@Mike Did you have the chance to update download.ceph.com repositories for the new version?

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@lists.ceph.com > 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@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
[ceph-users] tcmu-runner: mismatched sizes for rbd image size
Hi, i'm running a ceph mimic cluster with 4x ISCSI gateway nodes. Cluster was setup via ceph-ansible v3.2-stable. I just checked my nodes and saw that only two of the four configured iscsi gw nodes are working correct. I first noticed via gwcli: ### $gwcli -d ls Traceback (most recent call last): File "/usr/bin/gwcli", line 191, in main() File "/usr/bin/gwcli", line 103, in main root_node.refresh() File "/usr/lib/python2.7/site-packages/gwcli/gateway.py", line 87, in refresh raise GatewayError gwcli.utils.GatewayError ### I investigated and noticed that both "rbd-target-api" and "rbd-target-gw" are not running. 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. RBD image size 5498631880704. Requested new size 5497558138880. ### Now i have the situation that two nodes are running correct and two cant start tcmu-runner. I don't know where the image size mismatches are coming from - i haven't configured or resized any of the images. Is there any chance to get my two iscsi gw nodes back working?
