1 | Subject: ANNOUNCE: mdadm 2.0 - A tool for managing Soft RAID under Linux |
2 | ||
3 | I am (at last) please to announce the availability of | |
4 | mdadm version 2.0 | |
5 | ||
6 | It is available at the usual places: | |
7 | http://www.cse.unsw.edu.au/~neilb/source/mdadm/ | |
8 | and | |
9 | http://www.{countrycode}.kernel.org/pub/linux/utils/raid/mdadm/ | |
10 | ||
11 | mdadm is a tool for creating, managing and monitoring | |
12 | device arrays using the "md" driver in Linux, also | |
13 | known as Software RAID arrays. | |
14 | ||
15 | Release 2.0 contains a substantial rewrite of various pieces of | |
16 | functionality, particularly the --create option. This enables support | |
17 | for a new style of superblock - the version-1 superblock. | |
18 | Version-1 can support many more than 28 devices and can be easily | |
19 | moved between hosts with different endian-ness. | |
20 | Release 2.0 also contains support for the recent bitmap-intent-logging | |
21 | which will appear in 2.6.13, and the RAID1 write-behind that will be | |
63f8c4c7 | 22 | available in 2.6.14 (it is currently only in -mm). |

24 | This release comes with a test-suite which has been used to verify that | |
25 | mdadm-2.0 actually works in a number of common scenarios. Some of the | |
26 | tests require a bleeding-edge kernel, so don't be surprised if some fail | |
27 | on kernels prior to 2.6.14. | |
28 | ||
29 | Being a '.0' release, 2.0 should be treated with some caution. | |
30 | However I believe it is quite stable and can safely be used on | |
31 | production systems. | |

33 | Note that this release is "2.0", not "2.0.0". I never found a use for |
34 | the third number with 1.X.Y, so I dropped it. | |

37 | Development of mdadm has moved from CSE@UNSW and is now sponsored by | |
38 | SUSE Labs, Novell Inc. | |
