We have just migrated our data to a new file server (more space, old server was showing its age). We have a volume for collaborative use, based on group membership. In our new server, the group write permissions are not being respected (e.g. the owner of a directory can still write to that directory but any other member of the associated group cannot, even though the directory clearly has group write permissions set). This is occurring regardless of how many groups the user is a member of (i.e. users that are members of fewer then 16 groups are still affected).
the relevant fstab line from the server looks like localhost:/data-volume /gdata glusterfs defaults 0 0
and for a client:
mseas-data2:/gdata /gdata nfs defaults 0 0
Any help would be greatly appreciated.
