Hello

When I tried to stop a node, it got stuck here ( from ps afx ] :
Code: 
   6061 ?        SL     0:00  \_ startpar -p 4 -t 20 -T 3 -M stop -P 2 -R 6
   6534 ?        S      0:00      \_ /bin/sh /etc/init.d/vz stop
   6583 ?        R      0:48          \_ /sbin/modprobe -r ip_nat_ftp

there were no vz's on this node.

after 5 minutes I used kill -9 6534 un stick it.

while the node was down I made a change to /etc/pve/cluster.conf . that should not be an issue when a node is off? we have 4 nodes in this cluster.

yet here is output of fbc3 /etc/pve # ls -l /etc/pve/cluster*

bad node:
Code: 
-r--r----- 1 root www-data 1393 Aug 24 11:57 /etc/pve/cluster.conf
-r--r----- 1 root www-data 1393 Aug 27 12:33 /etc/pve/cluster.conf.new


good nodes have this:
Code: 
# node  fbc87
-rw-r----- 1 root www-data 1505 Aug 27 12:44 cluster.conf
-rw-r----- 1 root www-data 1432 Aug 23 07:56 cluster.conf.old

# node fbc241
s012  ~ # ls -l /etc/pve/clus*
-rw-r----- 1 root www-data 1505 Aug 27 12:44 /etc/pve/cluster.conf
-rw-r----- 1 root www-data 1432 Aug 23 07:56 /etc/pve/cluster.conf.old

I upgraded after reboot, restarted and have the same issue.


Any suggestions to fix?
 
I moved the network connection to a dumb switch and after two more reboots the node came back up.

Originally it was connected to a Netgear layer 3 switch.
 
Just tested a shutdown , which still hangs here:
Code: 
  14406 ?        SL     0:00  \_ startpar -p 4 -t 20 -T 3 -M stop -P 2 -R 0
  14820 ?        S      0:00      \_ /bin/sh /etc/init.d/vz stop
  14869 ?        R      0:12          \_ /sbin/modprobe -r ip_nat_ftp
 
What is the output of

# dpkg -l fuse-utils

Please remove that packages if it is still installed:

# apt-get remove fuse-utils
 
fuse-utils was installed, I removed.

The issue is still occurring. I rebooted two times and ps afx still shows:
Code: 
 7946 ?        Ss     0:00 /bin/sh /etc/init.d/rc 6
   7952 ?        SL     0:00  \_ startpar -p 4 -t 20 -T 3 -M stop -P 2 -R 6
   8339 ?        S      0:00      \_ /bin/sh /etc/init.d/vz stop
   8419 ?        R      2:50          \_ /sbin/modprobe -r ip_nat_ftp

Not this system was a pve + desktop system, now it is just a testing node.
here is most of ps afx output besides the kthreadd stuff:

This is a system that can be re-installed, or we can take the time to try to solve this. No hurry but if someone has a suggestion please respond.
