Hi.
My md0 is broken because of a damaged sda.
It was simple to find out which on it is thanks to lsdrv by Mr Turmel.
Now I have a new disk, same size, as sda with sda1 partition - same size -
formatted as Linux raid autodetect.
In the end I like to end up with the new sda1 as member of md0 and I need to put
my boot information there, since sdb1, also member of md0, seems to no have no
such info because the system wasn't booting with a missing sda1.
I am afraid of loosing data, so I prefer asking, what to do next.
Please guide, I have the system up and running on a sysrescd live distro.
Thank you very much.
