Hello,

I am running a Grizzly multi-host test cluster on RHEL6. On the controller node, there are several keystone-signing-XXXX files automatically created by the daemons. But if some disk cleanup scripts kick in and remove them, that will cause problem to the services. So I wonder if I can move them to a more permanent place like /var/cache/ ? Any advice and best practice experience on this will be greatly appreciated.
Yes, so long as the services get config option knowing where to look for the files, they can and should live in /var/cache. That is what RDO does by default. /tmp is a "safe default and developer friendly" solution, but not necessary for a live deployment.


$ ls -lrt /tmp

 keystone-signing-tdtD3g
 keystone-signing-swift
 keystone-signing-nova
 keystone-signing-eEXjn_
 keystone-signing-xwSFNi
 keystone-signing-YqxWd2

Thanks,
Xin
