There is a server running on soft raid-1 with Debian Squeeze, during the update of the server packages received such errors:
- W: mdadm: /etc/mdadm/mdadm.conf defines no arrays.
- /usr/sbin/grub-probe: error: no such disk.
Detailed response from the system:
...

There are 2 errors that need to be corrected:
1. W: mdadm: /etc/mdadm/mdadm.conf defines no arrays.
2. /usr/sbin/grub-probe: error: no such disk.
Fix the first error: W: mdadm: /etc/mdadm/mdadm.conf defines no arrays.
Checking the file contents. /etc/mdadm/mdadm.conf, there must be specified the connected sections by the command:
cat /etc/mdadm/mdadm.conf
System response:
DEVICES /dev/[hs]d*
We see that there are no partitions in the configuration file, we check the contents of the connected partitions in general. mdadm team:
mdadm --detail --scan
System response:
ARRAY /dev/md/0 metadata=1.2 name=rescue:0 UUID=5d83f792:5e36f824:fcb2bb6c:28e7807b ARRAY /dev/md/1 metadata=1.2 name=rescue:1 UUID=bfd9dd1d:7b471ce1:527fb81d:d4ea0227
We present the contents of the file. /etc/mdadm/mdadm.conf This is the view.
vi /etc/mdadm/mdadm.conf DEVICE partitions CREATE owner=root group=disk mode=0660 auto=yes HOMEHOST <system> MAILADDR root # definitions of existing MD arrays ARRAY /dev/md/0 metadata=1.2 UUID=5d83f792:5e36f824:fcb2bb6c:28e7807b ARRAY /dev/md/1 metadata=1.2 UUID=bfd9dd1d:7b471ce1:527fb81d:d4ea0227
Correcting the second mistake: /usr/sbin/grub-probe: error: no such disk.
Checking the file contents. /boot/grub/device.map For the presence of sections by the team:
cat /boot/grub/device.map
System response:
(hd0) /dev/disk/by-id/scsi-35000c5004a3e9a73 (hd1) /dev/disk/by-id/scsi-35000c5004a3f96a1
Now we need to make sure that what is written in the file corresponds to reality, to do this, execute a command and compare the system’s response with what is in the file. /boot/grub/device.map After completing the command:
ll /dev/disk/by-id | grep scsi-
System response:
lrwxrwxrwx 1 root root 9 Ноя 30 18:56 scsi-SATA_ST3000DM001-9YN_S1F07VNV -> ../../sda lrwxrwxrwx 1 root root 10 Ноя 30 18:56 scsi-SATA_ST3000DM001-9YN_S1F07VNV-part1 -> ../../sda1 lrwxrwxrwx 1 root root 10 Ноя 30 18:56 scsi-SATA_ST3000DM001-9YN_S1F07VNV-part2 -> ../../sda2 lrwxrwxrwx 1 root root 10 Ноя 30 18:56 scsi-SATA_ST3000DM001-9YN_S1F07VNV-part3 -> ../../sda3 lrwxrwxrwx 1 root root 9 Ноя 30 18:56 scsi-SATA_ST3000DM001-9YN_S1F08J4D -> ../../sdb lrwxrwxrwx 1 root root 10 Ноя 30 18:56 scsi-SATA_ST3000DM001-9YN_S1F08J4D-part1 -> ../../sdb1 lrwxrwxrwx 1 root root 10 Ноя 30 18:56 scsi-SATA_ST3000DM001-9YN_S1F08J4D-part2 -> ../../sdb2 lrwxrwxrwx 1 root root 10 Ноя 30 18:56 scsi-SATA_ST3000DM001-9YN_S1F08J4D-part3 -> ../../sdb3
Naturally, scsi-35000c5004a3e9a73 fails scsi-SATA_ST3000DM001-9YN_S1F07VNVeh scsi-35000c5004a3f96a1 fallow scsi-SATA_ST3000DM001-9YN_S1F08J4D
Fix the file. /boot/grub/device.map:
vi /boot/grub/device.map
was:
(hd0) /dev/disk/by-id/scsi-35000c5004a3e9a73 (hd1) /dev/disk/by-id/scsi-35000c5004a3f96a1
became:
(hd0) /dev/disk/by-id/scsi-SATA_ST3000DM001-9YN_S1F07VNV (hd1) /dev/disk/by-id/scsi-SATA_ST3000DM001-9YN_S1F08J4D
Save the modified file and update the downloader grub team:
update-grub
And after updating the grub, we finish updating the system with the command:
aptitude safe-upgrade

After updating the kernel, we overload our server with a command:
reboot
Errors corrected:
- W: mdadm: /etc/mdadm/mdadm.conf defines no arrays.
- /usr/sbin/grub-probe: error: no such disk.
Task completed, errors fixed, server updated.
I was with you. Sergey Lazarenko.
