Public bug reported:
1. these commands worked well with open-iscsi on ubuntu-trusty:
/:/etc/init# /etc/init.d/open-iscsi restart
/:/etc/init# iscsiadm -m discovery -t sendtargets -p {portal_ip}
2. But when I failed to re-run these commands on ubuntu-xenial:
/:/etc/init# iscsiadm -m discovery -t sendtargets -p {portal_ip}
iscsiadm: Login failed to authenticate with target
iscsiadm: discovery login to {portal_ip} rejected: initiator failed
authorization
iscsiadm: Could not perform SendTargets discovery: iSCSI login failed due to
authorization failure
/:/etc/init# /etc/init.d/open-iscsi restart
[ ok ] Restarting open-iscsi (via systemctl): open-iscsi.service.
/:/etc/init# iscsiadm -m discovery -t sendtargets -p {portal_ip}
iscsiadm: Login failed to authenticate with target
iscsiadm: discovery login to {portal_ip} rejected: initiator failed
authorization
iscsiadm: Could not perform SendTargets discovery: iSCSI login failed due to
authorization failure
/:/etc/init# iscsiadm -m discovery -t sendtargets -p {portal_ip}
iscsiadm: Login failed to authenticate with target
iscsiadm: discovery login to {portal_ip} rejected: initiator failed
authorization
iscsiadm: Could not perform SendTargets discovery: iSCSI login failed
due to authorization failure
3. So I try to use "service" to restart "iscsid" on xenial and it was
worked.
/:/etc/init# service iscsid restart
/:/etc/init# iscsiadm -m discovery -t sendtargets -p {portal_ip}
{portal_ip}:3260,1041 iqn.1992-08.com.netapp:stflon0201
{portal_ip}:3260,1042 iqn.1992-08.com.netapp:stflon0201
Conclusion:
And open-iscsi is installed by "apt-get" and I knew these was twoo packages on
different distrs. And trusty didn't have "iscsid" service. Did I miss anything?
What is a compatible way to setup iscsi disks?
I found these are two services: open-iscsi and iscsid
On trusty, open-iscsi is 'Starts and stops the iSCSI initiator services
and logs into default targets'. But open-iscsi is 'Login to default
iSCSI targets at boot and log out of all iSCSI targets at shutdown' on
xenial. However, iscsid is 'The iSCSI initiator daemon takes care of
monitoring iSCSI connections to targets. It is also the daemon providing
the interface for the iscisadm tool to talk to when administering iSCSI
connections.' on xenial.
Could we set same service name to maintain open-iscsi functionality?
