It looks like the information was lost on the raid?

Question

System administration

RAID-1 out of two (id1 and id0) on id1, one hard drive has failed and id1 has switched to the degraded state. The system with id0 worked. I inserted a new disk, went into the configurator and ran rebuild. At 3%, I had to press esc and select stop (there was still abort). Now with id0 it does not see the system, I started rebuild again. Please help.

Answer 1

Now with id0 does not see the system

Naturally, there is no RAID.

Please help.

Take out the whole disk (if it is still alive), make a copy from it, restore the system boot.

Yes, not a pleasant thing
Insert livecd copy information from it
Do not try to install mdadm delete everything
