Good morning,
I wanted to inquire about the status of the Ceph iSCSI gateway service. We
currently have several machines installed with this technology that are working
correctly,
although I have seen that it appears to be discontinued since 2022. My question
is whether to continue down th
I was reading on the Ceph site that iSCSI is no longer under active development
since November 2022. Why is that?

Hi All,
Just successfully(?) completed a "live" update of the first node of a
Ceph Quincy cluster from RL8 to RL9. Everything "seems" to be working -
EXCEPT the iSCSI Gateway on that box.
During the update the ceph-iscsi package was removed (ie
`ceph-iscsi-3.6-2.g97f5b02.el8.noarch.rpm` - th

I am looking at using an iscsi gateway in front of a ceph setup. However
the warning in the docs is concerning:
The iSCSI gateway is in maintenance as of November 2022. This means that
it is no longer in active development and will not be updated to add new
features.
Does this mean I should

Hi guys,
we are using ceph-iscsi to provide block storage for Microsoft Exchange and
vmware vsphere. Ceph docs state that you need to configure Windows iSCSI
Initatior for fail-over-only but there is no such point for vmware. In my
tcmu-runner logs on both ceph-iscsi gateways I see the followin
Hi Everybody (Hi Dr. Nick),
I'm attacking this issue from both ends (ie from the Ceph-end and from
the oVirt-end - I've posted questions on both mailing lists to ensure we
capture the required knowledge-bearer(s)).
We've got a Ceph Cluster set up with three iSCSI Gateways configured,

Hi All,
I've followed the instructions on the CEPH Doco website on Configuring
the iSCSI Target. Everything went AOK up to the point where I try to
start the rbd-target-api service, which fails (the rbd-target-gw service
started OK).
A `systemctl status rbd-target-api` gives:

Hi Guys.
I have a doubt about CEPH working with iSCSI Gateways.
Today we have a cluster with 10 OSD Nodes, 3 Monitors and 02 iSCSI Gateways. We
are planning to expand de gateways up to 04 machines. We understood the process
to do this, but we would like to know if it's necessary to adjust some

Hi All,
I2d like to install a Ceph Nautilus on Ubuntu 18.04 LTS and give the storage to
2 windows server via ISCSI. I choose the Nautilus because of the deploy
function I don't want to another VM to cephadm. So I can isntall the ceph and
it is working properly but can't setup the icsi gateway.
I have an issue on ceph-iscsi ( ubuntu 20 LTS and Ceph 15.2.6) after I
restart rbd-target-api, it fails and not starting again:

I've finally gotten around to setting up iSCSI gateways on my primary
production cluster, and performance is terrible.
We're talking 1/4 to 1/3 of our current solution.
I see no evidence of network congestion on any involved network link. I see no
evidence CPU or memory being a problem o
Hi,
does anyone here use CEPH iSCSI with VMware ESXi? It seems that we are hitting
the 5 second timeout limit on software HBA in ESXi. It appears whenever there
is increased load on the cluster, like deep scrub or rebalance. Is it normal
behaviour in production? Or is there something special we
Dear All,
a week ago we had to reboot our ESXi nodes since our CEPH cluster sudennly
stopped serving all I/O. We have identified a VM (vCenter appliance) which was
swapping heavily and causing heavy load. However, since then we are
experiencing strange issues, as if the cluster cannot handle an

We've used iSCSI to support virtualization for a while, and have used
multi-pathing almost the entire time. Now, I'm looking to move from our single
box iSCSI hosts to iSCSI on Ceph.
We have 2 independent, non-routed, subnets assigned to iSCSI (let's call them

Is it possible to create an EC backed RBD via ceph-iscsi tools (gwcli,
rbd-target-api)? It appears that a pre-existing RBD created with the rbd
command can be imported, but there is no means to directly create an EC
backed RBD. The API seems to expect a single pool field in the body to work
with.
Hi,
In the Documentation on
https://docs.ceph.com/docs/nautilus/rbd/iscsi-target-cli/ it is stated
that you need at least CentOS 7.5 with at least kernel 4.16 and to
install tcmu-runner and ceph-iscsi "from your Linux distribution's
software repository".
CentOS does not know about tcmu-runner nor
