https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D258987 Bug ID: 258987 Summary: 13.0-RELEASE installer broken redundancy with UEFI and ZFS Product: Base System Version: 13.0-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Many People Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: freebsdbugzilla@agneau.org When installing FreeBSD 13.0-RELEASE with UEFI and multi-disk (mirror or ra= idz) ZFS , the expected redundancy is broken twice. 1/ An EFI partition is created on all disks of the pool BUT only the EFI parti= tion of the first disk of the pool is formated and setup, the EFI partition of t= he other disks are not formated (and of course not setup). As a result, if the first disk of the pool fails, the server will not be ab= le to reboot because of missing content of the EFI partition on the remaining disks. 2/ The installer add an entry in the fstab to mount permanently the efi partit= ion of the first disk to /boot/efi . If that physical disk fails, you have one mounted filesystem from a failed disk. This may jeopardize the stability of the system. One should never mou= nt permanently a filesystem from a non-raid device on a server build for redundancy. All of this is new to 13.0-RELEASE and seems added by the following commit= =20 https://cgit.freebsd.org/src/commit/?id=3D0b7472b3d8d2f1e90fade5236b44fd98d= 8e396c2 Previous releases (12.1, 12.2) setup correctly the EFI partition of ALL dis= ks and don't add /boot/efi to any physical disk in the fstab. I understand, the new (13.0) method for populating the EFI partition requir= e it to be mounted at install time. The installer should loop thru each EFI partition to format it , mount it temporary, set it up, and unmount it. This could also be done by freebsd-update when needed. By doing this, we could get EFI/zfs installation redundancy reliable again. --=20 You are receiving this mail because: You are the assignee for the bug.=
