I am not sure -- it should with NFSv3 though. Does "mount -v" tell you anything more detailed? I suppose that nfsstat may also be used -- the "commit" count should only increase when it does an NFSv3 commit operation. > The NFS server is mounted with: > > mount_nfs -c -P -a 0 -r 8192 -w 8192 -i -o rw,noatime,nointr host:/path > /nfs/host/path So the only really visible difference is 6 nfsiod versus 20 nfsiod. I think if you increased the nfsiod on that 4.x box to something much higher it would deadlock the same, then, assuming that all else is equal. -- Brian Fundakowski Feldman \'[ FreeBSD ]''''''''''\ <> [EMAIL PROTECTED] \ The Power to Serve! \ Opinions expressed are my own. \,,,,,,,,,,,,,,,,,,,,,,\ _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
