[nfs-discuss] data corruption with NFS4/ZFS

[Udo Grabowski]

Now we have been able to test this with NFSv4 OSol 2009.06 snv 111b on both 
client and server, and
it gets much worse (using mirrormounts, see 
http://www.opensolaris.org/jive/thread.jspa?threadID=110515&tstart=0 
) ! 
500 out of 7000 runs show NULL entries in the files, the corruption is so 
severe that we have to go 
back to NFS v3 (although we do not know what errors and performance bottlenecks 
to expect there 
now).
