I were not able to restart them via systemd. I then found that even tcmu-runner is not running and it exits with the following error: > > > > ### > > > tcmu_rbd_check_image_size:827 rbd/production.lun1: Mismatched sizes.

It sounds like you are potentially hitting [1]. The ceph-iscsi-config library thinks your image size is 5TiB but you actually have a 5121GiB (~5.001TiB) RBD image. Any clue how your RBD image got to be 1GiB larger than an even 5TiB? > > > > The following packets are installed: > > > rpm -qa |egrep "ceph|iscsi|tcmu|rst|kernel" > > > libtcmu-1.4.0-106.gd17d24e.el7.x86_64 > > ceph-iscsi-cli-2.7-2.7.el7.noarch > > kernel-3.10.0-957.5.1.el7.x86_64 > > ceph-base-13.2.5-0.el7.x86_64 > > ceph-iscsi-config-2.6-2.6.el7.noarch > > ceph-common-13.2.5-0.el7.x86_64 > > ceph-selinux-13.2.5-0.el7.x86_64 > > kernel-tools-libs-3.10.0-957.5.1.el7.x86_64 > > python-cephfs-13.2.5-0.el7.x86_64 > > ceph-osd-13.2.5-0.el7.x86_64 > > kernel-headers-3.10.0-957.5.1.el7.x86_64 > > kernel-tools-3.10.0-957.5.1.el7.x86_64 > > kernel-3.10.0-957.1.3.el7.x86_64 > > libcephfs2-13.2.5-0.el7.x86_64 > > kernel-3.10.0-862.14.4.el7.x86_64 > > tcmu-runner-1.4.0-106.gd17d24e.el7.x86_64 > > > > Thanks, > > Greets > > > Kilian > > > _______________________________________________ > ceph-users mailing list > ceph-users@xxxxxxxxxxxxxx > http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com [1] https://github.com/ceph/ceph-iscsi-config/pull/68 -- Jason _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
