Bug 1657265

This is not a specific mdadm problem, but a packaging problem.

Hi,Nigel Croxon

The same problem occurs on the RHEL 8 beta OS. When using the RPM package to install mdadm, the same message appears.

[root@storageqe-09 ~]# rpm -ivh mdadm-4.1-rc1_3.el8.x86_64.rpm

I want to know how this problem will be dealt with next.

Hello Changhui,

Does this problem still exist with later versions of RHEL8 snapshots?

Hi，Nigel Croxon

This problem still exists in the latest RHEL-8.0-Snapshot-3.1 :(RHEL-8.0-20181220.1-x86_64-dvd1.iso)

I see this on a nightly build.

I don't know the root cause. Because I'm not familiar with the detail of rpm. Why does it complain about this. 
But it's too late to fix this problem. It's not a serious problem. It just gives a warning message. The rpm
package can be installed successfully. 

So it's better to fix this in rhel8.1

Thanks
Xiao

Hello

This seems correct to me, although I'm not a systemd expert.

This is not an RPM issue, but a systemd message: the mdadm RPM contains .service files for systemd, so when it is updated, systemd is invoked to reload its units.
/var/run is considered a legacy path, and /run is the "canonical" location, so systemd prints that message.

Also, the message quoted above is not from mdadm, but from subscription-manager (see the [/usr/lib/tmpfiles.d/subscription-manager.conf:1] prefix in the message text).
