Re: 答复: 答复: tgt with ceph

This is probably a better question for a tgt mailing list at this point. From a quick glance, I don't see anything wrong with your config, but clearly the bsopts are not getting passed to the rbd driver. Do you see the "tgtd" process being started by tgt-admin with the "--bsopts" parameter?

Hi Jason,

Thank you. I'm checking this document and trying to fix the configuration.

This is my tgt configuration:

[root@datanode1 ~]# cat /etc/tgt/targets.conf 

# Empty targets configuration file -- please see the package

# documentation directory for an example.

#

# You can drop individual config snippets into /etc/tgt/conf.d

include /etc/tgt/conf.d/*.conf

<target iqn.2016-08.rbdstore.com:iscsi>  

    driver iscsi  

    bs-type rbd  

    backing-store iscsi/tgt

    bsopts "conf=/etc/ceph/ceph.conf;id=iscsiuser"

</target> 

This is my ceph configuration:

[root@datanode1 ~]# cat /etc/ceph/ceph.conf

[global]

osd crush location hook = /usr/bin/calamari-crush-location

osd_pool_default_pgp_num = 333

auth_service_required = cephx

osd_pool_default_size = 2

filestore_xattr_use_omap = true

osd_pool_default_min_size = 1

auth_client_required = cephx

osd_pool_default_pg_num = 333

auth_cluster_required = cephx

mon_host = 192.168.24.230

osd_journal_size = 1024

mon_initial_members = mysql230

osd_crush_chooseleaf_type = 1

fsid = fcb47f45-a2e2-4e02-a5f9-97bae9dac505

[client.iscsiuser]

id=iscsiuser

keyring=/etc/ceph/ceph.client.iscsiuser.keyring

And, when I restarted tgt, see these errors:

cat /var/log/messages

thanks for any advise.

I think you are looking for the "id" option -- not "name".
