@Mike
Did you have the chance to update download.ceph.com repositories for the new version?
I just tested the packages from shaman in our DEV environment and it seems to fix the work - after updating the packages i was not able to reproduce the error again and tcmu-runner starts up without any errors ;)

I have installed version: They are on shaman only right now: https://4.chacra.ceph.com/r/ceph-iscsi-config/master/24deeb206ed2354d44b0f33d7d26d475e1014f76/centos/7/flavors/default/noarch/ https://4.chacra.ceph.com/r/ceph-iscsi-cli/master/4802654a6963df6bf5f4a968782cfabfae835067/centos/7/flavors/default/noarch/ The shaman rpms above have one bug we just fixed in ceph-iscsi-config where if DNS is not setup correctly gwcli commands can take minutes. I am going to try and get download.ceph.com updated. > > ceph-iscsi-config-2.6-2.6.el7.noarch > ------------------------------------------------------------------------ > *Von:* ceph-users <ceph-users-bounces@xxxxxxxxxxxxxx> im Auftrag von > Kilian Ries <mail@xxxxxxxxxxxxxx> > *Gesendet:* Mittwoch, 2.

Cluster was setup via ceph-ansible v3.2-stable. I just checked my nodes and saw that only two of the four configured iscsi gw nodes are working correct.
