So, from what I can see I believe this issue is being caused by one of the remaining OSD's acting for this PG containing a snapshot file of the object /var/lib/ceph/osd/ceph-46/current/1.2ca_head/DIR_A/DIR_C/DIR_2/DIR_D/DIR_0/rbd\udata.0c4c14238e1f29.00000000000bf479__head_F930D2CA_ _1 /var/lib/ceph/osd/ceph-46/current/1.2ca_head/DIR_A/DIR_C/DIR_2/DIR_D/DIR_0/rbd\udata.0c4c14238e1f29.00000000000bf479__1c_F930D2CA__1 Both the OSD which crashed and the other acting OSD don't have this "1c" snapshot file. Is the solution to use objectstore tool to remove this "1c" snapshot object and then allow thigs to backfill? -----Original Message----- From: ceph-users <ceph-users-bounces@xxxxxxxxxxxxxx> On Behalf Of Nick Fisk Sent: 05 June 2018 16:43 To: 'ceph-users' <ceph-users@xxxxxxxxxxxxxx> Subject: FAILED assert(p != recovery_info.ss.clone_snaps.end()) Hi, After a RBD snapshot was removed, I seem to be having OSD's assert when they try and recover pg 1.2ca. The issue seems to follow the PG around as OSD's fail. I've seen this bug tracker and associated mailing list post, but would appreciate if anyone can give any pointers. https://tracker.ceph.com/issues/23030, Cluster is 12.2.5 with Filestore and 3x replica pools I noticed after the snapshot was removed that there were 2 inconsistent PG's. I can a repair on both and one of them (1.2ca) seems to have triggered this issue. Snippet of log from two different OSD's. 1st one is from the original OSD holding the PG, 2nd is from where the OSD was marked out and it was trying to be recovered to: -4> 2018-06-05 15:15:45.997225
