fine. When the two go up, one of the images is changing the "active /

extremely slow.
Your multipathing in ESX is probably misconfigured and you have set it
up for active active, or one host can't see all the iscsi paths either
because it's not logged into all the sessions or because the network is
not up on one of the paths.
I'm using:
tcmu-runner-1.4
ceph-iscsi-3.3
ceph 13.2.7

Hi,
I am having an unusual slowdown using VMware with ISCSI gws. I have
two ISCSI gateways with two RBD images. I have checked the following
in the logs:
