 

Return the DRBD version.

This will return a dict with keys:

  • k_major
  • k_minor
  • k_point
  • k_fix (only on some drbd versions)
  • api
  • proto
  • proto2 (only on drbd > 8.2.X)

GetMinors(self)

source code 

Return a list of minor for which information is available.

This list is ordered in exactly the order which was found in the underlying data.

_JoinLinesPerMinor(self, lines)

source code 

Transform the raw lines into a dictionary based on the minor.

Returns:
a dictionary of minor: joined lines from /proc/drbd for that minor

Class Variable Details [hide private]

_VERSION_RE

Value:
re.compile(r"^version: (\d+)\.(\d+)\.(\d+)(?:\.(\d+))?" r" \(api:(\d+)\
/proto:(\d+)(?:-(\d+))?\)")
