Hi Mike,
I am facing a similar issue.
[r...@maverick iscsi]# service iscsid stop
Not stopping iscsid: iscsi sessions still active [WARNING]
Ok, so we have an active iscsi session.
[r...@maverick iscsi]# iscsiadm -m session

[r...@maverick iscsi]# iscsiadm -m session --sid=10 --op=delete
iscsiadm: This command will remove the record [iface: default, target:

then rerun command to remove record.

[r...@maverick iscsi]# iscsiadm -m node --logoutall=all
Logging out of session [sid: 10, target: iqn.

But ...

sdb is not mounted anywhere.
[r...@maverick iscsi]# fdisk -l | grep sdb
fdisk can't see sdb.

Interesting ... don't know what's going on.
Mike, can you help out here.
Thanks,
