Hi all, we've a running drbd - iscsi cluster (two nodes Debian stretch, pacemaker / corosync, res group w/ ip + iscsitarget/lio-t + iscsiluns + lvm etc. on top of drbd etc.). Everything is running fine - but we didn't manage to get CHAP to work. targetcli / lio-t always switches the authentication off after a migration or restart.
I found the following lines in the iSCSITarget resource file (Debian stretch /usr/lib/ocf/resource.d/heartbeat/iSCSITarget, also in https://github.com/ClusterLabs/resource-agents/blob/master/heartbeat/iSCSITarget.in): [...] # TODO: add CHAP authentication support when it gets added back into LIO ocf_run targetcli /iscsi/${OCF_RESKEY_iqn}/tpg1/ set attribute authentication=0 || exit $OCF_ERR_GENERIC [...] (l384ff on github). This targetcli command actually disables authentication...but why? Is the assumption "LIO does not offer CHAP support" still true? Anybody out there who is successfully using lio-t + iSCSITarget + CHAP? Any hint is welcome!
