(This is a copy-n-paste from a forum I put this issue on. Hopefully its legible on the ML).
I'm having an odd problem.
I have FreeNAS 8.0.2 release i386 installed on a PowerEdge SC440 with an 80GB drive setup for FreeNAS and 320GB setup for NFS.
I have the NFS share mounted on my Debian Linux (latest.."Squeeze") box as:
192.168.1.11:/mnt/StorageA/themagicm on /media/StorageA type nfs (rw,nodev,addr=192.168.1.11)
nfsstat -mount shows:
root at debianlaptop:/home/themagicm# nfsstat -mount
/media/StorageA from 192.168.1.11:/mnt/StorageA/themagicm
On the server (FreeNAS.. the share is "async" enabled).
/etc/exports looks like:
/mnt/StorageA/themagicm -alldirs -mapall=themagicm:nasgrp
I copy a 2.2GB file from the Linux box the first 500-600MB flys through
at about 30mb sec, then slows down, 29, 28, 27, 26 and so on,
decrementing down to, oh I dunno, 1mb...crawling.
So I get my wife's Macbook and do a plain jane mount..
mount 192.168.1.11:/mnt/StorageA/themagicm x
I do a "cp bigassfile.tar.gz x/."... it works NO PROBLEM.
stumped. I even tried making sure "udp" was the protocol in my mount,
but that didnt solve it. (yes I realize in my code entry above it shows
"tcp".. I tried both)
I dont have any errors in dmesg. I've tried this on openSuSE 11.4, 12.1 to see if it was a distro quirk..but it wasnt.
Thanks in advance...
