Re: Could not logout of all requested sessions when working with centos 7

[soruk42]

Hi,

I ran into this same problem (and found this thread while googling for it), 
and compared CentOS 6 and 7 settings.

The fix, for me, was to edit /etc/iscsi/iscsid.conf and change the line

iscsid.safe_logout = Yes

... to = No

Then: systemctl restart iscsid.service

After that, the logout worked. (And, multipath did the right thing!)

Optionally, put the setting back to "Yes" afterwards and restart iscsid 
again.

Okay, I will correct it in V4.
