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

[Shay Katz]

Hi

I have client (centos 7) with logged in sessions,

 

[root@lgdrm1027 ~]# iscsiadm -m session

tcp: [1] 10.206.12.5:3260,1 iqn.2008-05.com.xtremio:001e679efc4a (non-flash)

tcp: [8] 10.205.12.16:3260,1 iqn.2008-05.com.xtremio:001e679efff7 (non-flash)

 

After logging in the user remove the portals from the target, now when I am trying to logged out the operation fails

And I didn't find how to remove them (There is no force flag):

 

[root@lgdrm1027 ~]# iscsiadm -m node -u

[root@lgdrm1027 ~]#

same scenario on centos 6.5 worked well.

Could you attach your /var/log/messages for when you removed the portals and when you ran the logout command?

Hi,

during the last week i have tried to reproduce the problem without success.

I guess it is false alarm.

Shay

[Michael Christie]

Thanks for reporting back.

If this happens again, give us the /var/log/messages and the output of

iscsiadm -m session -P 3

when the iscsiadm ….. —logout command is returning the errors you pasted below.

[seanm...@gmail.com]

I am seeing this issue, and can't figure out how to clear the session.

From Journal open-iscsi, One problem is that 192.168.1.210 was reassigned to 192.168.1.115, but still persist in iscsid somehow.

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.
