我試圖在兩個ec2實例中安裝Ceph，在此之後guide 但我無法創建osd。 我的集羣裏只有兩臺服務器，它無法創建使用此命令時分區：Ceph EC2安裝無法創建osd

在兩個磁盤，我試圖創建OSD 這發生同樣的錯誤是ceph.conf我正在使用的文件：
fsid = b3901613-0b17-47d2-baaa-26859c457737
mon_initial_members = host1,host2
mon_host = host1,host2
auth_cluster_required = cephx
auth_service_required = cephx
auth_client_required = cephx
osd mkfs options xfs = -K
public network = ip.ip.ip.0/24, ip.ip.ip.0/24
cluster network = ip.ip.0.0/24
osd pool default size = 2 # Write an object 2 times
osd pool default min size = 1 # Allow writing 1 copy in a degraded state
osd pool default pg num = 256
osd pool default pgp num = 256
osd crush chooseleaf type = 3
有沒有人知道如何解決這個問題？
