Hello,

I've posted a couple of days ago about a problem i have on my raid1
array. I used a Fedora Core 2 system to create a raid array using mkraid
at the time, and created /dev/md0 and /dev/md1. While /dev/md1 has been
nice to me, /dev/md0 keeps loosing a disk from the array and i don't
know why.

It is sitting on a silicon image (sil3112) raid card with two maxtor
s-ata 160GB drives. Here is the output of mdstat and mdadm -D /dev/md0

Personalities : [linear] [raid0] [raid1]
md1 : active raid1 sdb3[1]
      19542976 blocks [2/1] [_U]

md0 : active raid1 sdb2[1]
      97667072 blocks [2/1] [_U]

unused devices: <none>

/dev/md0:
        Version : 00.90.01
  Creation Time : Tue Jun  8 18:20:49 2004
     Raid Level : raid1
     Array Size : 97667072 (93.14 GiB 100.01 GB)

I've kept on reattaching /dev/sda2 to /dev/md0, it then works for a
couple of days, freezes again and detaches itself. Has anyone
experienced this or could tell me how i could investigate this ? I'm
running a 2.6.7 kernel.

Thanks in advance,
Steph
