It's unorthodox but it's a replacement of zeroing the superblock with mdadm before adding the partition back to into the array. >> Once that is successful - i run mdadm --manage /dev/md0 --add /dev/sdd1 >> >> And the sync process starts, and when it is done yesterday, I ran this >> and got these errors: >> >> root@rider:~# grub-install --recheck --no-floppy /dev/sdc >> error: superfluous RAID member (2 found). >> error: superfluous RAID member (2 found). >> error: superfluous RAID member (2 found). >> error: superfluous RAID member (2 found). >> error: superfluous RAID member (2 found). >> Installation finished.

No error reported. There are a few bugs on b.d.o that correspond to this error but none that fit your case, AFAICT. "grub-install" does say "Installation finished. No error reported." You could check whether grub's OK via bootinfoscript (although the only real test'll be a reboot...). http://sourceforge.net/projects/bootinfoscript/ >> My parted -l is: >> >> Disk /dev/sda: 1000GB >> Number Start End Size Type File system Flags >> 1 32.3kB 1000GB 1000GB primary ext3 raid >> >> Disk /dev/sdb: 1000GB >> Number Start End Size Type File system Flags >> 1 32.3kB 1000GB 1000GB primary ext3 raid >> >> Disk /dev/sdc: 1000GB >> Number Start End Size Type File system Flags >> 1 1049kB 996GB 996GB primary ext3 raid >> 2 996GB 1000GB 4204MB primary linux-swap(v1) >> >> Disk /dev/sdd: 1000GB >> Number Start End Size Type File system Flags >> 1 1049kB 996GB 996GB primary ext4 raid >> 2 996GB 1000GB 4204MB primary linux-swap(v1) > > Why do you have file-systems on your partitions ?
