Default NPF UEFI boot on USB

Hi,

Have mostly run vanilla NetBSD in the past, on hard drives, bios, etc. Not really very experienced with NetBSD in general, however.

Have a usb UEFI boot stick that wants to dump me to the command line with rootfs in read-only mode, no matter how I select the boot option (1,2, or 3). I can then remount the root filesystem in read-write mode with the command "mount -uw /", exit from the shell, and soon the normal login appears, and all is fine ... except for the npf and anything else in rc.conf that wants to write. The OS runs OK otherwise even with the late r/w status change.

Message log shows /dev/sd1 and /dev/dk1 devices. I end up with /dev/dk1 as the root file system. (Why not dk1a - maybe partition issue?) Note I have /dev/dk1 in fstab as read-write. Any suggestions?

NPF seems very intuitive and am looking forward to using it once I can get the early read-only mode problem ironed out. I should note that this is IIRC a memory stick image downloaded from NetBSD.org, so it shouldn't have a partition issue or I wouldn't think so anyway ...

I think rons is referring to npf(7).

Perhaps post the log (or link to it if it is large) and also the content of /etc/fstab and the output of mount(8).

Not sure if I'll be able to help directly though because I don't use NetBSD (sorry).

Thanks for the reply. Here's some pertinent snips from syslog:
Code:
sd1: fabricating a geometry
sd1: 15193 MB, 15193 cyl, 64 heads ...
sd1: fabricating a geometry
sd1:GPT GUID 29A73 ...
dk0 at sd1: "EFI system" ...
dk1 at sd1: "NetBSD"
boot device: sd1
root on: dk1
root filesystem type: ffs
/dev/dk1: file system not clean; please run fsck ...
sd1: fabricating a geometry ...
sd1: 15193 MB, 15193 cyl, 64 heads ...
sd1: GPT GUID: 299A73 ...
dk0 at sd1: "EFI system"
dk1 at sd1: "NetBSD"
boot device: sd1
root on dk1
root filesystem type: ffs
/dev/dk1: file system not clean; please run fsck
For some reason, the sequence leading to fsck is repeated twice. I notice that when I exit the shell there is a quick message about root filesystem being mounted twice.

I have tried fsck (which works) - but the next boot it does the same thing anyway. I put fsck into /etc/rc.d/root but that is too late in the boot process, and doesn't allow npf to write, and thus it does not load. So, what do you think?

Here is fstab:
Code:
# NetBSD /etc/fstab
# See /usr/share/examples/fstab/ for more examples.
/dev/dk1        /       ffs     rw              1 1
kernfs          /kern   kernfs  rw
ptyfs           /dev/pts        ptyfs   rw
procfs          /proc   procfs  rw
tmpfs           /var/shm        tmpfs   rw,-m1777,-sram%25

Maybe the output of disklabel sd1 could help to see the partitioning and explain the weirdness of dk1 etc.

Hi Onauk,

Well , disklabel does give a confusing result. First, output of listwedges:

Code:
dkctl sd1 listwedges

/dev/rsd1: 2 wedges found:
   dk0: EFI system, 262144 blocks at 4096, type:msdos
   dk1: NetBSD, 25165824 blocks at 266240, type ffs

dkctl dk1 getwedgeinfo

   dk1: at sd1: NetBSD
   dk1: 25165824 blocks at 266240, type ffs

So, listwedges seems OK. But, weirdness in disklabel:

Code:
disklabel sd1

/dev/rsd1:
type:SCSI
disk: USB3.0 CRW -SD
label: fictitious
flags: removable
bytes/sector:  512
sectors/track: 32
tracks/cyl: 64
total sectors: 31116288

4 partitions:
   size  offset fstype  fsize   bsize   
a: 31116288  0  4.2BSD  0  0
b: 31116288  0  unused  0  0
disklabel: boot block size 0
disklabel: super block size 0
The info in the partitions list is not logical and seems to be something that wouldn't even be allowed by the partitioner ...

Perhaps the gpt output will give a better picture of the disk than disklabel by itself:

gpt show sd0

Code:
start   length   index  description
0           1           PMBR
1           1           Pri GPT header
2           32          Pri GPT table
34          4062        Unused
4096      262144    1   GPT part - EFI System
266240   25165824   2   GPT part - NetBSD FFSv1/FFSv2
23432064  5684191       Unused
31116235   32            Sec GPT table
31116287   1              Sec GPT header
So, this does not look unusual, does it?

I do not look at GPT very often. What is the purpose of the second table/header? Now that I've been thinking about this stick, I remember that I downloaded the installation memory stick image from NetBSD, and then myself did the installation to this stick (that I'm using now :-) ).

So, any booboo is probably mine. Any ideas?

BTW, here is uname -a :

NetBSD 9.0 (GENERIC) #0: Fri Feb 14 00:06:28 UTC 2020 mkrepro@mkrepro.NetBSD.org:/usr/src/sys/arch/amd64/compile/GENERIC amd64

Edit: Perhaps it was the bleeding edge image for NetBSD 9.0, and I should just upgrade to a newer stick image. But then - ugh - I have to reinstall all the apps I've put onto the stick, like this newish version of Firefox that I'm using, etc. Would rather get this one perfected, in the interest of being lazy.

From https://daemonforums.org/showpost.ph...51&postcount=3 we have:

Quote:
Note that, unlike OpenBSD, NetBSD does not write a BSD label to the secondary GPT header, meaning there won't be any a-z slices for wd*, sd* and ld* disks (i.e., no ld0a, ld0b...), but just dk* logical disk wedges (dk1, dk2, dkn...), since the filesystem won't be structured as a single BSD label (partition) containing various slices, but as a set of standard independent partitions (similarly to Linux or Windows). I think this is meant to allow for better compatibility with other OSs. See dk(4).
This answers two questions, being "What is the purpose of the secondary header/table?", and "Why are there not any alphanumeric slices, like dk1a?"

I'm wondering if the presence of the secondary info is confusing the boot process? Just throwing things out there. Pays to read the other guys posts who came before LOL. Sorry I am monopolizing this thread, but I am getting my thoughts organized by blathering LOL.

Sure hope I can get the firewall (npf) working on this stick, as everything else in this setup is pretty nifty. I can get a *very* recent version of firefox going, wherein on some of the other OS's to do that you compile it yourself.
