Features that are currently being developed for future Lustre releases in the Lustre community. These will be eligible for inclusion in future Lustre releases as per the defined processes. Features are not listed in priority or landing order.  Projects not currently under development, or ideas for features, should be listed on the Project Ideas page.
 
Please note that the targeted release information is provided by the developing organization for informational purposes only and is in no way a roadmap commitment until it appears on the roadmap.

|-
| Patchless Server || Remove Lustre kernel patches to allow Lustre servers to be more easily ported to new kernels, and to be built against vendor kernels without changing the vendor kernel RPMs || Intel || [https://jira.hpdd.intel.com/browse/LU-20 LU-20] || 2.5 || .
|-
| End-to-End Data Integrity with T10 || Add a path to pass T10 Protection Information from Lustre clients through to server disks || Xyratex|| [https://jira.hpdd.intel.com/browse/LU-2488 LU-2488] [https://jira.hpdd.intel.com/browse/LU-2584 LU-2584] || 2.6 || .

|-
| HSM - Release || Release action discard all data from a Lustre file, mainly by removing all associated OST objects, and flags it as released (in LMA). This is used when a file has been successfully copied in an external storage, a HSM || CEA || [https://jira.hpdd.intel.com/browse/LU-1333 LU-549] || 2.5 || .
|-
| LFSCK Phase 2 - MDT-OST consistency || Traverse all inodes in an MDT and verify their corresponding objects on the OSTs exist. This work is part of the OpenSFS contract awarded to Whamcloud. LFSCK Architecture and Design Docs available soon || Intel || [https://jira.hpdd.intel.com/browse/LU-957 LU-957] || 2.5 || .
|-
| LFSCK Phase 3 - DNE consistency || Enhance LFSCK to work with DNE filesystems, including remote directory entries, and OST orphan handling for multiple MDTs || Intel || [https://jira.hpdd.intel.com/browse/LU-2307 LU-2307] || 2.6 || .
|-
| client-server shared modules cleanup || Clean up Lustre client to facilitate pushing it into upstream Linux kernel. Need to split some server code dependencies from client to avoidmaking extensive server code changes || EMC || [https://jira.hpdd.intel.com/browse/LU-1214 LU-1214] [https://jira.hpdd.intel.com/browse/LU-1330 LU-1330] || . || .

|-
| HSM - Coordinator || Today Coordinator runs in the MDT layer, code need to be reorganized to achieve a better layering MDT/MDD so some changes can be made in a single transaction || CEA || [https://jira.hpdd.intel.com/browse/LU-2061 LU-2061] || 2.5 || .
|-
| HSM - Copy tool || The copy tool is the HSM component which moves data between Lustre and an external storage system. This feature will be for POSIX copy tool which can use any POSIX-compliant filesystem as a backend target system. The copy tool is used for all the sanity tests made for HSM features (sanity-hem.sh) || CEA || [https://jira.hpdd.intel.com/browse/LU-2062 LU-2062] || 2.5 || .

|-
| Replication Phase 1 || Solution Architecture and HDL, Exclusive Open, RAID 1 Layout, Layout Modification Method, Read Only RAID 1 || Intel || . || 2.5 || .
|-
| LNET Router Priorities || Adds a parameter to route module parameters which sets a priority number for that route. Routes with the smallest priority number will be favored over ones with larger numbers || Intel || LU-2934 || 2.5 || .
|-
| LNET: Read Routing List from File || Introduces a user space script which will read routes from a config file and add those routes to Lnet dynamically with the lctl utility. This allows the support of very large routing tables || Intel || LU-2950 || 2.5|| .
|-
| Reduce ldlm_poold Execution Time || . || Intel || . || 2.5 || .
|-
| Endianness Fixes || Fixes endian and byte-alignment issues in the Lustre codebase. Platforms under consideration for this project are x86 vs Sparc || Intel || . || 2.5 || .
|-
| errno Translation Tables || Add addition of errno translations between architectures with different errno definitions || Intel || LU-2743 || 2.5 || .
