Bug#404447: nfs-kernel-server: Transferred files get currupted
Hello,
yesterday I reinstalled Etch on my NSLU2 and hit this bug with NFS.
I should note, though, that while this problem shows every time I
transfer a big file (700MB) from my laptop to the NSLU2 over 802.11g
WLAN, I can't always reproduce it when I transfer the same file from my
desktop system over 100Mbps Ethernet.
On the desktop system the problem shows only 2 out of 10 times.
In both systems I used rsync for transferring the files back and forth
and during the transfer from NSLU2 to the desktop I was getting a solid
5-5.5 MBps speed the whole time. Sending the file from the desktop to
the NSLU2 the speed varied from 20MBps -- in the beginning -- to 700KBps
with ocassional freezes.
Both the desktop and the laptop systems run Sid and mount the NFS share
with these options: "nfsvers=3,tcp,hard,intr".
On the NSLU2 I've installed linux-image-2.6.18-3-ixp4xx and have these
options in /etc/exports: "no_root_squash,subtree_check".
I tried setting sysctl net.ipv4.tvp_wmem to "4096 8192 8192" and "4096
16384 16384" but it didn't fix the problem.
On my previous setup with slugOS and the proprietary ethernet driver I
didn't have such problems but the maximum speed I got was about 3MBps.
