@ramhound got it. now should i repost this as an answer or can you undelete it? i am pretty sure my answer does not 100% anwer the question but at least it answers a portion of it so it's not useless.

thank you for this answer. as i am new to this platform, i cannot upvote answers but i still did. finding a solution is a mess and tends to generate data that is useless or even misleading, so removing that part does make sense in a way even if you cannot know how the solution was actually found. it may even be subject do NDA, which i absolutely did not think about at all.

@ramhound yes, i edited the answer because the initial claim was that it was unrelated to the question, which was true. you asked me to edit it. i didnt know that i should have given another answer and flagged the old one as "unfixable by editing."(or sth like that, its described in the flags)

@ramhound if there is such a disclaimer and i missed that, then please go on and delete it. i do not want to cause trouble. but if you say it was only on WBM, then we have to take it as a given that he changed his mind.

@ramhound my last comment was on superuser.com/questions/1594658/… you mean the other part about the 11hrs and the reboot. i got that when you mentioned it the first time, i got it when scott repeated it... is there a reason you are putting it a third time on the plate?

@ramhound oh i have edited that post about the software raid failed and missing. but the system said that it cannot be undeleted. too bad it contains step-by-step information with the correct information on the specific issue.
