[Gluster-users] Gluster not recognizing available space

Hi,
A tiny bit more data:
I tried restarting nfs on gluster-0-1. Following
that I was back to the original behavior of getting
"No space left on device" error messages when I tried
to write from a client. I then deleted the dummy test
directories I had made yesterday, followed by trying
to recreate them. As yesterday the first directory
is created on all bricks, although the log file on
gluster-0-1 has the same error messages as yesterday.
Again as yesterday from the client side the second
directory seems to be created successfully but no
such directory appears on gluster-0-1.
Does any of this suggest where I should look next?
Thanks.
Pat
