I’m trying to create my first ceph disk from a client named bjorn :
[ceph@bjorn ~]$ rbd create foo --size 512000 -m helga -k /etc/ceph/ceph.client.admin.keyring
[ceph@bjorn ~]$ sudo rbd map foo --pool pool_ulr_1 --name client.admin -m helga.univ-lr.fr -k /etc/ceph/ceph.client.admin.keyring
rbd: sysfs write failed
rbd: map failed: (2) No such file or directory
Can you help me to find the problem ?
[ceph@bjorn ~]$ ceph -v
