[Bug 1009974] Re: "nova live-migration" fails silently

[Marcelo Dieder]

I have the same problem.

I changed the nova.conf:


--live_migration_uri=qemu+tcp://%s-x/system
--live_migration_flag=VIR_MIGRATE_UNDEFINE_SOURCE,VIR_MIGRATE_PEER2PEER, 
VIR_MIGRATE_TUNNELLED

and

nova live-migration bd8474bc-2c93-4df8-ae04-372f10471b96 cloud02

But nothing happens. In the logs I see that it passes the iptables rules
(new-network) but nothing else happens.

[Bug 922232] Re: Volumes fail to attach without discovery using tgt

[Marcelo Dieder]

I have the same problem. The fix its ok?

In version Essex (Ubuntu 12.04), i create a new node compute
(multinode), and add the volume to a instance.

I have the error in the node compute (/var/log/nova/nova-compute.log):

Stderr: 'iscsiadm: No portal found.\n', and manually:

# iscsiadm -m node -T iqn.2010-10.org.openstack:volume-0007 -p 
192.168.56.2:3260 --rescan
iscsiadm: No portal found.

But if i make a discovery...

root@cloud02:~# iscsiadm -m discovery -t st -p 192.168.56.2 
192.168.156.66:3260,1 iqn.2010-10.org.openstack:volume-0007
192.168.56.2:3260,1 iqn.2010-10.org.openstack:volume-0006
10.1.0.4:3260,1 iqn.2010-10.org.openstack:volume-0006
10.0.2.15:3260,1 iqn.2010-10.org.openstack:volume-0006
192.168.122.1:3260,1 iqn.2010-10.org.openstack:volume-0006
169.254.169.254:3260,1 iqn.2010-10.org.openstack:volume-0006
192.168.56.2:3260,1 iqn.2010-10.org.openstack:volume-0007
10.1.0.4:3260,1 iqn.2010-10.org.openstack:volume-0007
10.0.2.15:3260,1 iqn.2010-10.org.openstack:volume-0007
192.168.122.1:3260,1 iqn.2010-10.org.openstack:volume-0007
169.254.169.254:3260,1 iqn.2010-10.org.openstack:volume-0007

and then a login:

root@cloud02:~# iscsiadm -m node -T iqn.2010-10.org.openstack:volume-0007 
-p 192.168.56.2:3260 --login
Logging in to [iface: default, target: 
iqn.2010-10.org.openstack:volume-0007, portal: 192.168.56.2,3260]
Login to [iface: default, target: iqn.2010-10.org.openstack:volume-0007, 
portal: 192.168.56.2,3260]: successful

and rescan:

root@cloud02:~# iscsiadm -m node -T iqn.2010-10.org.openstack:volume-0007 
-p 192.168.56.2:3260 --rescan
Rescanning session [sid: 1, target: iqn.2010-10.org.openstack:volume-0007, 
portal: 192.168.56.2,3260]

and now the instance attached volume!

it seems that the activation of a new node login is not automatic?
