rook-ceph-osd-prepare pod卡住数小时

Question

我是个新手，使用rook在k8s集群中安装ceph。我看到pod rook-ceph-osd-prepare永远处于运行状态，并停留在下面的行上：

2020-06-15 20:09:02.260379 D | exec: Running command: ceph auth get-or-create-key 
client.bootstrap-osd mon allow profile bootstrap-osd --connect-timeout=15 --cluster=rook-ceph 
--conf=/var/lib/rook/rook-ceph/rook-ceph.config 
--name=client.admin --keyring=/var/lib/rook/rook-ceph/client.admin.keyring 
--format json --out-file /tmp/180401029

当我登录到container并运行相同的命令时，我看到它也卡住了，并且在按^C之后，它显示如下：

Traceback (most recent call last):
  File "/usr/bin/ceph", line 1266, in <module>
    retval = main()
  File "/usr/bin/ceph", line 1197, in main
    verbose)
  File "/usr/bin/ceph", line 622, in new_style_command
    ret, outbuf, outs = do_command(parsed_args, target, cmdargs, sigdict, inbuf, verbose)
  File "/usr/bin/ceph", line 596, in do_command
    return ret, '', ''

请让我知道，如果有人有任何提示来解决这个问题或解决这个问题？

Answer 1

在我的例子中，问题是我的Kubernetes主机不在相同的内核版本中。

一旦我升级了内核版本以与所有其他节点匹配，这个问题就解决了。

Answer 2

在我的例子中，我的一个节点的系统时钟与硬件不同步，因此节点之间存在时间差距。

也许你应该检查timedatectl命令的输出。
