[cephfs-provisioner] - unable to provision claim

[SockenSalat]

when I try to provision the claim from the examples I get 'Warning' reason: 'ProvisioningFailed' failed to provision volume with StorageClass "cephfs": exit status 1. But folders matching the generic share name are created in the ceph-cluster.

env

centos 7
kubernetes 1.17.2
ceph-commons 2:12.2.13-0.el7

The problems was insuficcent permissions on the user

ceph auth get-or-create client.autoclaim mon 'allow rwx' mds 'allow rwp, allow rw path=/autoclaim/log' osd 'allow rwx pool=cephfs_data' did the trick and all works fine now.
