[Linux-cluster] Cluster 3.0.3: compile error

[David Merhar]

RHEL 5.4
kernel 2.6.31.1
corosync 1.1.0
openais 1.1.0

corosync and openais install without issue.

...
/root/cluster-3.0.3/gfs/gfs_mkfs/device_geometry.c: In function  
'device_geometry':
/root/cluster-3.0.3/gfs/gfs_mkfs/device_geometry.c:33: error:  
'O_CLOEXEC' undeclared (first use in this function)
/root/cluster-3.0.3/gfs/gfs_mkfs/device_geometry.c:33: error: (Each  
undeclared identifier is reported only once
/root/cluster-3.0.3/gfs/gfs_mkfs/device_geometry.c:33: error: for each  
function it appears in.)


My testing environment is vm.

Any place to start looking?

Thanks
