I now have a dedicated ESP on /dev/sda2 (non-RAID) and it boots via |
| 30 |
gummiboot (-> UEFI). |
| 31 |
|
| 32 |
dracut assembles the arrays after configuring this: |
| 33 |
|
| 34 |
# /etc/dracut.conf |
| 35 |
|
| 36 |
add_dracutmodules+="lvm bash mdraid" |
| 37 |
|
| 38 |
hostonly="yes" |
| 39 |
|
| 40 |
mdadmconf="yes" |
| 41 |
|
| 42 |
# the uuids of my two arrays ... |
| 43 |
kernel_cmdline+=" rd.md.uuid=7663e24a:1a64ce0f:49545629:46742031 " |
| 44 |
kernel_cmdline+=" rd.md.uuid=8c266e7a:870c97b7:ff199683:6d8c3edb " |
| 45 |
|
| 46 |
# end |
| 47 |
|
| 48 |
|
| 49 |
(lvm isn't necessary but doesn't hurt) |
| 50 |
|
| 51 |
I now wonder if I could |
| 52 |
|
| 53 |
(a) create a RAID1 over /dev/sd[abcd]2 and format it as vfat ESP |
| 54 |
|
| 55 |
or |
| 56 |
|
| 57 |
(b) "clone" /dev/sda2 -> format each /dev/sd[abcd]2 as vfat, copy the |
| 58 |
content of /boot in there and install gummiboot to each harddisk |
| 59 |
|
| 60 |
? |
