Hello All,
I just installed ceph iscsi target following "manual installation" at
https://docs.ceph.com/docs/nautilus/rbd/iscsi-target-cli-manual-install/
When the api server starts it seems to work but in service status it
reports:
apr 30 07:22:51 lab-ceph-01 rbd-target-api[58740]: Processing osd blacklist
entries for this node

found

My configuration contains my hostname :
cat /etc/ceph/iscsi-gateway.cfg
[config]
# Name of the Ceph storage cluster. A suitable Ceph configuration file
allowing
# access to the Ceph storage cluster from the gateway node is required, if
not
# colocated on an OSD node.
cluster_name = ceph
# Place a copy of the ceph cluster's admin keyring in the gateway's
/etc/ceph
# drectory and reference the filename here
gateway_keyring = ceph.client.admin.keyring
# API settings.
# The API supports a number of options that allow you to tailor it to your
# local environment. If you want to run the API under https, you will need
to
# create cert/key files that are compatible for each iSCSI gateway node,
that is
# not locked to a specific node. SSL cert and key files *must* be called
# 'iscsi-gateway.crt' and 'iscsi-gateway.key' and placed in the
'/etc/ceph/' directory
# on *each* gateway node. With the SSL files in place, you can use
'api_secure = true'
# to switch to https mode.
debug = true
# To support the API, the bear minimum settings are:
api_secure = false
#prometheus_exporter = false
# Additional API configuration options are as follows, defaults shown.
# api_user = admin
# api_password = admin
# api_port = 5001
trusted_ip_list = lab-ceph-01
When I run gwcli command it reports:
[root@lab-ceph-01 ansible]# gwcli -d

I installed the same on different server 2 or 3 weeks ago and and it is
working,
Any change in the code in last weeks ?
Please, anyone could help me ?
