Hi fellow selfhoster,
Im a bit lost on the following scenario and im unable to find any documentation about it so i was hoping some smart people here could point me in the right direction.
I have a linux software raid 6 that contains a LUKS partition with ext4 in it. I would like to automount the ext4 when im rebooting. The root partition is also using LUKS and i have successfully setup the decryption for this parition but im uncertain on how to do this with this raid setup since im not sure where in the boot process linux recognizes my raid and when the decryption happens.
This is what i have:
[root@nfs-rocky-1 ~]# cat /etc/mdadm.conf
ARRAY /dev/md/server1:0 metadata=1.2 UUID=3e198408:2236ed3d:1dc13a8e:e5f91e52
On a reboot the raid does get automaticly recognizes but i still have to do cryptsetup luksOpen /dev/md0 raid & mount /dev/mapper/raid /mnt/data.
What would be the best way to do this? Im a bit scared of doing this im not certain of since i don’t want my machine to be stuck at a boot.
Just a like to an article that dicusses something like this already would help me greatly.
@Hercules I created it on my own, because I have some keys for other devices, too.
But you can place it, where you want.
But with crypttab.d I have a simple connection to crypttab configuration file.
