You can still have this with subvolumes. See btrfs-quota(8).

The quote describes a situation which has gone for more of a decade now. Since 
we have LVM (when got that part of the Linux kernel? kernel 2.6? 2004 or so? 
Don’t know exactly), no one would partition a hard disk along file system 
subdirectories. You create logical volumes instead, which can easily "changed 
without a reinstallation“ and space for any logical volume "can be expanded
or restricted on the fly“. The latter even easier with „thin provisioning“. And 
of course you can do backups and restores via snapshot, it's called LVM 
snapshot. What a surprise.

And you can do all that without that "subvolume (only) looks like its own 
filesystem“ but in reality are not separate and independent filesystems but 
merely pretend to be.

BTRFS has specific advantages, without a doubt. And it is attractive for 
specific use cases. But it's not a silver bullet against all the tribulations 
of file storage, nor is it the only way to the future of IT. And by far it is 
not the almighty system, which fits everything as default,  as many "BTRFS 
missionaries" would have you believe, throwing buzz words around.

Yes, a sentence beginning with „You can have this with ….“ is probably true for 
every IT topic. 

The question is rather whether you can realistically have it in everyday 
practice. 

Workstation WG made BTRFS default with F33. Even now with F35 one year later, 
where is easily accessible documentation for a user who wants to install 
Workstation? Neither the current Installation Guide nor the Administrator's 
Guide give any information about how to handle BTFRS. The complete text is up 
to date with Fedora 25 or perhaps a bit later, only minimally updated to 
subsequent versions. 

And I see no Workstation doc listet on docs.fp.o, unlike the other Fedora 
editions, again, after a year.

And is there an adapted installation step in Anaconda to expose an option to 
set a max. limit (e.g. like to handle the root login - deactivated, key only, . 
. .) and probably some other valuable capabilities? I can’t remember to have 
seen something like that.

Therefore, a user is dependent on clear and informative terminology. And, well, 
sub-„volume“ after 32 Fedora releases has a specific meaning. 

(And that is one of my issues with those „missionaries“ who fight about their 
principles, but don’t care about their flock)

I've been using BTRFS for several years now and it suits me. I could
never get my head around LVM and considered it overkill for what most
workstation users need, but that's a matter of personal taste.

I am still using EXT4 partitions (via manual partition setup) for F35 on 
my notebook for /boot, /, and /home:


temp stuff deleted.

/dev/sda2    69G   27G   39G  42% /

I've still got plenty of room on my 500GB SSD drive, so I am not 
concerned about space.  Perhaps with F36 (or F37 if I skip), I will try 
and see if btrfs gains me anything for possible performance loss.


Oh, in /home/common/ietf I have ALL RFCs and drafts! (over 138K

laptop failing with latest kernel update

2022-02-08 Thread Anil Felipe Duggirala
hello,
I performed a normal update today after some time without updating, which I 
believed contained a kernel update (to 5.16.5-100.fc34.x86_64 I believe). After 
doing the update and rebooting my pc started behaving erratically. Bootup time 
was longer, then it sort of got stuck, then some problems were reported by the 
reporting app in Gnome. My computer was simply malfunctioning all over the 
place, sometimes freezing completely. Decided to boot to the previous kernel 
(5.15.16-100.fc34.x86_64) and my pc is back to normal. 
The Reporting app does not let me send a report saying 
"The backtrace does not contain enough meaningful function frames to be 
reported. It is annoying but it does not necessarily indicate a problem with 
your computer. ABRT will not allow you to create a report in a bug tracking 
system but you can contact kernel maintainers via e-mail."

How should I report this issue in this case?
How can I change the grub boot default for now to boot to the older kernel by 
default? or should I try reverting (removing updated kernel) to the older 
kernel altogether for now?

thank you,

Anil F

I used to do the same, having to manually partition because the default
setup was LVM. However I prefer BTRFS because a) I don't have to guess
what size of partitions to create at install time, something which is
difficult to change later, and b) BTRFS includes features such as
snapshots and built-in RAID without having to deal with an additional
layer as with LVM.

Again, it's a matter of preference.

