Hi,
I am building a NFS Active/Passive cluster using ext3 filesystem and I
don't know if I have a configuration issue or I come across a bug.
My service, nfs1, is started without problems but there is no nfs
export available.
I went through the list and I found this thread
http://marc.info/?l=redhat-linux-cluster&m=118764091712577&w=2
I tried to find any evidence of this by looking at bug reports and the
release notes of 4.5,4.6 and 5.0 but I couldn't find any thing.
Could you please someone give me an idea?
Regards,
Pavlos
