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 be wary of using it, or is it simply that it
does all the stuff it needs to and no further development is needed?
Hello Mark,
The planned replacement is based on the newer NVMe-oF protocol and
SPDK. See this presentation for the purported performance benefits:
https://ci.spdk.io/download/2022-virtual-forum-prc/D2_4_Yue_A_Performance_S…
The git repository is here: https://github.com/ceph/ceph-nvmeof.
However, this is not yet something recommended for a production-grade
setup. At the very least, wait until this subproject makes it into
Ceph documentation and becomes available as RPMs and DEBs.
For now, you can still use ceph-iscsi - assuming that you need it,
i.e. that raw RBD is not an option.
