Description Anping Li 2015-10-27 03:11:28 EDT
Description of problem:
Ceph-common is ceph the server package. ceph-fuse packages must be installed, without this package, the ceph volume can be mounted. 

If ansible can't install ceph-fuse, it should report a message at the end.

Version-Release number of selected component (if applicable):
ansible pull request 738

How reproducible:

Steps to Reproduce:
1. install openshift by ansible
2. check the ceph packages after installation
3. mount ceph volume, it report wrong fs type.

Actual results:

1. ceph-common-0.80.7-3.el7.x86_64 was installed

2. Mount failed:
# mount -t ceph /mnt -o name=admin,secretfile=ceph.key
mount: wrong fs type, bad option, bad superblock on,
       missing codepage or helper program, or other error

       In some cases useful info is found in syslog - try
       dmesg | tail or so.

Expect results:
The package "ceph-fuse.x86_64 : Ceph fuse-based client" should be installed.
Comment 1 Jason DeTiberus 2015-10-27 10:36:30 EDT
The storage plugin does not use the ceph fuse client, rather it uses the ceph kernel module, libraries and tools provided by ceph-common.

kubernetes docs for ceph rbd volume plugin: https://github.com/kubernetes/kubernetes/tree/master/examples/rbd

PR for the origin repo with examples for the ceph volume plugin: https://github.com/openshift/origin/pull/4772

To test mounting a volume, you will need to use the rbd map command:
rbd map <volume> --pool <pool> -m <ceph monitor host> --key=<admin user's key>

The rbd command will return the name of a block device that can then be mounted (generally /dev/rbd0 for the first device and incrementing for additional mounts).
