I was curious if anyone here had any ideas or experience with this problem. I created the tracker for this yesterday when I woke up to find all 3 of my SSD OSDs not running and unable to start due to this segfault. These OSDs are in my small home cluster and hold the cephfs_cache and cephfs_metadata pools.
To recap, I upgraded from 10.2.10 to 12.2.2, successfully swapped out my 9 OSDs to Bluestore, reconfigured my crush rules to utilize OSD classes, failed to remove the CephFS cache tier due to http://tracker.ceph.com/issues/22754, created these 3 SSD OSDs and updated the cephfs_cache and cephfs_metadata pools to use the replicated_ssd crush rule... fast forward 2 days of this working great to me waking up with all 3 of them crashed and unable to start. There is an OSD log with debug bluestore = 5 attached to the tracker at the top of the email.
My CephFS is completely down while these 2 pools are inaccessible. The OSDs themselves are in-tact if I need to move the data out manually to the HDDs or something. Any help is appreciated.
