Doc Type: Release Note
Doc Text:
Previously when VDSM attempted to run getFloppyList on an NFSv4 storage domain an error was returned if the permissions of the NFS export were not set correctly, or if the VDSM host was in a different NFS domain to the storage server. This has now been fixed, and the getFloppyList command succeeds as expected.

when connecting to a storage server taht has NFSv3 with NFSv4, query of getIsoList will succeed but getFloppyList will fail with permissions error. 

Version-Release number of selected component (if applicable):

si17
vdsm-4.9.6-32.0.el6_3.x86_64

How reproducible:

100%

Steps to Reproduce:
1. have an iso domain on storage server working with NFSv3 and attach the domain to your setup
2. go to storage -> select iso domain -> images
3.

Comment 2 Eduardo Warszawski 2012-10-11 04:02:35 EDT 
If the mount is NFSv4, please check that the vdsm user is correctly configured in the mapping.
If your intention is to use NFSv3 please check your code includes patch:

storage: Default to NFSv3 if version not specified
