I am worried that linkSrc can be confused with what "src" is. What about:

 def _linkStorageDomain(self, linkTarget, linkName):
     ...
     currentLinkTarget = os.readlink(linkName)
     ...
     else:
          if linkTarget == currentLinkTarget:
     ...

linkTarget/Name are the official arguments of "ln", it is nice to maintain the 
names.

Line 1124:             if e.errno != errno.ENOENT:
Line 1125:                 self.log.error("Can't link SD %s to %s", src, 
linkName,
Line 1126:                                exc_info=True)
