Description of problem:
======================
https://doc-stage.usersys.redhat.com/documentation/en/red-hat-ceph-storage/2/single/block-device-guide/#configuring_mirroring


 4.4. Configuring Mirroring -  'Configuring Pool Mirroring' step 2

ceph auth get-or-create client.local mon 'allow r' osd 'allow class-read object_prefix rbd_children, allow rwx pool=data' -o /etc/ceph/local.client.local.keyring --cluster local


ceph auth get-or-create client.remote mon 'allow r' osd 'allow class-read object_prefix rbd_children, allow rwx pool=data' -o /etc/ceph/remote.client.remote.keyring --cluster remote

should be

ceph auth get-or-create client.local mon 'allow r' osd 'allow class-read object_prefix rbd_children, allow pool data rwx' -o /etc/ceph/local.client.local.keyring --cluster local


ceph auth get-or-create client.remote mon 'allow r' osd 'allow class-read object_prefix rbd_children, allow pool data rwx' -o /etc/ceph/remote.client.remote.keyring --cluster remote


( change "allow rwx pool=data" to  "allow pool data rwx")

Additional info:
================
syntax mentioned in example is not throwing any error but later it is not syncing images from data pool

changed suggested works fine and able to sync images
