Seen it a lot where a product update has release notes but some key piece of information is missing. This has impacted me a little bit but has the potential to severely impact others. Red Hat Virtualisation 4.2 has been released and a new feature implemented there does this:
1. when the VDSMD service starts up, it checks for an /etc/multipath.conf
2. if the multipath.conf is different to the default one provided by VDSMD, then it's removed and replaced with the default one

👍👍👍👍

I was not even aware that my config was wiped out. I'll be doing some work this weekend to resolve.

Agh! I hate when that happens!

Seems like that is a just a "cp -f multipath.conf /etc/multipath.conf" with extra steps. I really hate installers that do this. If I made a conscious effort to modify a file then maybe those modifications are important.

Yes I agree. On one hand I'm annoyed but on the other hand it looks like my feedback to Red Hat through our issues, has made its way back to the opensource upstream (or downstream, I get these wrong) and has then fed it's way back again through the Red Hat product back to me. Taken around two years or so.

Just asked RedHat to show me where this information is located, either in the release notes or elsewhere. And if it's not there, then to find out why.  :mrgreen:

They responded and said:
QuoteThe information which we have discussed in this case is not available in RHV documentation as that is a configuration related to storage and not RHV. But, we have knowledge base solution specially prepared for RHV regarding multipath ( as we shared it earlier) which explains default parameters of multipath.conf required for RHV

🙈

My reply was very long. I also asked how I was supposed to prepare for this upgrade and avoid the issue. Also asked how many of their other customers have this pending issue, unaware. Also asked what repercussions would there be if a large financial company suffered severe monetary loss due to outage; directly related to the missing information from the release note and an upgrade.

Basically, it's not a problem until it is a problem, and then it's a BIG problem...
