Asus E45M1-M PRO no longer booting since BIOS update

2021-02-08 Thread Alastair Hogge
Hello,

Recently I wanted to resurrect and old AMD Bobcat (14h) for use with
kgdb over dconschat. The system booted a
FreeBSD-13.0-ALPHA2-amd64-20210122 without a problem. I noticed the BIOS
was ~9 years old, so I updated the to most recent version, which is ~5
years old. After the BIOS update, Any FreeBSD boot image I have tried as
far back as 11, no longer boots past the printed EFI framebuffer
information. NetBSD-9 and Kunubtu-20.10 all boot OK. I am not having
success with remote debugging via Firewire (I recall it used to be far
easier), even WITH_LOADER_FIREWIRE, I can still not attach a remote gdb
process. 

My other host which is connected to the E45M1 via Firewire reports when
the E45M1 is booting:

Sorry, please ignore previous reply, the modified sysctl is still
running,
the output earlier, was from the stock binary.

 Yeah I was about to link that.
 To my knowledge this should be fixed but maybe something else is
needed for some different gpu.

If the drive is dying but still working, then using "zpool offline" is
recommended, to tell the pool to stop using the drive.  This is also handy
if there's going to be a delay between "noticed the drive is dying" and
"have a replacement drive available".

If the drive is completely dead, then most likely it will be dropped from
the pool automatically by ZFS, so "zpool offline" isn't needed.

While it's generally "better" to offline drives, ZFS is designed to
withstand drives dropping off without warning.


> Is there a dedicated mailing list for ZFS user questions?

There's a zfs-discuss mailing list run by the OpenZFS project.  There isn't
a FreeBSD ZFS-specific mailing list, but there is a freebsd-fs@ mailing
list for everything filesystem related (UFS, ZFS, mfs, NFS, etc).

Cheers,

When is 'zpool offline' required?

2021-02-08 Thread joe mcguckin

I was just playing around with a test ZFS system and was running through 
replacing a bad drive and I forgot to issue a ‘zpool offline’ command.
Everything seemed to go ok anyway. The system started resilvering, etc. When is 
‘zpool required’? Under what conditions can I omit it?

Is there a dedicated mailing list for ZFS user questions?

Thanks,

Joe

Upgrade 13.0 base OpenSSH to 8.4?

2021-02-08 Thread Michael C
Hi there,

I wonder if it's too late to ask if it's possible to bump openssh in base
to
version 8.4 for 13.0, which enables nist-p256-capable keys and fido/u2f
support.

Despite the fido/u2f capabilities requires libfido2, iirc it is possible to
compile openssh without libfido2 but to enable it in sshd_config,
therefore it is not necessary to add libfido2 as a dependency to base.

Hi,

Maybe you could do a hack and edit the sysctl source code:

1) print the sysctl before it is queried.
2) sleep 1 second between print and query.

Should be easy to nail this down!
