automount in status D

[Carsten Aulbert <carsten.aulbert@aei.mpg.de>]

Hi all,

we have a weird problem here and I fear I need to reboot the box
(painful, many users involved), but maybe there is a way out:

I'm automounting many nodes and usually everything seems to work nicely.
However, I'm seeing this here right now:

# ps aux|grep auto.node
root      2022  0.0  0.0  30304  1240 ?        Ds   Jun19   0:21 /usr/sbin/automount --pid-file=/var/run/autofs/_atlas_node.pid --timeout=5 /atlas/node yp auto.node_local
root     11489  0.0  0.0  30516  1108 ?        D    Jun26   0:00 /usr/sbin/automount --pid-file=/var/run/autofs/_atlas_node.pid --timeout=5 /atlas/node yp auto.node_local
root     28610  0.0  0.0   2736   656 pts/31   S+   10:03   0:00 grep auto.node


As you can see there are two automounter processes in D (or Ds) state sitting there for the same mount point (the PID-file contains 2022). 

My questions:

Any idea how this happened?

Any idea how to get this resolved (possibly without a reboot)?

TIA

Carsten
