If you note the odr-cluster subscription its is attempting to use a starting version 4.13.0-114, but the catsrc on the managed clusters (potentially) are at 4.13.0-121, so this base version would never be found, hence the failure.

This happens, as the hub attempts to install the same version on the managed clusters, which results in the dr-cluster requiring the 114 version of the subscription. This would happen on an initial install, further upgrades (say ODF on the managed clusters from 114 -> 121) would update the dr operator bundles appropriately.

This is not a bug per-se, and if a user requires that the hub be older than the managed cluster, then the ramen hub configmap needs to be edited to provide appropriate starting CSV versions for the installs on the managed cluster.

This potentially needs some documentation, if at all any, to handle such install situations. Moving this to the doc component at present for a decision regarding the same.
