Error ensuring InstallPlan: etcdserver: request is too large

[masonhuemmer]

Attempted to use OLM to install v0.14.1.
I am on a cloud provider and have no access to etcd.

Downgraded to 0.14.0 resolved my issue.

Response from cloud provider.

For stability and performance reasons, I don’t think they will change anything, even because changing —max-request-bytes in etcd is a last resort, and not really suggested… By default the maximum should be 1 MB per key/value pair, if you have a CRD that is larger, maybe there is something wrong with the design, and it’s better to split it in some way.

I also faced this issue on v0.14.1, and everything is working on v0.14.0.

We might need to reduce the CSV/InstallPlan size. I will take a look.
