[ceph-users] Re: iSCSI Gateway reboots and permanent loss

I do not think it's going to do what you want when the node you want to delete is down. It looks like we only temporarily stop the gw from being exported. It does not update the gateway.cfg, because we do the config removal call on the node we want to delete. So gwcli would report success and the

Also, I do not think we saw if the ceph-iscsi versions are the same. We saw the ceph versions are different which is ok. If you were using a old ceph-iscsi version which has different settings/values with a newer version then you could see this error. On 12/03/2019 06:47 PM, Jason Dillaman wrote:

[ceph-users] Re: Starting service rbd-target-api fails

ave you used the pool before? Do you have some leftover auth/permissions that did not get setup on the gw nodes? If you are using ceph-iscsi 3 or newer, rename the pool back to iscsi or try a new one, and do: [config] pool = iscsi in /etc/ceph/iscsi-gateway.cfg on all gw nodes, does it start ok? >
