hi,
would you please paste your "/install/postscripts/remoteshell" on you MN?
The following lines in the end of the remoteshell script should be there
to work around this:
````
...
# check whether the sshd daemon has been started successfully
# As we known that for rh7 the sshd cannot be started by systemctl in
chroot mode
ps aux | grep -v grep | grep sshd
if [ $? -ne 0 ]; then
if [ -e "/usr/sbin/sshd" ]; then
/usr/sbin/sshd
fi
fi
...
````
thanks

This can be seen in the debug messages:

May 3 10:01:59 node802 xcat: + eval systemctl restart sshd
May 3 10:01:59 node802 xcat: ++ systemctl restart sshd
May 3 10:01:59 node802 xcat: Running in chroot, ignoring request.
