Hi, we've just updated from pacific(16.2.15) to quincy(17.2.7) and everything seems to work, however after some time radosgw stops responding and we have to restart it. At first look, it seems that radosgw stops responding sometimes during recovery. Does this maybe have to do something with mclock https://docs.ceph.com/en/quincy/rados/configuration/mclock-config-ref/ ? ceph.conf looks something like this: -------- [global] fsid = ... mon initial members = x1,x2 mon host = # public network = 192.168.0.0/24 auth cluster required = none auth service required = none auth client required = none ms_mon_client_mode = crc osd journal size = 1024 osd pool default size = 3 osd pool default min size = 2 osd pool default pg num = 128 osd pool default pgp num = 128 osd crush chooseleaf type = 1 [osd] osd_scrub_begin_hour = 18 osd_scrub_end_hour = 6 osd_class_update_on_start = false osd_scrub_during_recovery = false #scrub during recovery osd_scrub_max_interval = 1209600 osd_deep_scrub_interval = 1209600 osd_max_scrubs = 3 osd_scrub_load_threshold = 1 [client.radosgw.mon2] host = mon2 # keyring = /etc/ceph/ceph.client.radosgw.keyring log_file = /var/log/ceph/client.radosgw.mon2.log rgw_dns_name = ... rgw_frontends = "beast port=4444" rgw_max_put_param_size = 15728640 rgw_crypt_require_ssl = false rgw_max_concurrent_requests = 2048 -------- We have nginx in front of rgw which upstream is set to client.radosgw.mon2 port 4444. Kind regards, Rok
