Ceph：挂载失败：域外的数值参数

Question

由于this的问题，我的朋友找到了包含ceph的Open Fusion repo。

ceph-fuse 安装没有问题：

# ceph -v
ceph version 0.27.1 (commit:44900d4c13f02913b3347cac3e1dc33632d5b8ff)
You have new mail in /var/spool/mail/root

但我在挂载时遇到以下错误：

# cfuse -m 192.168.2.13:6789 /mnt/ceph/

有人熟悉 Ceph 吗？我现在能做什么？

Answer 1

首先，这是一个古老的 ceph 版本（0.60.0 刚刚发布，0.56.4 是当前的稳定版本）。

如果您实际上没有设置 Ceph 集群，我猜想虽然可能安装了软件包，但集群实际上并不能正常工作。我会看一下“ceph -s”，看看您是否收到“健康正常”类型的消息。
