yes I know sir.My long term goal is Security side.So I am just getting information about that field thats it

@DashrenderWhen I reboot with two hard disk(sda,sdb) there is no issue.When I connect a new hard dis(sdc) after removing sdb I check the hard disk separately the ssue came as kernel panic

@Dashrender Its Sofware RAID1

@scottalanmiller Ok I understood.I went to Manager said that it cannot be done and the RAID configured device will lost the data and this is impossible.But he ask the explanation behind this and said to explain briefly

@scottalanmiller I used to update Linked in Profile

@scottalanmiller
Sir Please refer this image one person said me that RAID 1 member can be boooted by installing bootloader.Whether it is possible Sir.I don't know about that one small doubt came after this image seen

@scottalanmiller said:

you can't do it this way.

Ok Sir.I will explain this to my Manager and after that I acknowledge you sir

@thecreativeone91 Whether that method is not possible with the one hard disk Sir.You said that the data loss may be occured but I tried the process by booting sda hard disk alone in rescue mode and seen the data with out any loss in the shell mode.

@scottalanmiller Ok Sir.But my manager said that he needs to see the data to be present in the individual hard disk so only trying to see the data in individual disk.Why this cannot be done.Can you please say

@scottalanmiller There are two hard disk(sda,sdb) with RAID 1 where one of the hard disk (sdb) is made as failure and that was removed successfully.Then new hard disk(sdc) is added after removing the sdb and after that sdc is added successfully and now sda,sdc are present with RAID 1 which was resynched the data properly.When I connect only sdc to check whether the data is present in sdc alone the hard disk does not boot into Centos.When I connect two hard disk sda,sdc means the OS is booting without any issue.And I tried to boot with sda alone but the sda alone is not booted properly.The system is not production system.The system is being tested and this testing method to be implemented in Client to save data from the File Server

@scottalanmiller
My Client is using the Centos 6.2 and I am configuring the RAID 1 in Centos 6.2.I have confirmed the RAID 1 by the cat /proc/mdstat.Then I booted the system with the two hard disk at the same time and then I booted the hard disk which was synched the data was alone booted by disconnecting the other hard disk from the system from the motherboard.Then the system was booted to see the data in Centos but it was booting without the other hard disk

Hi All,
Good Morning.I have configured the RAID1 in centos 6.2 by 2*250 GB hard disk. I checked my RAID1 by booting the system in single hard disk but the hard disk does not booted and also made one hard disk as failed and added new hard disk and synched the data from one hard disk and also checked the synched hard disk which was not booting in single hard disk.I have installed the grub in two hard disk and tried the same issue coming.The error I saw was "Kernal Panic Error". Can anyone help me to solve this issue.
