Hi,
I've gotten a few bug reports lately that if UDP is blocked at the server,
NFS mounts (even with -o tcp) fail. git bisect shows that the culprit is
the change "Get rid of the "-i" option for mount.nfs[4] and always use the
text-based mount(2) system call for kernel version 2.6.23 and later." -- in
other words, the bug is specific to the text interface. Does anyone know why
this would be the case?
This also fails for me. My setup is through an ssh tunnel
ssh -L2049:srv:2049 -L2050:srv:2050 -L2051:srv:2051ser@gateway
and I follow that with
strace mount localhost:/export /mountpoint \
-o nfsvers=3,port=2049,mountport=2050,...
This hangs in this kernel call
mount("localhost:/export", "/mountpoint", "nfs",
MS_NOSUID|MS_NOATIME,
"tcp,intr,fg,soft,nfsvers=3,port=2049,mountport=2050,nolock,addr=127.0.0.1"
This hack makes it work for me again:
