Line 15: Send info to represent Gluster volume as a network block device

Line 17: rpath = sdCache.produce(self.sdUUID).getRemotePath()
Line 18: rpath_list = rpath.rsplit(":")
remotePath comes from the user as part of the 'spec', typically server:/export
( in case of NFS) and server:volumename (in case of gluster). I need to extract
the volume name hence the need to split using ':'. IIUC, ':' will be present in
NFS' getRemotePath() as well. Is there a better way of doing this w/o using ':'
?
I will use maxsplit=1 for the rsplit, since it always should be of the form
server:volumename for gluster case.
Line 19: volfileServer = rpath_list[0]
Line 20: volname = rpath_list[1]
Line 21:
Line 22: # Volume transport to Libvirt transport mapping

Line 33: imgFilePath = self.getVolumePath()
Line 34: imgFilePath_list = imgFilePath.rsplit("/")
Line 35: imgFileRelPath = "/".join(imgFilePath_list[4:])
I agree, hard-coding needs to be removed. Let me see how I can do that.
4: means i need to find the path relative to the start of the mount point.
Basically the path to the image starting from the sdUUID/... bcos this gets fed
to the qemu's gluster:// cmdline that expects a path relative to the gluster
volume.
Line 36:

Line 252: self.localPathBase, "glusterSD",
I thought using os.path.join was portable and preferred ? In fact in one of my
prev. patchsets.. fsimonce had asked me to use os.path.join instead of +=.
is there any advantage of usign += here instead of the preferred os.path.join ?
I am not clear.
What i am doing here is to get a glusterSD specific mnt path something like
mnt/glusterSD/<servername:volname>.
