The pool that was removed did have iscsi images in it. I removed and rebuild config.

This still seems like a current issue. [root@NAS-AUSYD-RK4-CEPHMON2 ~]# gwcli /disks> ls o- disks .........................................................................................................

A little bit more info... Running - tcmu-runner-1.3.0-89.g7d0023e.el7.x86_64 When the lockup occurs you can't run systemctl restart tcmu-runner as it never returns. I believe that is what is preventing reboot...

Also noted that I am running the Centos 7.5 standard install of targetcli. Its version is slightly lower then the requirements on the ceph master docs. Do you think this...

Ok, that sounds good. If you want me to test it - I can. It seems that both iscsi nodes crash every few days.

and yes - Centos 7.5 with latest updates.

Did this get merged?

Seems the latest Centos patches helped. No more crashes.
