I did my best to contain relevance above. > > First question, the statement ""...Resilient Storage is not base...". There has been a shift from 7 to 8 that I don't understand. RHEL 7 provides dlm in ResilientStorage, then CentOS 7 provides dlm in base [1]. The dlm package is still part of ResilientStorage in RHEL 8, but can't be provided? I wasn't able to find any answer to why that was changed. Can you provide any insight to the shift? > > Second question, the current advice seems to be "dlm will be in centos-stream and you should use that." However, tdawson made a pretty explicit statement: "If people are running their production machines on CentOS Stream ... well, in my opinion, that's their problem."[2] These statements appear contradictory. > > Just trying to piece this all together so I can explain to my peers the business and community decisions going on here. > > Currently someone that set up a cluster with gfs2 in 7 can't do the same thing in 8 due to the dlm package missing. That is a loss of functionality and seems to indicate it's a bug or intentional reduction in feature set. Yes, it is different than CentOS Linux 7. I'm sorry, that is just the way it is.

Should we plan for that to be removed as a great deal of the rpms are in common between HA and RS? Thank you, Judd
