Imaging a Linux box that has 2 RAID Arrays
Hi guys,
Any help appreciated.
I have a linux box with 2 RAID arrays set up.
Disk 1+2: RAID 0
Disk 3-6: RAID 5
Guys,
I want to be able to do this:
1)Make an image of my Linux O/S eg.ghost?
2)How do I do this with a RAID setup?
3)What would be the procedure for not only creating the image, but the restore process?
Thanks in advance.
Simon

A1. So you are using RAID1, not RAID 0. Yes. Just need a spare same model disk to replace the bad one (the LED
indicator will tell you which one is bad).
A2. RAID1 give you high availability, which your server is still running while one of disk fail.
Backup or image covers you DRP (Diaster Recovery Plan), in case the side down and you have the image/backup
to restore on other site in order for business continuity.
A3. Yes.
A4. Boot floppy for the situation that your disk image doesn't boot.
Ghost tool gives you faster image procedure and clone to different size of disk or to a disk image file.
It is separate floppy which you need to buy the software license.
Ghost is not the floppy from step 1.

Gosh youre a legend!
Can I just clarify something mate please.......
Basically Im pretty new to this.
Ive been asked to come up with a solution for us if our server goes down.
Im confused about this because I cannot see in what situation you need to make an image of the RAID 1 disk because if 1 disk fails, then we still have availability through the other RAID 1 disk.
Q.Is this correct that the server wont go down if one RAID 1 disk fails?
Q.Do you guys or is it good practice to image the system disk eg.the RAID 1 disk for disaster recovery? Even though you still have availability if one disk fails? Whats the point in imaging a RAID 1 disk?
- The RAID 1 disks are each 140GB
- The 'linux' version we are using is VMWare ESX Server 2.5
Q.If a RAID 1 disk goes down, should we still be able to function until we get the faulty disk replaced?
Q.With the 3 steps you outline above,
Is step 1 basically if you cannot boot?
With step 2, are you first booting from a floppy that contains the ghost program? Is this the floppy that was created in step 1?
Thanks so much for your help wes.
