Hi,

I would like to request an assistant.

I have new pair additional drives (With ready Data) and i wish to mirror both of the drive .

May i know whether the following command is safe without losing my data ?

mdadm --create /dev/md4 --metadata=0.90 --level=1 --raid-devices=2 missing /dev/sdd1

For your information i have other running raid device on the server and i would like to add the new /dev/md4 .

Appreciates experts comment whether the above command will works without losing the data inside /dev/sdd1 .

Thank you
