hi Pat,
I think the other thing we should probably look for would
be to see the tcp dump of what uid/gid parameters are sent over
network when this command is executed.

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?
-------------------------------------------------------------------------------------------------
This issue was not being seen before the migration. We have
copied the /etc/passwd and /etc/group files from the
front-end machine (the client) to the data server, so they
all match
-------------------------------------------------------------------------------------------------
Could you give stat output of the directory in question
from both the brick and the nfs client

Hi,
Another piece of data. There are 2 distinct volumes on
the file server
1. a straight nfs partition
2. a gluster volume (served over nfs)
The straight nfs partition does respect the group write
permissions, while the gluster volume does not. Any
suggestions on how to debug this or what additional
information would be helpful would be greatly appreciated
Thanks

Hi
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.
Thanks
