| Subject: ANNOUNCE: mdadm 3.1 - A tool for managing Soft RAID under Linux |
| |
| Hot on the heals of 3.0.3 I am pleased to announce the availability of |
| mdadm version 3.1 |
| |
| 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 |
| |
| |
| It contains significant feature enhancements over 3.0.x |
| |
| The brief change log is: |
| - Support --grow to change the layout of RAID4/5/6 |
| - Support --grow to change the chunksize of raid 4/5/6 |
| - Support --grow to change level from RAID1 -> RAID5 -> RAID6 and |
| back. |
| - Support --grow to reduce the number of devices in RAID4/5/6. |
| - Support restart of these grow options which assembling an array |
| which is partially grown. |
| - Assorted tests of this code, and of different RAID6 layouts. |
| |
| Note that a 2.6.31 or later is needed to have access to these. |
| Reducing devices in a RAID4/5/6 requires 2.6.32. |
| Changing RAID5 to RAID1 requires 2.6.33. |
| |
| You should only upgrade if you need to use, or which to test, these |
| features. |
