I set up a cluster with 12 PCs, every PC have 3 network interfaces,8GB memory, 1 Intel cort i3-4170 and 1 disk ad system root partion ,two others as ceph bluestore disk.
Here is my ceph cluster configuration:
[global]
osd crush location hook = /usr/bin/calamari-crush-location
fsid = 628e2af3-d0fd-4ad2-ae41-ac3178d37721
mon_initial_members = sd-ceph1, sd-ceph3, sd-ceph5
mon_host = 10.10.10.101,10.10.10.103,10.10.10.105
auth_cluster_required = cephx
auth_service_required = cephx
auth_client_required = cephx
osd_pool_default_size = 3
public_network = 10.10.10.0/24
cluster_network = 10.10.20.0/24
#osd_pool_default_pg_num = 2048
#osd_pool_default_pgp_num = 2048
osd deep scrub interval = 1209600
osd scrub begin hour = 20
osd scrub end hour = 9
osd max scrubs = 1
#osd scrub during recovery = false
[client]
rbd_cache = true
rbd_cache_size = 134217728
rbd_cache_max_dirty= 10444800
why did the osd crash so frequently. can i fix it whitout rebuilding the osd node.
thanks,
wang yu
