Hi,
Only now have I been able to act on this problem. My environment is
relatively simple: I have two ESXi 6.7 hosts, connected to two ISCSI
gateways, using two RBD images.
When this mail started, the workaround was to keep only one ISCSI gateway
connected, so it works normally. After the answer that received here that
the problem could be in the configuration of VMWare, I reviewed the
configuration of both (they are exactly according to Ceph documentation),
and rebooted both.
It turns out, now the gateway "ceph-iscsi1" is working. When I turn on
"ceph-iscsi2" it appears as "Active / Not optimized" for the two RBD
images
(before was an Active / Optimized for each image), and if I turn off
"ceph-iscsi1" it (ceph-iscs2) remains as "Active / No optimized "and
images
are unavailable.
Nothing is recorded in the logs. Can you help me?

In addition: I turned off one of the GWs, and
with just one it works
fine. When the two go up, one of the images is changing the "active /
optimized" all time (where generates the logs above) and everything is
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
