Subject: ANNOUNCE: mdadm 3.1.1 - A tool for managing Soft RAID under Linux
|
||||
|
||||
I am pleased to announce the availability of
|
||||
mdadm version 3.1.1
|
||||
|
||||
It is available at the usual places:
|
||||
countrycode=xx.
|
||||
http://www.${countrycode}kernel.org/pub/linux/utils/raid/mdadm/
|
||||
and via git at
|
||||
git://neil.brown.name/mdadm
|
||||
http://neil.brown.name/git?p=mdadm
|
||||
|
||||
This is a bugfix release over 3.1, which was withdrawn due to serious
|
||||
bugs. So it might be best to ignore 3.1 and say that this is a significant
|
||||
feature release over 3.0.x
|
||||
|
||||
Significant changes are:
|
||||
- RAID level conversion between RAID1, RAID5, and RAID6 are
|
||||
possible were the kernel supports it (2.6.32 at least)
|
||||
- online chunksize and layout changing for RAID5 and RAID6
|
||||
where the kernel supports it.
|
||||
- reduce the number of devices in a RAID4/5/6 array.
|
||||
|
||||
- The default metadata is not v1.1. This metadata is stored at the
|
||||
start of the device so is safer in many ways but could interfere with
|
||||
boot loaded. The old default (0.90) is still available and fully
|
||||
supported.
|
||||
|
||||
- The default chunksize is now 512K rather than 64K. This seems more
|
||||
appropriate for modern devices.
|
||||
|
||||
- The default bitmap chunksize for internal bitmaps is now at least
|
||||
64Meg as fine grained bitmaps tend to impact performance more for
|
||||
little extra gain.
|
||||
|
||||
This release is believed to be stable and you should feel free to
|
||||
upgrade to 3.1.1.

Changes Prior to release 3.1.1
|
||||
- Multiple fixes for new --grow levels including fixes for
|
||||
serious data corruption problems.
|
||||
- Change default metadata to v1.1
|
||||
- Change default chunk size to 512K
|
||||
- Change default bitmap chunk size to 64Meg
|
||||
- When --re-add is used, don't fall back to
|
||||
--add if --re-add fails as this can destroy data.
|
||||
|
||||
Changes Prior to release 3.1
|
||||
- Support --grow to change the layout of RAID4/5/6
|
||||
- Support --grow to change the chunksize of raid 4/5/6
