puppet apply. error: cannot generate tempfile `/tmp/puppet...'
问题
在Centos服务器上，我在使用puppet apply时遇到错误：
puppet apply \
--verbose \
--modulepath=modules \
--node_terminus=exec \
--external_nodes=$PWD/modules/puppet/files/hostinfo/nodeclassifier.rb \
--color=true \
--no-daemonize \
--no-usecacheonfailure \
--server=notahost \
--config=$PWD/modules/puppet/files/puppet.conf \
--debug \
manifests/site.pp
debug: 正在执行 '/opt/puppet-data/puppet/modules/puppet/files/hostinfo/nodeclassifier.rb [主机名]'
无法执行: 无法生成临时文件 `/tmp/puppet20230712-12431-18iovt1-9`
另外，文件系统是可读写的：
[root@host puppet]# echo "Test" > /tmp/puppet20230712-4607-ywx98g-9
[root@host puppet]#
以及文件夹属性：
# lsattr /
...
----------I---- /tmp
...

你的 /tmp 目录有32000个子目录。这是ext3文件系统的限制，也可能适用于其他文件系统。如果Puppet试图创建的文件实际上是一个目录，那么失败的尝试并不奇怪。其他软件也会受到影响。
清理你的 /tmp 文件夹应该可以解决这个问题。
你还应该尝试确定为什么你的 /tmp 首先会填满，然后采取适当的措施防止再次发生。你可以考虑使用Puppet的Tidy资源类型，或者systemd-tmpfiles服务，或者修改生成/tmp子目录并未清理它们的任何软件。
英文:
Your /tmp directory has 32000 subdirectories. This is the limit for ext3, and maybe for other filesystems, too. If the file Puppet is trying to create is in fact a directory, then it is not surprising that the attempt fails. Other software will be affected, too.
Cleaning out your /tmp folder should resolve the issue.
You should also try to determine why your /tmp filled so full in the first place, and take appropriate measures to prevent that from happening again. You could consider Puppet's Tidy resource type for that, or the systemd-tmpfiles service, or perhaps modifications to whatever software is generating subdirectories in /tmp and failing to clean them up.
