showmount -e to a SLES 11 server only shows the first range on each share

I am having an odd issue with the NFS exports being reported from a SLES 11.1 NFS server.

Here's what's happening. I have an /etc/exports like:

Code:

/foo   10.32.214.64/26(rw,insecure,sync,no_subtree_check) 10.32.212.0/23(rw,insecure,sync,no_subtree_check) 10.32.211.128/25(rw,insecure,sync,no_subtree_check)

And /usr/sbin/exportfs -vra shows:

Code:

$ sudo /usr/sbin/exportfs -vra 
exporting 10.32.214.64/26:/foo
exporting 10.32.212.0/23:/foo
exporting 10.32.211.128/25:/foo

And clients from all three ranges can access the shares. But when I try to list the mounts using "showmount -e" - from the SLES 11.1 server or an Ubuntu 10.04 client - only the first range is shown:

Code:

$ sudo /usr/sbin/showmount  -e 
Export list for bar-server:
/foo       10.32.214.64/26

This caused a big "WTF? that can't be right" while debugging an NFS issue.

Anyone seen this before? The showmount man pages are identical on the server and client. showmount -e to non-SLES 11 NFS servers show all exported ranges, as expected:

Code:

$ showmount -e bar-old
Export list for bar-old:
/foo       10.32.214.64/26,10.32.212.0/23,10.32.211.128/25

The showmount is the same version on all machines (-v)? What about copying the working version to the other machines, maybe just to your ~/bin or so? The last output you gave is the one I also would expect.

I don't see any indication of it, but maybe it's checking an environment variable? (Yes, I'm grasping at straws.)
