Me neither ;-) .
Background:
I introduced some new functions. One is:
${rootfs}_chroot_needed: default 0 => yes. Means we need a chroot. I.e. for 
nfsv3 and localfs this returns 1 cause they don't need a chroot. So we are 
not going to build it.

Do you have a rootfs type in /etc/cluster/cluster.conf of fuse.glusterfs? 
Cause clusterfs-lib.sh just tries to call ${rootfs}_chroot_need if it exists.

What did I say!

Another new thing. It should be pretty easier or even much better to track 
this one cause the shutting down and rebooting should have been improved much 
more. Another new function helping with this is:

${rootfs}_get_userspace_procs: If this function is implemented it returns a 
list (separated with \n) of processes that need to stay running until the 
very end. With rhel5 gfs it is:

function gfs_get_userspace_procs {
  local clutype=$1
  local rootfs=$2

  echo -e "aisexec \n\
ccsd \n\
fenced \n\
gfs_controld \n\
dlm_controld \n\
groupd \n\
qdiskd \n\
clvmd"
}

This list goes to /etc/xkillall_procs. /etc/xkillall_procs is read when 
calling halt and is a list of processes that will not get killed from 
killall5/killall9. For this we added a new option to killall5/9 the [-x 
{processname}]*. I'm going to file some bugs for fedora and rhel5 today and 
make more documentation for this on open-sharedroot.org so that the (I call 
it xfiles) are to be taken into account from the initscripts.

Additionally to xkillall_procs there will be a /etc/xrootfs and /etc/xtab:
/etc/xrootfs: is the rootfs type that will not be umounted from either netfs 
or network.
/etc/xtab: are mountpoints that should not get umounted from 
netfs/network/halt. These are i.e. /cdsl.local and if need 
be /var/comoonics/chroot..

Take the new rpms I've uploaded right away.

And thanks for your input.

Marc.
