[Gluster-users] group write permissions not being respected

[Pranith Kumar Karampuri]

hi Pat,
      Are you seeing this issue only after migration or even before? May be
we should look at the gid numbers on the disk and the ones that are coming
from client for the given user to see if they match or not?

Could you give stat output of the directory in question from both the brick
and the nfs client

Could you also let us know version of gluster you are using.
