Create a new RAID 1 with existing hard drive without losing data
Hi All,
We have two internal disks in BL 460C G10 blade (in C7000) and on one of them the OS is installed and rest of the app data is also stored. The another disk is not in use.
Now, we want to create a RAID 1 from these disks. Is it possible to do this without losing data?

Re: Create a new RAID 1 with existing hard drive without losing data
If the dis currently is a RAID0 you can extend to RAID1, if it is a plain disk you need to backup and restore.
Hope this helps!
Regards
Torsten.

Re: Create a new RAID 1 with existing hard drive without losing data
Hi Torsten,
No, we haven't configured any raid, its just a separate disk.
Is there any way we could put these disk (one used + one used) in RAID1 and mirror the used disks data onto another disk.

Re: Create a new RAID 1 with existing hard drive without losing data
I think it should be possible to create a RAID0 on the other drive, copy your data and finally extend the RAID0 to RAID1.
Hope this helps!
Regards
Torsten.

Re: Create a new RAID 1 with existing hard drive without losing data
Hi Torsten,
How to copy data? Are you talking about rsync?

Re: Create a new RAID 1 with existing hard drive without losing data
If currently the disk is not in a RAID array, there really isn't a simple path to get to where you want to be without destroying the data on the disk.

Re: Create a new RAID 1 with existing hard drive without losing data
Hi Torsten,
If i use dd to clone the used hard disk with the another unsed one (which i add to RAID0), will it work?
Will the cloning of hard drive from dd in rhel7 will do tht work?
