Use metadata version 1.2 instead of 0.9.
Thanks, I'll try that. I'm use to metadata 0.9, because GRUB have (had?) some issue with the newer ones.
If that doesn't work, and you need to use metadata 0.9, then check /etc/default/grub and make sure that GRUB_CMDLINE_LINUX contains "rd.md.uuid=<THE UUID OF YOUR md0>".
T.H.A.N.K Y.O.U. :) I was sure I had to pass uuid of the partition, not md0. It is working now. One last thing: since Linux Rescue CD does not recognize selinux, / mounted itself as read-only. Disabling SeLinux helped. I think I need to relabel all the files on a new host. So generally: - edit /etc/default/grub and grub2-mkconfig, - generate mdadm.conf (I think a copy of it resides inside initramfs), - fstab (root mounts anyway, so just for swap patition), - disable selinux, - generate initramfs with dracut.
Big thanks to all of you. It was rough, but it's done.
