Windows: When adding many host entries, some fail with "Permission denied" errors #9528
Open
Description
Describe the Bug
When adding many host entries on Windows, using host resources, some sometimes fail with
Puppet::Util::FileType::FileTypeFlat could not write C:/Windows/System32/drivers/etc/hosts: Permission denied @ rb_sysopen - C:/Windows/System32/drivers/etc/hosts
while the other ones are added just fine.
Expected Behavior
All host entries should be added w/o error
Steps to Reproduce
Use the following class to add many host entries to a new Windows node (possibly in a setup with at least 20-30 other nodes):
class hosts {
# Let each host create a host entry as exported resource
$nic = $facts['networking']['primary']
$ip = $facts['networking']['interfaces'][$nic]['ip']
@@host { $facts['networking']['fqdn']:
comment => 'Host entry generated by Puppet',
host_aliases => [$facts['networking']['hostname']],
ip => $ip,
tag => ['HOST_RECORD'],
}
# Collect all exported host records and add them to (C:/Windows/System32/drivers)/etc/hosts
Host <<| tag == 'HOST_RECORD' |>> { ensure => present }
}Environment
- Version: 7
- Platform: Windows Server 20xx
