HOWTO

# mdadm 2.5.3
# ===========
# Slackware 10.0's 'mdadm' package includes version 1.6.0, 10.1's includes
# 1.8.0, and 10.2's includes 2.1

# If you have trouble getting it from the URL below, you can get it from
# here instead (but not as a .tar.bz2 and without a pgp sig)

cd
test -f installed/mdadm-2.5.3.tar.bz2 && mv installed/mdadm-2.5.3.tar.bz2 .

# Verify tarball w/ md5sum:
# (this came from my gpg-verified tarball)
echo "9ca780fbb2002e935ba5f7a21e50ab66  mdadm-2.5.3.tar.bz2" | md5sum -c

# Verify tarball w/ sha1sum:
# (this also came from my gpg-verified tarball)

# follow these instructions instead of running 'make install'

# If you did not create a package...

# Install the example config file as /etc/mdadm.conf
# If you already have a config file and it's different than the example one,

cp mdadm.conf-example /etc/mdadm.conf

## If you want to run mdadm in monitor mode, e-mailing root@foo.org (from
## root@foo.org), add something like this to your /etc/mdadm.conf:
# ARRAY /dev/md0 devices=/dev/hda3,/dev/hde3,/dev/hdg3
# MAILFROM root@foo.org
# MAILADDR root@foo.org

# Run mdadm like so (see 'man mdadm' for more options):
# (-F = monitor mode, -y = syslog, -f = daemon, -s = scan config file
# and/or /proc/mdstat, -i = pid file)
/sbin/mdadm -F -y -f -s -i /var/run/mdadm.pid
