Hello,
See thread at the bottom. I have also problems reading files while
mounting from Ubuntu. I cannot read files larger than +/- 18KB.
/etc/exports:
/home/pieter localhost 10.0.0.1 10.0.0.2 10.0.2.15
On Ubuntu:
$ sudo mount.nfs lilium:/home/pieter pieter_mount/ -w
$ cat pieter_mount/test.txt # 17069 bytes
[ output ]
$ cat pieter_mount/test1.txt # 18483 bytes
[ no output. cat keeps running; `ps aux | grep cat`
pieter 3095 0.0 0.0 3896 244 pts/15 D+ 15:35 0:00 cat
pieter_mount/test1.txt ]
When I mount the same export on the OpenBSD machine it works fine:
$ sudo mount -t nfs localhost:/home/pieter/ /mount_test/
$ cat /mount_test/test1.txt
[output]
So could be an Ubuntu (and MacOS?) bug. I don't have another Unix/Linux
computer to try on right now.
Also, I'm not able to write on the exports. From both Ubuntu and
OpenBSD(localhost).
$ touch test
touch: cannot touch `test': Read-only file system
It says Read-only _file system_. Could this have anything to do with
file permissions or the -maproot -allmap options?
`portmap -d` and `mountd -d` gives no errors. I tried disabling pf. No
result. No interesting things in /var/log/messages
Regards,
Pieter

Hello all,
Recently, my lazy ass went from 4.6-current snap to the most recent
4.8-current snap (#647: Fri Nov 26, amd64). Machine in question is
mostly a local file server, NFS to a few Macs. I say mostly, 'cause
it
does some other stuff, and sits in a DMZ.
Since the upgrade to 4.8, I'm unable to read /some/ files from the
nfs
server to the macs. I say some, because in testing I've been able to
ascertain the following:
1. I can write any size file from the mac to the nfs server. No
issue.
2. I can write a small file (like 5 KiB), and read it back to the
Mac.
3. I can write a large file (like 700 MiB), and cannot read it back
to
the Mac.
4. I am unable to read any previously existing files on the NFS share
to
the Mac, whether they be large, or small.
Because the machine is in a DMZ, I made sure to disable the
DMZ->Internal filtering rules and stuff to rule out any stupidity.
Traffic dumps show no blocked packets.
While grasping at straws, I set vfs.nfs.iothreads=4. The
Mac is mounting the share as -o resvport,hard,intr,nolock.
The troubleshooting results thus far are just erratic enough to have
me
believe it's nothing I've done; nothing is making sense. I'm
basically
looking for corroboration here. Can anyone else replicate this?
I am experiencing something similar on 4.8-current (server) and MacOSX
10.5.8 (client). I suspect the MacOSX to be the quilty one, as no other
NFS client shows any of these symptoms.
From the mac, I can write a file to the (auto)mounted share (/media)
and read it back, but I cannot read any of the files that existed there
before I mounted. A simple 'cat /media/.../file.txt' results in nothing
(the command is still running); after a while, a window pops up saying
'Server connection interrupted: media [Disconnect]'. I can _list_ the
content of the mounted share though.
I am (auto)mounting it with -resvport,noauto,nodev,noexec,noatime.
No filtering is done in between the boxes; they are on the same LAN,
pf is not running. I need to look at what exactly the mac firewall is
doing I guess.
