Hi, I have the same problem with data corruption (with nfe on nfs
server side),
particularly when transferring large files.
Maybe this is somehow associated with the topic.
My simple test case:
truncate -s 1000m bigfile
^^ here I get zero-filed file
cp bigfile /nfs/mounted
^^ here I get not-at-all-zero-filed file, after uploading to nfs server
nfs server on 8-CURRENT as of Apr 17
nfs client on 7.0-STABLE as of Apr 12
Hi,
On a RELENG_6 client and the same RELENG_7 (now ULE) server
with nfe, all seems to work fine
