I have on a UCS 4.3-3 Server a software-RAID (mdadm). I want to remove that. I have a third 2TB Harddisk (same type and same vendor). I have read, that i must clone the data. But can some tell me, which tools i can use (Clonezilla) and which settings is needed that i can remove the RAID-Informations from the current system
Reason: The Software for Databackup cannot restore to RAID-Systems. I tried yesterday and it was a fail.
What I do: I run Clonezilla to make a image of one of the RAID-HDDs. Then I repair the GRUB with SuperGrub2. Then the System is starting normaly. But mdadm is running (cat /proc/mdstat)
Hi,
well, if you are really sure your system does not use the md array any more you should be fine to remove the mdadm tool by:
apt remove mdadm
If everything works after a reboot as expected
apt purge mdadm
And check again.

After using the commands i have following screen
Loading, please wait
Busybox v1.22 (Debian 1:1.22.0- ....
Enter 'help' for a list of built.in commands
(initramfs) _
and the system hangs.
When i try to repair it with Grub2 then the same result
Well,
“initramfs: GRUB 2 began the boot process but there was a problem passing control to the operating system. Possible causes include an incorrect UUID or root= designation in the ‘linux’ line or a corrupted kernel.” (from here)
Looks like your system still used the md device. Therefore I wrote “if you are really sure…”. Now you have a mess.
Boot through DVD into rescue mode and update the GRUB configuration to match the UUID (use blkid) of your current root device. If unsure how to do re-install mdadm and hope your system boots up again.
