I'm running two machines, one ("leng") running a Red Hat 2.4.9-31
kernel, the other ("ulthar") running a 2.4.18+lowlatency kernel. On
"leng", I have ISO images of the Red Hat 7.3 install CDs mounted through
loopback, and exported via NFS. "ulthar" mounts the images via NFS from
"leng":

This is working fine for accessing the data on the Red Hat images from
"ulthar", unless I am trying to access a large file. If I do on
"ulthar":
[root@ulthar root]# ls -l /tmp/XFree86-4.2.0-8.src.rpm
ls: /tmp/XFree86-4.2.0-8.src.rpm: No such file or directory
[root@ulthar root]# cp /mnt/rh73/SRPMS1/SRPMS/XFree86-4.2.0-8.src.rpm
/tmp
cp: reading `/mnt/rh73/SRPMS1/SRPMS/XFree86-4.2.0-8.src.rpm': No such
file or directory
[root@ulthar root]# ls -l /tmp/XFree86-4.2.0-8.src.rpm
-rw-r--r-- 1 root root 9977856 Jul 1 22:30
/tmp/XFree86-4.2.0-8.src.rpm
[root@ulthar root]#
As you can see, it does a partial copy and then fails with a "No such
file or directory" error. The size of the file after the failed copy
varies - sometimes I've seen up to 26MB be copied (the actual size of
the file is 42M). No errors are listed in the system logs of either
system. Copies from the loopback filesystem to a local file on "leng"
succeed, as are copies from an ext3 filesystem on "leng" to "ulthar"
over NFS - the problem only seems to happen with the combination.
Does anyone have any idea about what's going on? Thanks!
