i have a problem,i install a new server gentoo zfs for xen,
there was some problems,

i found some one did a custom iso:link below:
https://linux.arantius.com/installing-gentoo-into-a-luks-encrypted-zfs-root
and there is no module efivars inside this package or another:
error:
Code:
modprobe efivarfs
modprobe: ERROR: could not insert 'efivarfs': No such device

83657664 ... the 'minimal' CD (on which that CD is based) doesn't support EFI booting.

This looks like a the iso is corrupt, or incomplete. What sort is boot disk is this, CD, or USB? ... and if the latter how was it created?

best ... khay

i finger something out.
it is a famous raid card:lsi mptsas 1068e
shit
it is cheap,but bad card
it is slow,i flash to it mode,
can not see any disks from this card,because it's chip
can not boot any disks directly from raid card of it mode,must from something else.
if i flash to ir mode, it's so slow.
anyway,i found something else!
thanks
