Yes, definitely. The superblocks look perfectly normal for a single drive failure followed by a crash. So "--assemble --force" is the way to go. Technically you could have some data corruption if a write was under way at the time of the crash. In that case the parity block of that stripe could be wrong, so the recovered data for the missing device could be wrong. This is why you are required to use "--force" - to confirm that you are aware that there could be a problem. It would be worth running "fsck" just to be sure that nothing critical has been corrupted. Also if you have a recent backup, I wouldn't recycle it until I was fairly sure that all your data was really safe. But in my experience the chance of actual data corruption in this situation is fairly low.
