We have several OSDs that are crashing on start. We are running nautilus 14.2.16; here is the relevant bit of the log:

It seems like a version of this:
https://tracker.ceph.com/issues/45519
and maybe this https://tracker.ceph.com/issues/21087I haven't been able to get it to start with the stupid allocator. Here is the ceph.conf I've been using to try to get it to start; a thread seemed to indicate that increasing the bluefs_max_log_runway would help.
[global]
fsid =<redacted>
mon initial members = <redacted>
public_network = 10.210.20.0/22
mon_host = 10.210.20.21,10.210.20.22,10.210.20.23
auth_cluster_required = cephx
auth_service_required = cephx
auth_client_required = cephx
#kernel doesn't support all features, so disable this
#rbd default features = 3
[osd]
#set snap trim priority to lowest, 1
osd_snap_trim_priority = 1
osd_recovery_op_priority = 8
osd-max-backfills = 16
osd-max-backfills = 1
#keep allocator commented out normally; defaults to bitmap but
#may need stupid
#inspired by https://tracker.ceph.com/issues/45519
bluestore_allocator = stupid
bluefs_allocator = stupid
debug_bluefs = 20/20
#set to 3x default 4194304
bluefs_max_log_runway = 12582912
The cluster is having issues and it is urgent we get these OSDs up.
The DB is on a shared NVMe device (81G) and the disk is a 2.2TB 2.5 inch enterprise disk.
I'll be very grateful for any assistance.
Best,
Will
