What does this mean for 2.4.x and 2.5.x?
Originally 2.4.x was supposed to be the version that would be supported for a long
persiod, then 2.5.x became that version because of HFS as far as I understand.

This major release includes new features:
MDT-OST Consistency Check and Repair (LFSCK Phase 2)- Allows the MDS to verify the
consistency of a Lustre filesystem while it is mounted and in use. The latest enhancements
are to check and repair the validity of OST objects of regular files and to identify and
optionally remove or link into lost+found OST objects that are not referenced by any files
on the MDS. This development is funded by OpenSFS
Single Client Performance Improvements – Single thread per process IO performance has been
improved. This work was discussed in details at
Striped Directories -Enables a single directory to be striped across multiple MDTs to
improve single directory performance and scalability. This is a technology preview of part
of the DNE phase 2 work funded by OpenSFS that will be fully available in a future Lustre
Fuller details can be found in the change
;, the scope
and the test
The following are known issues in the Lustre 2.6 Release:
- A rare race condition can lead
to an LASSERT when unmounting an OST.
- Empty access control lists
(ACLs) will be stored for copied files when using a ZFS MDS. It does not affect ldiskfs
LU-4367 -<https://jira.hpdd.intel.com/browse/LU-4367> Metadata performance is
affected for unlinking files in a single shared directory in a manner common with mdtest
- DNE configurations with
multiple MDTs sharing a single node with an MGS may hang during MDT mount or fail to mount
an MDT after unclean shutdown.
Work is in progress for these issues.
NOTE: Users should note that usage of the e2fsprogs-based lfsck has been deprecated and
replaced by "lctl lfsck_start”. Using older e2fsprogs-based lfsck may lead to
filesystem corruption. Once available, it is also recommended to use e2fsprogs-1.42.11.wc2
Please log any issues found in the issue tracking
We would like to thank OpenSFS<http://www.opensfs.org/>
