I am trying to migrate from a single disk drive system to a double disk drive software raid-1 system that already has a running system on it. Meaning that formatting and having a new installation of ubuntu using raid-1 is NOT an option.
In this process I have to copy the contents from main disk (/dev/sda1) to mounted raid array (/dev/md0).
First Attempt to Copy:
sudo cp -dpRx / /mnt/md1
Second Attempt to Copy:
sudo rsync -avxHAXS --delete --progress / /mnt/md1
Both of them end with warnings. Not sure if they end successfully.
Which command should I use (from the two above or something else like dd
) and with which parameters in order to have the md1 raid-array prepared for next reboot?
EDIT:
This is the warning message I got from "cp" command on my first attempt:
cp: cannot stat `/home/george/.gvfs': Permission denied
This is the error message I got from "rsync" command on my second attempt:
rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1070) [sender=3.0.9]
