For the records: I found that the name of the provider for gmirror mustn't exceed 15 characters. `gmirror` doesn't complain if you specify a provider name longer that 15 characters, but the mirror won't be detected. So for example it's impossible to use gptid as provider. At least this should be documented in the man page(es, I guess this restriction applies to graid3 etc. also) Perhaps it's desirable to loosen that restriction. I'm fine with 15 characters, but like mentioned gptid for example may be for some people a desirable provider name. Thanks, -Harry P.S.: My coding skills don't last for offering a diff...
