Can anyone confirm if the following message is a proof that this bug was triggered ?
May 13 15:56:31 osp1-compute04 kernel: strict_strtoul() failed for port_str: -22
This error has been noticed multiple times in the past but issue where 'nova-compute cannot login to iscsi' occurred only once .
I was able to recover this by adding acl in target :
/> cd /iscsi/iqn.2010-10.org.openstack:volume-3f344318-c12e-4d92-a87c-02c025e6915a/tpg1/acls/iqn.1994-05.com.redhat:95c3136ac590/
/iscsi/iqn.20...:95c3136ac590> get auth
There was no acl set.
I created acl & since no userid & password was set ,so i set it .
Check from /var/lib/iscsi/node/*/* file if node.session.auth variables on compute.
Use same information to set on targetcli .
Please update to latest version as that should be fixed with persistence and concurrency issues patches.
