Date: Sat, 30 Apr 2005 21:59:21 -0500 Message-ID: <42744609.10101@advocap.org> Mime-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Return-path: Sender: linux-raid-owner@vger.kernel.org To: linux-raid@vger.kernel.org List-Id: linux-raid.ids I cloned a system with 2 drives and 2 raid 1 partitions. I took a drive out of the old system. Recreated the raids to get a new uuids. Partitioned a new drive and added the partitions. There were a couple other problems that I'm pretty sure was caused by a bad sata controller but think I have that under control. So here is my problem. Any time I reboot only the partitions on the first drive are active. If I switch drives it's always the first one that is active. Here is my mdadm.conf DEVICE /dev/sd* ARRAY /dev/md0 level=raid1 num-devices=2 UUID=647381d7:fb84da16:f43e8c51:3695f234 ARRAY /dev/md1 level=raid1 num-devices=2 UUID=90b9e6d2:c78b1827:77f469ad:0f8997ed This is all after reboot: cat /proc/mdstat Personalities : [raid1] md0 : active raid1 sda1[1] 586240 blocks [2/1] [_U] md1 : active raid1 sda2[1] 194771968 blocks [2/1] [_U] mdadm -E /dev/sda1 /dev/sda1: Magic : a92b4efc Version : 00.90.00 UUID : 647381d7:fb84da16:f43e8c51:3695f234 Creation Time : Sat Apr 30 06:02:47 2005 Raid Level : raid1 Raid Devices : 2 Total Devices : 1 Preferred Minor : 0 Update Time : Sat Apr 30 21:47:22 2005 State : clean Active Devices : 1 Working Devices : 1 Failed Devices : 0 Spare Devices : 0 Checksum : b8e8e847 - correct Events : 0.4509 Number Major Minor RaidDevice State this 1 8 1 1 active sync /dev/sda1 0 0 0 0 0 removed 1 1 8 1 1 active sync /dev/sda1 mdadm -E /dev/sdb1 /dev/sdb1: Magic : a92b4efc Version : 00.90.00 UUID : 647381d7:fb84da16:f43e8c51:3695f234 Creation Time : Sat Apr 30 06:02:47 2005 Raid Level : raid1 Raid Devices : 2 Total Devices : 2 Preferred Minor : 0 Update Time : Sat Apr 30 21:26:07 2005 State : clean Active Devices : 2 Working Devices : 2 Failed Devices : 0 Spare Devices : 0 Checksum : b8e8e1d8 - correct Events : 0.4303 Number Major Minor RaidDevice State this 0 8 17 0 active sync /dev/sdb1 0 0 8 17 0 active sync /dev/sdb1 1 1 8 1 1 active sync /dev/sda1 After adding /dev/sdb1 to md0: cat /proc/mdstat Personalities : [raid1] md0 : active raid1 sdb1[0] sda1[1] 586240 blocks [2/2] [UU] md1 : active raid1 sda2[1] 194771968 blocks [2/1] [_U] unused devices: mdadm -E /dev/sda1 /dev/sda1: Magic : a92b4efc Version : 00.90.00 UUID : 647381d7:fb84da16:f43e8c51:3695f234 Creation Time : Sat Apr 30 06:02:47 2005 Raid Level : raid1 Raid Devices : 2 Total Devices : 2 Preferred Minor : 0 Update Time : Sat Apr 30 21:51:11 2005 State : clean Active Devices : 2 Working Devices : 2 Failed Devices : 0 Spare Devices : 0 Checksum : b8e8e99a - correct Events : 0.4551 Number Major Minor RaidDevice State this 1 8 1 1 active sync /dev/sda1 0 0 8 17 0 active sync /dev/sdb1 1 1 8 1 1 active sync /dev/sda1 mdadm -E /dev/sdb1 /dev/sdb1: Magic : a92b4efc Version : 00.90.00 UUID : 647381d7:fb84da16:f43e8c51:3695f234 Creation Time : Sat Apr 30 06:02:47 2005 Raid Level : raid1 Raid Devices : 2 Total Devices : 2 Preferred Minor : 0 Update Time : Sat Apr 30 21:51:43 2005 State : clean Active Devices : 2 Working Devices : 2 Failed Devices : 0 Spare Devices : 0 Checksum : b8e8e9d0 - correct Events : 0.4555 Number Major Minor RaidDevice State this 0 8 17 0 active sync /dev/sdb1 0 0 8 17 0 active sync /dev/sdb1 1 1 8 1 1 active sync /dev/sda1 Any Idea what is wrong?
