Red Hat Bugzilla – Bug 59909
NFSv3 not *really* supported
Last modified: 2008-05-01 11:38:01 EDT
Using two RH 7.2 boxes with the 2.4 kernel, attempts to mount NFS over TCP fail,
but the same attempt over UDP works:
station14# mount -o tcp server1:/export/kickstart /mnt/kickstart
nfs server reported server unavailable: Address already in use
station14# mount server1:/export/kickstart /mnt/kickstart
Not only is the NFSv3 implementation broken, but the error messages are
extremely bizarre. What about "Address already in use" indicates "server does
not support TCP"?
NFS/TCP is reported to function in later kernels, and will probably
function in an upcoming release.
You can, if you like, test our skipjack beta to confirm.
It doesn't work with 2.4.18-0.4 on both server and client.
And it still fails with the completely bogus error message.
2.4.18-0.13 also doesn't work.
though I would be eternally grateful if y'all would patch in neil's server-side
