Hi; Yesterday i started to upgrade my Ceph environment from 0.94.9 to 0.94.10. All monitor servers upgraded successfully but i experience problems on starting upgraded OSD daemons.
When i try to start an Ceph OSD Daemon(/usr/bin/ceph-osd) receives Segmentation Fault and it kills after 2-3 minutes. To clarify the issue i have role backed Ceph packages on that OSD Server back to 0.94.9 and problematic servers could rejoin to the 0.94.10 cluster. My environment is standard 14.04.5 Ubuntu Trusty server with 4.4.x kernel and i am using standard packages from http://eu.ceph.com/debian-hammer nothing special on my environment. I have uploaded the Ceph OSD Logs to the link below. https://drive.google.com/drive/folders/0B_hD9LJqrkd7NmtJOW5YUnh6UE0?usp=sharing And my ceph.conf is below [global] fsid = a3742d34-9b51-4a36-bf56-4defb62b2b8e mon_initial_members = mont1, mont2, mont3 mon_host = 172.16.51.101,172.16.51.102,172.16.51.103 auth_cluster_required = cephx auth_service_required = cephx auth_client_required = cephx filestore_xattr_use_omap = true public_network = 172.16.51.0/24 cluster_network = 172.16.51.0/24 debug_ms = 0/0 debug_auth = 0/0 [mon] mon_allow_pool_delete = false mon_osd_down_out_interval = 300 osd_pool_default_flag_nodelete = true [osd] filestore_max_sync_interval = 15 filestore_fiemap = true osd_max_backfills = 1 osd_backfill_scan_min = 16 osd_backfill_scan_max = 128 osd_max_scrubs = 1 osd_scrub_sleep = 1 osd_scrub_chunk_min = 2 osd_scrub_chunk_max = 16 debug_osd = 0/0 debug_filestore = 0/0 debug_rbd = 0/0 debug_rados = 0/0 debug_journal = 0/0 debug_journaler = 0/0 Thanks for all help.
