The AWS freebsd-update has been working fine for quite a while.  All
project mirrors are slow in Australia so we have been using the AWS one
since Colin brought it online to make it a better experience for our team
to update the fleet.

FWIW adjust update.FreeBSD.org to aws.update.FreeBSD.org in
/etc/freebsd-update.conf and you are good to go.

Can the project look at offering traditional mirrors for base and pkgs
rather than the current offering?  Those that want to stand up un-official
mirrors can do so by pointing rsync to a Tier 2 mirror for updating
purposes so they can provide faster, localised access.  From Melbourne to
our closest geo mirror is 240ms, this latency really drags out updates, so
having a mirror out of a Melbourne DC would be beneficial.

Cheers,

Jason.

I've taken update4 out of the SRV record for the time being since it was 
doing more harm than good.

The 10Gbit uplink of my university, directly connected to the

I'd always use that and updates were really fast back then.

Now that update3 is gone all update servers seem to be in the US or 
Australia.


After waiting for nearly one hour:

This is getting kind of tiresome. :(

There seems to be a problem with update4.

I now have this, too.

It looks like there were at least experiments with pointing 
freebsd-update at AWS, similar to how portsnap currently works.  I will 
check if these experiments went anywhere and possibly point 
freebsd-update there instead.


I believe the problem with update4 is load-related.


:-(

I would rather just mirror the update server but I think this is not 
supposed to be done?


I think you can set up your own freebsd-update servers, but that won't 
fix this problem.


I'll see what can be done to fix this.

Watch this space.

Did you try aws.update.freebsd.org also?

geli - is it better to partition then encrypt, or vice versa ?

ZFS on FreeBSD has never had this issue, and has fully supported the use of
partitioned disks from the very first import of ZFS into 7-Stable.

No other OS that supports ZFS has this issue; it's strictly a Solaris (and
derivatives) issue.

IMHO one reason to partition first (and the reason I do it) is to 
prevent "drive attachment point hopping" from causing an unwelcome 
surprise if/when there is a failure or if, for some reason, you plug a 
drive into a different machine at some point.  If you partition and 
label, then geli init and attach at "/dev/gpt/the-label" you now can 
label the drive carrier with that and irrespective of the slot or 
adapter that gets connected to on whatever machine it will be in the 
same place.  If it fails this also means (assuming you labeled the 
carrier) you know which carrier to yank and replace. Yanking the wrong 
drive can be an unpleasant surprise.


This also makes "geli groups" trivial in /etc/rc.conf for attachment at 
boot time irrespective of whether they physically come up in the same 
place (again typically yes, but in the case of a failure or you plug it 
into a different adapter.)

The answer depends on why you want to partition in the first place.  What
do you intend to store on those disks besides ZFS?  If the answer is
nothing, then don't bother partitioning; just write ZFS over GELI over the
whole disk.

(Also, it's worth asking why you want GELI, now that FreeBSD 13 supports
ZFS native crypto.  ZFS native crypto on RAIDZ has substantially better
write performance than RAIDZ on GELI.  However, if you're paranoid, then
GELI does provide better security; ZFS native crypto is vulnerable to some
kinds of watermarking attacks.)

I encrypt the whole disk and then add it to the pool. No need to partition it. 
If I remember correctly zfs prefers unpartitioned disks.

There seems to be a problem with update4.

I now have this, too.


I’m cc-ing clusteradm and dnsadmin, in hope that there’s somebody there who can 
either fix it or take update4 out of the srv record…


:-(

I would rather just mirror the update server but I think this is not supposed 
to be done?

13.0-RELEASE bsdinstall failure : looked for MANIFEST in wrong place (not with *.txz files)

[Mark Millard via freebsd-stable]

Booted RPi4 via micrsd card dd'd from:
