Hello: This occurs in openSUSE 12.2. I have several raid 1 devices most of them are 1.0 style. During boots the arrays are arbitrarily assembled. For example after first boot some of the arrays are assembled with one drive only. Even if I don't use/mount the devices and reboot the computer they are assembled differently after the new boot. It seems arbitrary which devices are assembled correctly and which not. It is arbitrary too which one of the mirror devices (/dev/sdbx or /dev/sdcx) become part of the array and which not. See the example: First boot: Personalities : [raid1] md1 : active (auto-read-only) raid1 sdb1[2] 20971520 blocks super 1.0 [2/1] [U_] md14 : active raid1 sdc14[2] sdb14[3] 62918468 blocks super 1.0 [2/2] [UU] md16 : active raid1 sdc16[2] sdb16[3] 62918468 blocks super 1.0 [2/2] [UU] md18 : active (auto-read-only) raid1 sdb18[0] 31455104 blocks super 1.0 [2/1] [U_] md8 : active raid1 sdc8[1] sdb8[0] 31438720 blocks super 1.2 [2/2] [UU] md9 : active raid1 sdc9[2] 62918468 blocks super 1.0 [2/1] [_U] md15 : active raid1 sdc15[2] sdb15[0] 62918468 blocks super 1.0 [2/2] [UU] md12 : active (auto-read-only) raid1 sdb12[0] 62918468 blocks super 1.0 [2/1] [U_] md11 : active (auto-read-only) raid1 sdb11[3] 62918468 blocks super 1.0 [2/1] [U_] md13 : active (auto-read-only) raid1 sdb13[3] 62918468 blocks super 1.0 [2/1] [U_] md10 : active raid1 sdb10[3] 62918468 blocks super 1.0 [2/1] [U_] md20 : active (auto-read-only) raid1 sdb20[0] 62918468 blocks super 1.0 [2/1] [U_] md22 : active (auto-read-only) raid1 sdb22[0] 55439552 blocks super 1.2 [2/1] [U_] md7 : active raid1 sdc7[3] 31455164 blocks super 1.0 [2/1] [_U] md6 : active raid1 sdb6[2] 20971520 blocks super 1.0 [2/1] [_U] md19 : active (auto-read-only) raid1 sdb19[0] 62918468 blocks super 1.0 [2/1] [U_] md17 : active (auto-read-only) raid1 sdb17[0] 62918468 blocks super 1.0 [2/1] [U_] md21 : active raid1 sdc21[2] sdb21[3] 48829464 blocks super 1.0 [2/2] [UU] unused devices: <none> You can see that in some /dev/mdx /dev/sdbx devices become part of the array, while in others /dev/sdbx devices become part of the array.

And it goes like this from boot to boot. Why is this? How to fix this? Is this hardware of software issue?
