Hi guys, I deploy an efk cluster and use ceph as block storage in kubernetes, but RBD write iops sometimes becomes zero and last for a few minutes. I want to check logs about RBD so I add some config to ceph.conf and restart ceph.
Here is my ceph.conf:
[global]
fsid = 53f4e1d5-32ce-4e9c-bf36-f6b54b009962
mon_initial_members = db-16-4-hzxs, db-16-5-hzxs, db-16-6-hzxs
mon_host = 10.25.16.4,10.25.16.5,10.25.16.6
auth_cluster_required = cephx
auth_service_required = cephx
auth_client_required = cephx
osd pool default size = 3
[client]
debug rbd = 20
debug rbd mirror = 20
debug rbd replay = 20
log file = /var/log/ceph/client_rbd.log
I can not get any logs in /var/log/ceph/client_rbd.log. I also try to execute 'ceph daemon osd.* config set debug_rbd 20’ and there is also no related logs in ceph-osd.log.
How can I get useful logs about this question or How can I analyze this problem? Look forward to your reply.
Thanks
