DNE Phase IIb |
Asynchronous Commit of cross-MDT updates for improved performance. Remote rename and remote hard link functionality. |
Richard Henwood (Intel) |
LU-3534 |
2015-05
|
UID/GID mapping |
Map UID/GID for remote client nodes to local UID/GID on the MDS and OSS. Allows a single Lustre filesystem to be shared across clients with administrative domains. |
Stephen Simms (Indiana University) |
LU-3291 |
2015-05
|
Shared Key Crypto |
Allow node authentication and/or RPC encryption using symmetric shared key crypto with GSSAPI. Avoids complexity in configuring Kerberos across multiple domains. |
Stephen Simms (Indiana University) |
LU-3289 |
2015-11
|
NRS Delay |
Use NRS for fault injection. Intentionally delay request processing to simulate server load. |
Chris Horn (Cray) |
LU-6283 |
2015-04
|
Multiple modify RPCs |
Support of multiple slots per client (in last_rcvd file) for reply reconstruction of filesystem-modifying requests. Will improve the metadata operations performance of a single client |

|
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. |
Andreas Dilger (Intel) |
LU-20
|
End-to-End Data Integrity with T10 |
Add a path to pass T10 Protection Information from Lustre clients through to server disks to reduce CPU overhead of multiple checksum calculations. |
? (Seagate) |
LU-2584
|
Layout Enhancement |
Add support for multiple layouts on a single file, for File Level Replication, Data on MDT, extent-based layouts, etc. |
John Hammond (Intel) |
LU-3480
|
ZFS ZIL Support |
Add support for the ZFS Intent Log (ZIL) to the Lustre osd-zfs |
Alex Zhuravlev (Intel) |
LU-4009
|
File Level Replication Phase 1 |
Solution Architecture and HDL, Exclusive Open, RAID 1 Layout, Layout Modification Method, Read Only RAID 1 |
Jinshan Xiong (Intel) |
LU-3254
|
File Level Replication Phase 2 |
Immediate asynchronous write from client. |
Jinshan Xiong (Intel) |
LU-3254
|
Data on MDT |
Allow small files to be stored directly on the MDT for reduced RPC count and improved performance. |
? (Intel) |
.
|
Quota for Projects |
Allow specifying a "project" or "subtree" identifier for files for accounting to a project, separate from UID/GID. |
Shuichi Ihara (DDN) |
LU-4017
|
Large Bulk IO |
Increase the OST bulk IO maximum size to 16MB or larger for more efficient disk IO submission. |
Shuichi Ihara (DDN) |
.
|
Kerberos Revival |
Fix up existing Kerberos code so it is tested working again. |
Sébastien Buisson (Bull/Atos) |
LU-6356
|
Lock ahead |
Allow user space to request LDLM extent locks in advance of need. Intended to optimize shared file IO. |

Dynamic LNET Config |
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 |
