Both made well, but zfs has 128 bit checksums, and many other features which takes ticks
Jay
Zfs is memory hungry (due to arc cache) and in general it is more complex meaning more slower
You can limit the ARC size
Denis
Sure. And turn off all features. But why not just use ufs then?
Denis
Features like checksums
Denis
You will just get quite handy volume manager
Denis
But if you dont need it - ufs

What would you recommend for my laptop ?
Its an i5 kabylake U processor with 16 GB ddr4 ram
And I'm going to put freebsd on a second 256gb nvme
Phil
But in the documentation of postgres they talk about some lacks that depends on the choice of UFS and ZFS .. and I don't understand why it takes effect
Phil
@Pascal3366 I always choose the minimalist softwares, in your case if you wanted to use this disk as backup disk with mirroring use ZFS it's made for, otherwise use UFS it's simple. By the way, OpenBSD choose to not develop ZFS due to its many features. To sum up if you use it for cloud purpose ZFS, otherwise....

If performance is the issue - ufs, if this is just for testing/fun - zfs, because it is a pleasure to use it

It is just hard to implement, i think they just gave up
Denis
Aren't cddl bsd-friendly?
Phil
It wasn't for the license but more for the simplicity

Well on my server I have a 4tb iron wolf pro as nas storage with zfs, but no redundancy so far
On my notebook I will just have that 256gb nvme ssd
Phil
on notebook use UFS; on the nas use ZFS; if you want to add HA on the nas then add new disks and start mirroring. Be aware there exist many types of mirroring the first one is on two disks, but exists another method on three disk where it's more optimized for. Cause it will only use 30% instead of 50%. I think it's called RAID (I'm not sure).
Phil
Maybe I m wrong about this type of choice, but that's what I m thinking about...
Jay
I see no problems running ZFS even on smaller devices
Jay
Got it running on 1gb and 2gb VPSes
./pascal.sh
Mh my server is updating ports since a few hours now
It seems that it even now pulls stuff from ports it did not before
Is that normal ?
./pascal.sh
I am installing llvm through ports currently
I can't remember that I installed that through ports

Raid 0 is extending
Raid 1 is mirroring
The other raids use more drives for parity for example and other integrity

Llvm on freebsd is a heresy, use geom
./pascal.sh
Llvm on freebsd is a heresy, use geom
I did not even know that I had it installed
It takes really long to compile
But I guess that it's a dependency of some package
Denis
Confused with lvm, sorry. Yes, some fresh ports needs a fresh clang/llvm. Those are build dependant mostly - so you can install built binaries using pkg temporary
./pascal.sh
mh so upgrading the ports did not work
it failed with
meson.build:319:4: ERROR: Problem encountered: No platforms specified, consider -Dplatforms=drm,x11,surfaceless at least
A full log can be found at /usr/ports/graphics/mesa-libs/work/mesa-19.0.8/_build/meson-logs/meson-log.txt
./pascal.sh
i don't even know why mesa got pulled
there is no graphical stuff installed at all
./pascal.sh
mh my syncthing daemon is still eating up over 100% cpu usage all the time
./pascal.sh
Mh okay i changed the scan Interval now to hourly
Hope that will be better
./pascal.sh
ok now cpu usage is between 5-15%
thats ok
Anonymous
it does fetch update n install
./pascal.sh
Ok
Anonymous
sorry....typo.... it's portsnap auto...my bad
./pascal.sh
sorry....typo.... it's portsnap auto...my bad
OK did that
Nothing happened but I guess that I already updated everything

Nice I just saw that my Thinkpad T580 has full freebsd support, according to the wiki
./pascal.sh
Nice my 256gb 2242 SSD just arrived
I am going to install that later in my thinkpad and install freebsd on it
./pascal.sh
Can someone tell me how I can get my kabylake graphics to work?
Arminio
Nice my 256gb 2242 SSD just arrived

What Thinkpad exactly do you have?
./pascal.sh
its an i5-8250u if I am correct
Arminio
Can someone tell me how I can get my kabylake graphics to work?
Probably just installing drm-kmod, maybe you have to add to add something like this here to rc.conf:
kld_list="/boot/modules/i915kms.ko"
./pascal.sh
Intel uhd 620 graphics
Arminio
Hi Pascal. :)
./pascal.sh
Hi :)
Arminio
Yeah that sounds good. Could work.
Arminio
It's not unlikely that you will have zero problems. :)
./pascal.sh
So drm-kmod is installed
And I added
kld_list="/boot/modules/i915kms.ko" to /etc/rc.conf
Arminio
Are you used to running FreeBSD on desktops already? There are some awful things you have to know.
./pascal.sh
It's not unlikely that you will have zero problems. :)
Well I heard freebsd 12.1 would run with kabylake graphics. Its written in the freebsd wiki
Arminio
So drm-kmod is installed
And I added
kld_list="/boot/modules/i915kms.ko" to /etc/rc.conf
PROBABLY you just need to throw your user in the video group and reboot then (I guess?)
./pascal.sh
Are you used to running FreeBSD on desktops already? There are some awful things you have to know.
Well I ran freebsd 11 on my old laptop a few years ago
That was a skylake graphics card and freebsd had no real skylake support at that time
But I got it running using drm-next-kmod
Arminio
Well I heard freebsd 12.1 would run with kabylake graphics. Its written in the freebsd wiki
Yeah but I still consider it great luck when finding out the hardware I happen to have DOES actually work with FreeBSD.
./pascal.sh

I am already in the video group
Arminio
./pascal.sh

According to the wiki
EVERYTHING in my t580 works
Arminio
Except the bluetooth thing I guess?
Arminio
oh wow
./pascal.sh
Mh am I missing something ?
So in my /etc/rc.conf I have
kld_list="/boot/modules/i915kms.ko sysctlinfo cuse utouch"
./pascal.sh
And xorg seems to work because if I run startx with default options I get terminals and a 1080p resolution
Arminio
Sounds fine to me
./pascal.sh
Uhm OK startx does not work anymore
./pascal.sh
oh OK
module i915kms does not exists
./pascal.sh
That should be "intel" right?
Arminio
Are you sure? /boot/kernel/i915kms.ko should exist.
./pascal.sh
But in the xorg log it says
Module does not exists
./pascal.sh
Oh wait I did not have
i915kms_load="YES"
In my /boot/loader.conf
Let's try that and reboot ....
Arminio
Ah that, yes
Arminio
That rings something
./pascal.sh
Nope
./pascal.sh
i915kms is still not found
Arminio

These here are my notes for installing FreeBSD on an X220, I believe most of the steps should be identical to your setup
Arminio
kSo maybe that helps you :)
