4 | mdadm version 2.4 | |
5 | ||
6 | It is available at the usual places: | |

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 2.4 primarily adds support for increasing the number of | |
16 | devices in a RAID5 array, which requires 2.6.17 (or some -rc or -mm | |
17 | prerelease). | |
18 | It also includes a number of minor functionality enhancements and | |
19 | documentation updates. | |
20 | ||
21 | Changelog Entries: | |
22 | - Rewrite 'reshape' support including performing a backup | |
23 | of the critical region for a raid5 growth, and restoring that | |
24 | backup after a crash. | |
25 | - Put a 'canary' at each end of the backup so a corruption | |
26 | can be more easily detected. | |
27 | - Remove useless 'ident' arguement from ->getinfo_super method. | |
28 | - Support --backup-file for backing-up critical section during | |
29 | growth. | |
30 | - Erase old superblocks (of different versions) when creating new | |
31 | array. | |
32 | - Allow --monitor to work with arrays with >28 devices | |
33 | - Report reshape information in --detail | |
34 | - Handle symlinks in /dev better | |
35 | - Fix mess in --detail output which a device is missing. | |
36 | - Manpage tidyup | |
37 | - Support 'bitmap=' in mdadm.conf for auto-assembling arrays with | |
38 | write-intent bitmaps in separate files. | |
39 | - Updates to md.4 man page including section on RESTRIPING and SYSFS | |
