To help things look a little better, I would also stop the daemon for osd.6 and mark it down `ceph osd down 6`. Note that if the OSD is still running it will likely mark itself back up and in on its own. I don't think that the OSD still running and being up in the cluster is causing the issue, but it might. After that, I would increase how many PGs can recover at the same time by increasing osd_max_backfills `ceph tell osd.* injectargs '--osd_max_backfills=5'`. Note that for production you'll want to set this number to something that doesn't negatively impact your client IO, but high enough to help recover your cluster faster. You can figure out that number by increasing it 1 at a time and watching the OSD performance with `iostat -x 1` or something to see how heavily used the OSDs are during your normal usage and again during recover while testing the settings. For testing, you can set it as high as you'd like (probably no need to go above 20 as that will likely saturate your disks' performance) to get the PGs out of the wait status and into active recovery and backfilling.
