Open-iSCSI - Autologin seems not working

Hi,
I want to  add and mount an iscsi device autmatiocly after boot up. (but not the rootfs on the iscsi)

Manual login works well, but not the automatic one. And I can't see why.

node.startup and node.conn[0].startup is set to automatic, and iscsid.service is enabled and active.


node config

I always need to run something like
sudo iscsiadm -m node --targetname=iqn.2004-04.com.qnap:ts-253b:iscsi.neustadt.2d899e -p 10.10.12.39 -l
or
sudo iscsiadm -m node --targetname=iqn.2004-04.com.qnap:ts-253b:iscsi.neustadt.2d899e -p 10.10.12.39 --loginall=automatic` , so its look the correct files are read and the problem is anythere else.

Can anybody give me a hint or an explanation? Thanks a lot!

Re: Open-iSCSI - Autologin seems not working

For autologin you need iscsi.service to be enabled too - note missing 'd' smile
