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_St... 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. -- Alexander E. Patrakov
