Hi Ahmed，
I cannot reproduce the makehosts error, could provide more information
about makehosts ?
1) Could you check if /tmp/xcat is rw? could you use non-root user?
2) when executing makehosts, is there a file "/tmp/xcat/hostsfile.lock" ?
3) Could you provide output of "lsxcatd -v", "XCATBYPASS=1 makehosts", "rpm
-qa|grep -i xcat" ?
Best Regards

Subject: [xcat-user] Error while executing makehosts command
Hi all,
I am using xCAT 2.13.4 version and the OS on my management node is Centos 6
When I try to execute "makehosts" command the foolowing error appears:
flock() on closed filehandle $lockh
at /opt/xcat/lib/perl/xCAT_plugin/hosts.pm line 451.
flock() on closed filehandle $lockh
at /opt/xcat/lib/perl/xCAT_plugin/hosts.pm line 565.
Other error appears when I try to use "switchdiscover"
switchdiscover --range 192.168.1.0/24 -w
Command failed: lsdef. Error message: Could not find an object named
'switch-192-168-1-50' of type 'node'..
Given that there isn't a problem in our switch configuration since we've
implemented an xCAT cluster before using the same switch with Centos7
management node.
Hope you can help.
Sincerely,
Ahmed Essam
