General Support Statement

The following definitions apply:

L1: Installation and problem determination - technical support designed to provide compatibility information, installation and configuration assistance, usage support, on-going maintenance and basic troubleshooting. Level 1 Support is not intended to correct product defect errors.
L2: Reproduction of problem isolation - technical support designed to duplicate customer problems, isolate problem areas and potential issues, and provide resolution for problems not resolved by Level 1 Support.
L3: Code Debugging and problem resolution - technical support designed to resolve complex problems by engaging engineering in patch provision, resolution of product defects which have been identified by Level 2 Support.

3 New Features and Known Issues #

3.1 civetweb on Ports 80/443 #

Ceph Hammer provides an embedded web server, civetweb, for the Rados Gateway. When run as user root, it can bind to ports lower than 1024 (namely ports 80 and 443 for HTTP and HTTPS, respectively), but SES 2 also supports Apache-based deployments, which require that the Rados Gateway be operated as user wwwrun and group www. When run as user wwwrun, the civetweb-based Rados Gateway cannot bind to port 80/443 due to insufficient privileges.

This issue is addressed in SES 2 by granting the cap_net_bind_service fs capability to the Rados Gateway binary, /usr/bin/radosgw .

3.2 RBD iSCSI Gateway Support #

Until now, Ceph storage has only been accessible from Ceph aware clients, such as the Linux kernel RADOS Block Device (RBD) module, or via the S3/SWIFT object storage APIs.

With SES 2, RADOS Block Devices can be exposed to remote hosts via the iSCSI protocol. iSCSI gateway nodes can be configured and managed within a Ceph cluster using the lrbd utility.

Any operating system with an iSCSI initiator, such as Microsoft Windows or VMware ESXi, can utilize RBD images on an SES 2 Ceph cluster as they would a local disk, by connecting to one or more iSCSI gateway nodes.

RBD images exposed via more than one iSCSI gateway can be accessed in a fault-tolerant fashion, allowing for failover between redundant iSCSI gateway paths.

3.3 Data at rest encryption #

Up to now it is only possible to store encryption keys on the disk.

With SES2 its possible to:

* Encrypt your OSD data/journal with either LUKS (Linux Unified Key Setup) or plain dm-crypt.

* Store your encryption key on a dedicated FTPS server and retrieve it from same.
