What were you trying to do that didn't work?

If /var/log/sa directory is missing from the system and you restart sysstat service it created /var/log/sa as a data file

Please provide the package NVR for which bug is seen:

sysstat-11.7.3-11.el8.x86_64

Steps to reproduce

1. Install sysstat-11.7.3-11.el8.x86_64
2. Remove /var/log/sa (# rm -rf /var/log/sa)
3. Restart the service  (# systemctl restart sysstat)
4. # file /var/log/sa
   /var/log/sa: data

Expected results

/var/log/sa should be a directory instead of data

Actual results

1. file /var/log/sa
   /var/log/sa: data

Workaround

Remove the /var/log/sa and reinstall the sysstat package.
