Infrastructure Software

I installed RHE AS E 3, the server has 2 HD' s and I configured him in RAID 1 using the following partitions:

#cat /proc/partitions

major minor name size

9 0 md0 100 MB
9 1 md1 15 GB
9 2 md2 2 GB
9 3 md3 52.9 GB
8 0 sda 70 GB
8 1 sda1 100 MB
8 2 sda2 15 GB
8 3 sda3 2 GB
8 4 sda4 1 (partition extended)
8 5 sda5 52.9 GB
8 16 sdb 70 GB
8 17 sdb1 100 MB
8 18 sdb2 15 GB
8 19 sdb3 2 GB
8 20 sdb4 1 (partition extended)
8 21 sdb5 52.9 GB

and the RAID remained thus:

#df

Filesystem Mounted on
/dev/md1 /
/dev/md3 /Datos
/dev/md0 /boot

#cat /proc/swaps
/dev/md2




I had to test the correct operation of the RAID, asi that I removed physically the hard disk of the server, at the moment that copied some data files. The RAID functioned correctly, then I did:

raidhotremove /dev/md0 /dev/sda1
raidhotremove /dev/md1 /dev/sda2
raidhotremove /dev/md2 /dev/sda3
raidhotremove /dev/md3 /dev/sda5

Subsequently I resumed and I introduced the hard disk. Later I did the following thing:

mdadm /dev/md0 -a /dev/sda1
mdadm /dev/md1 -a /dev/sda2
mdadm /dev/md2 -a /dev/sda3
mdadm /dev/md3 -a /dev/sda5

Once the hard disks were synchronized, I resumed and the following legend appears:

GRUB Loader stage2
>


But when predicament any key appears me a new one line:

GRUB Loader stage2
>

How can I correct this?, someone can help me?
