-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-This is a bugfix release over 3.1, which was withdrawn due to serious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.
