               *** Announcement: dmraid 1.0.0-rc2 ***

Following a good tradition, dmraid 1.0.0-rc2 is available at
http://people.redhat.com:/~heinzm/sw/dmraid/ in source and i386 rpm,
before I leave for a 2 weeks vacation trip followed by LWE ;)

Won't read my email before July, 30th.

dmraid (Device-Mapper Raid tool) discovers, [de]activates and displays
properties of software RAID sets (ie. ATARAID) and contained DOS
partitions using the device-mapper runtime of the 2.6 kernel.

The following ATARAID types are supported on Linux 2.6:

Highpoint HPT37X
Highpoint HPT45X
Intel Software RAID
Promise FastTrack
Silicon Image Medley

This ATARAID type can be discovered only in this version:
LSI Logic MegaRAID

Please provide insight to support those metadata formats completely.


See files README and CHANGELOG, which come with the source tarball for
prerequisites to run this software, further instructions on installing
and using dmraid!

CHANGELOG is contained below for your convenience as well.

Call for testers:

I need testers with the above ATARAID types, to check that the mapping
created by this tool is correct (see options "-t -ay") and access to the ATARAID
data is proper.

You can activate your ATARAID sets without danger of overwriting
your metadata, because dmraid accesses it read-only unless you use
option -E with -r in order to erase ATARAID metadata (see 'man dmraid')!

This is a release candidate version so you want to have backups of your valuable
data *and* you want to test accessing your data read-only first in order to
make sure that the mapping is correct before you go for read-write access.

The author is reachable at <Mauelshagen at RedHat.com>.
Later, I told you ;)

For test results, mapping information, discussions, questions, patches,
enhancement requests and the like, please subscribe and mail
to <ataraid at redhat.com>.
