Restarting of nfs-kernel-server by udev event during booting

I am using an udev configuration which restarts the nfs-kernel-server after disks are mounted. Now I got a problem that this stops the system startup.

Synthesizing the initial hotplug events...done.
Waiting for /dev to be fully populated...[   39.464422] EXT4-fs (sdb1): Ignoring deprecated nobh option

^CSetting parameters of disc: (none).

At the line "Installing knfsd..." I must push Ctrl+C that the startup continues.

Part of udev config:

# Mount the device
ACTION=="add", ENV{dir_name}!="", RUN+="/bin/mkdir -p '/media/%E{dir_name}'", RUN+="/bin/mount -o %E{mount_options} /dev/%E{crypto}%k '/med$
ACTION=="add", ENV{dir_name}!="", RUN+="/etc/rc.local.durchsatz '%E{dev_name}'", RUN+="/etc/init.d/nfs-kernel-server restart"

I took the rootfs over from Pogoplug Pro and just added the 3.3.2 kernel. On Pogoplug Pro it was working.

shv,

I'm curious, why do you restart nfs-kernel-server when the disks are mounted? can you just re-export the nfs shares instead? (if that's what you want to do).

I want to export the drives if they are switched on after booting the device. But it can also occure that they are already up and running during the startup and this caused the problem. How can I reexport them without a restart of nfs-kernel-server?

You can do exportfs -r to reexport whatever nfs shares defined in /etc/exports
