[EMAIL PROTECTED], dear friends and sorry for my English.
This is a poor story about my RAID software onto Debian Sarge (Kernel
2.6.8-2-386). Few days ago I founded on /dev/tty12 this message:
end-request: I/O error dev sda sector 2923593
ATA abnormal status 0x00 on port 0xAC07
Machine was freeze, login from local or remote (ssh) disabled. I had
reboot machine (from reset button) and it blocked at this message:
Starting mdam monitor
but I have access to filesystem (RW) from remote login (ssh), and I have
copy all /var/log directory.
kernel.log said:

On boot machine send me email message:
This is an automatically generated mail message from mdadm
running on backup
A DegradedArray event had been detected on md device /dev/md0.
Faithfully yours, etc.
My machine have 4 disk SATA, and filesystem is composed by 2 RAID sf.
/dev/md0 is a RAID1 (sda1,sdb1,sdc3,sdd4)
/dev/md1 is a RAID5 (sda3,sdb3,sdc3,sdd3)
swap is normal swap (sda2,sdb2,sdc2,sdd2)
You can view fstab and most important logs into /var/log at this
address:
http://www.openclose.it/var/raidfailed/
I don't know there is/are disk/s where problem is located, and I don't
know how I can repaire it. I don't know, again, if problem are HD, swap,
or other hardware parts.
