Subject: raid 0+1 and 1+0 with mdadm
Date: Thu, 30 Sep 2004 10:56:03 -0700 [thread overview]
Message-ID: <1096566962.3539.15.camel@rich> (raw)
my 0+1 and 1+0 raid devices are not getting started on system boot. i
realize this could be fixed through the sysinit scripts but mdadm -As
should be able to handle this.
here is my mdadm.conf
DEVICE /dev/hdb1 /dev/hdb2 /dev/hdb3 /dev/hda5 /dev/hda6 /dev/hda7
/dev/hdb5 /dev/hdb6 /dev/hdb7 /dev/hda8 /dev/hda9 /dev/hda10 /dev/md3
/dev/md4 /dev/md6 /dev/md7
ARRAY /dev/md3 level=0 num-devices=3
devices=/dev/hdb1,/dev/hdb2,/dev/hdb3
ARRAY /dev/md4 level=0 num-devices=3
devices=/dev/hda5,/dev/hda6,/dev/hda7
ARRAY /dev/md6 level=1 num-devices=2
devices=/dev/hdb5,/dev/hdb6,/dev/hdb7
ARRAY /dev/md7 level=1 num-devices=2
devices=/dev/hda8,/dev/hda9,/dev/hda10
ARRAY /dev/md5 level=1 num-devices=2 devices=/dev/md3,/dev/md4
ARRAY /dev/md8 level=0 num-devices=2 devices=/dev/md6,/dev/md7
as you can see /dev/md5 is built on /dev/md3 and /dev/md4 and /dev/md8
is built on /dev/md6 and md7.
when I run "mdadm -As" i get the following output:
mdadm: /dev/md3 has been started with 3 drives.
mdadm: /dev/md4 has been started with 3 drives.
mdadm: /dev/md6 has been started with 2 drives and 1 spare.
mdadm: /dev/md7 has been started with 2 drives and 1 spare.
mdadm: no devices found for /dev/md5
mdadm: no devices found for /dev/md8
if i then immediately run "mdadm -As" again it starts /dev/md5 and
/dev/md8.
why do i have to run it twice and why does it not start all devices the
first time?
