Question

我试图在两个ec2实例中安装Ceph，遵循此guide 但是我无法创建osd。我的群集只有两台服务器，使用此命令时无法创建分区：

ceph-deploy osd create  host:xvdb:/dev/xvdb1 host:xvdf:/dev/xvdf1

[ceph_deploy][ERROR ] GenericError: Failed to create 2 OSDs

我试图创建OSD的两个磁盘中发生了同样的错误这是我正在使用的ceph.conf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

有人知道如何解决这个问题吗？

＆gt;＆gt; ceph-deploy osd create host：xvdb：/ dev / xvdb1 host：xvdf：/ dev / xvdf1

您需要使用DATA分区开发名称和日记分区开发名称。所以就像

ceph-deploy osd create host：/ dev / xvdb1：/ dev / xvdb2 host：/ dev / xvdf1：/ dev / xvdf2

此外，当您手动创建这些分区时，您需要将设备的所有权更改为ceph：ceph以使ceph-deploy工作。示例：chown ceph：ceph / dev / xvdb * 示例：chown ceph：ceph / dev / xvdf *

注意：如果你没有指定日志磁盘，即[/ dev / xvdb2或/ dev / xvdf2]，ceph-deploy将使用文件而不是磁盘分区来存储日志。
