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 <module> 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?
The following packets are installed:
rpm -qa |egrep "ceph|iscsi|tcmu|rst|kernel"
