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.
15
Release 2.2 fixes a few small bugs and add as few small elements of
16
functionality. Possibly the most interesting is the addition of
17
'README.initramfs' and 'mkinitramfs'. Feedback on these would be
22
- Support write-intent-bitmaps on raid10
23
- Support little-endian (Rather than hostendian) bitmaps.
24
- Return correct error code from 'mdadm -S'
25
- Remove extra blank line from 'mdadm -Eb' output.
26
- Improve option parsing so that -a and -b do not have
27
optional arguements: the arg is either required or not
29
- Allow scanning of devices listed in /proc/partitions even
30
if they don't appear in /dev.
31
- Support --assume-clean in --create mode as well as --build
32
- Add support for --monitor to report to syslog: -y or --syslog.

Thanks to Ross Vandegrift
34
- --monitor now reports which device failed in a 'Fail' message
36
- Improve chance of array starting properly after a crash.
37
mdadm was insisting the event numbers were identical, but this
38
isn't needed, and is a problem if the crash was while the metadata
40
- Support --update==uuid
41
- Added README.initramfs and mkinitramfs to help people use an
42
initram for starting md arrays at boot.
