I have recently started exploring OpenCAS and so far I am very impressed with it. I am coming from configuration/testing hell with bcache and so OpenCAS is a breath of fresh air!
That said, while configuration for opencas is much better than bcache, it does have some quirks that I am unsure about.
As an example, how would I go about saving the following casadm command to my opencas.conf?
And that is pretty clearly ensuring that there is no way for me to set things like seq-cutoff (or the promotion threshold). Am I missing something or is the configuration limited on what it can apply?

Hi @miversen33 ! You are right, seq-cutoff seems to be missing in the config file.
In general that should not be a big deal, as cache saves those settings in metadata on the cache drive when they are changed. So when you seq-cutoff params with casadm command and then stop the cache, on the next start (with --load) your configuration will be restored.
As for availability of those options in opencas.conf, I think the key here is that nobody before asked for it. The project development is more or less driven by the user needs, so that may be the moment we add it to our todo list.
That makes sense. So can we consider this issue a request for that? Or maybe we close this issue in favor of #1625 and have all configurable options added to the configuration?
While configuration of Open CAS Linux via the opencas.conf file is highly recommended, the following sections detail how to manually configure Open CAS Linux options using casadm. For more details on available commands for the casadm utility, see the section Configuration Tool Details.
