Hi Mark, management is running CentOS 7.9 (upgraded from 7.4). I also upgraded 
xCAT to the latest release.

[root@headnode ~]# cat /etc/redhat-release
CentOS Linux release 7.9.2009 (Core)

[root@headnode ~]# rpm -qa xCAT
xCAT-2.16.2-snap202105201708.x86_64

Thanks.

What version of xCAT are you running?
What is the OS of the management node ?

Hello, I'm trying to update an old CentOS 7.4 cluster but genimage is failing 
during dracut phase:

# chroot /install/netboot/centos7.4/x86_64/compute/rootimg dracut  -f 
/tmp/initrd.2501.gz 3.10.0-1160.45.1.el7.x86_64
No '/dev/log' or 'logger' included for syslog logging
Turning off host-only mode: '/sys' is not mounted!
Turning off host-only mode: '/proc' is not mounted!
Turning off host-only mode: '/run' is not mounted!
Turning off host-only mode: '/dev' is not mounted!
dracut module 'xcat' cannot be found or installed.

I've looked around the web and found a lot of similar issues but no fixes at 
all. Is there anything that I can do instead of running copycds again and 
customizing everything from the ground?

Thanks all,
