Thanks for your response, Xinyun. Yes, I disabled SELinux and the firewall for testing during setup:

[root@kickstart ~]# cat /etc/sysconfig/selinux 

# This file controls the state of SELinux on the system.

# SELINUX= can take one of these three values:

#     enforcing - SELinux security policy is enforced.

#     permissive - SELinux prints warnings instead of enforcing.

#     disabled - No SELinux policy is loaded.

SELINUX=disabled

# SELINUXTYPE= can take one of these two values:

#     targeted - Targeted processes are protected,

#     minimum - Modification of targeted policy. Only selected processes are protected. 

#     mls - Multi Level Security protection.

SELINUXTYPE=targeted

[root@kickstart ~]# systemctl status iptables.service

iptables.service - IPv4 firewall with iptables

   Loaded: loaded (/usr/lib/systemd/system/iptables.service; disabled)

   Active: inactive (dead)

Aug 27 19:21:50 kickstart.larsenhaus.org systemd[1]: Stopped IPv4 firewall with iptables.

[root@kickstart ~]# systemctl status ip6tables.service

ip6tables.service - IPv6 firewall with ip6tables

   Loaded: loaded (/usr/lib/systemd/system/ip6tables.service; disabled)

   Active: inactive (dead)

Aug 27 20:09:48 kickstart.larsenhaus.org systemd[1]: Stopped IPv6 firewall with ip6tables.

I figured out how to set the block size to 512 but it didn't help. Any other ideas would be appreciated.  :-)
