Description
After upgrading a 1.8 server cluster to 2.1, we are seeing this on 1.8 clients:
LustreError: 11-0: lsd-MDT0000-mdc-ffff8101b737d400: An error occurred while communicating with NID 172.16.64.141@tcp; the mds_getxattr operation failed with -95
Which is associate with us getting "No such file or directory" when we stat some files that existed before the 1.8->2.1. Not all files have this problem.
On a the lustre-discuss, there are hints that ORNL-3 may have info about this, but that ticket is closed to use so we don't really know for certain.
