Recover from dead hard drive in RAID 1 array CentOS 5
Posted on 2009-05-19
I have a server running CentOS 5 with 2 x 18gb Compaq SCSI hard drives in software RAID 1. One of the hard drives is dead and the machine wont boot properly, during the boot process the file system is checked it gives the following error:
fsck.ext3: Bad magic number in super-block while trying to open /dev/hda1 [FAILED]
*** An error occurred during the file system check.
*** Dropping you to a shell; the system will reboot
*** when you leave the shell.
*** Warning -- SELinux us active
*** Disabling security enforcement for system recovery.
*** Run ' setenforce1 ' to reenable.
Give root password for maintenance
(or type Control-D to continue):
I have two new hard drives which I plan on using with this machine for the system and storage (2 x 500gb Hitachi SATA) currently the 18gb drives are for the system and there is a 500gb seagate IDE for the storage.
How do i recover the data from the working 18gb drive to the new 500gb hitachi drives which will be in raid 1?