Exactly!  I tried using thin provisioning once as a way to solve the 
"how much in / and how much in /home" dilemna and ended up regretting 
it.  There is no indication of how much space is really available and 
when it ran out, it was messy.  At least btrfs gives you an accurate 
number even if it might be a little confusing at first why / is getting 
so small when you fill up /home.

Yes, (open)SUSE enables qgroups by default for years. Fedora doesn't
enable them, but it's worth checking out 'man btrfs quota'. They're
pretty cool, and the docs consider the dilemmas raised by snapshots,
and how that affects accounting. There are some performance concerns.
Desktop users don't need to worry about it, you can enable them, play,
disable them. The whole quota btree is removed, no residue remains on
the file system.

?

https://docs.fedoraproject.org/en-US/fedora/f35/install-guide/install/Installing_Using_Anaconda/

Those are Fedora 33 screenshots. "btrfs" appears 34 times in the
document. There's an entire section on creating a btrfs layout.
https://docs.fedoraproject.org/en-US/fedora/f35/install-guide/install/Installing_Using_Anaconda/#sect-installation-gui-manual-partitioning-btrfs

Since I wrote up the lightweight changes for docs when btrfs became
the default, I'm aware that the documentation has weaknesses. It is
still LVM centric, and doesn't have hints for Btrfs nuances.

In particular, with how to get the installer to reuse the "home"
subvolume for the /home mountpoint. It is super easy to do, but
totally non-obvious. The part most folks run into is not reusing
"home" subvolume itself, which is just a matter of clicking on the
previous installation "home" and assigning it to the /home mountpoint.
But rather how to install to / because it won't let you reuse the
"root" subvolume. This is due to the installer requiring a new clean
filesystem for root. Ext4 and XFS require reformat, but Btrfs gets a
partial exemption. You don't have to reformat, but you do need a new
"root" subvolume, so you just create a new mountpoint with the +
button, specify the mountpoint as /, and leave the capacity field
blank. It'll add / mountpoint *and* create a new subvolume in the
process. You can either delete the old "root" subvolume, or keep it -
it's a matter of space available but as all subvolume share space it's
a pretty simple calculation whether you have room for it or not.

Workstation is a different installation experience than Server.
Workstation does a Live install, using rsync, and users are setup in
GNOME Initial Setup rather than in the installer.

There are only so many words.

I'm reminded of the word "chunk". You see this word quite a bit in
computer storage. If you specialize in one thing or another, you might
get the idea that chunk is a specialized word that has a pretty
specific meaning. And then you're surprised when you come across that
same term in another context, it means something quite different.
Chunk in mdadm is what the SNIA dictionary calls "strip" or "stripe
element" [1] On Btrfs, chunk is a different thing entirely, there's no
SNIA equivalent term. So it's certainly easy to get confused when
terms get reused.


[1] can you believe those two terms are synonyms?[2]
[2] part of the problem might be the English language, really. If
you've ever been confused about strip and stripe [3], it's not you,
it's the words themselves.
[3] These two terms are not synonyms. [4]
[4] It really could make you a bit bonkers. I've really digressed now.

2022-02-08 Thread Alex
Hi,
I have fedora35 installed on my desktop with a Radeon RX 570 driving
three monitors, with the Cinnamon desktop, although it could be the
other variation of Cinnamon that's available by default - I checked
the Settings menu and can't find any way to determine which it is. I'd
like all three monitors to turn off after 15 minutes of inactivity.
What is the best way to do that? Simple question, but clearly not a
simple answer.

I'm an old-school admin from a time when we had to build our own X11
config files. I just expect things to work now, so I haven't really
kept up with the desktop, even though fedora and whatever graphical
display it provides by default has been my primary desktop since
before Windows XP.

Now, when I set the "turn off the screen when inactive for" option to
5m in the Power Management settings, I find that it takes far longer
than five minutes for it to actually turn off the monitors, but then
not only do they all immediately turn back on, but all of the windows
on the middle monitor are shifted to the two left and right monitors.
wtf? It's incredibly frustrating to have to reposition all windows
back to their original location.

How do I troubleshoot this?

Hi,

I suspect there are multiple issues you are experiencing, and some of
them I have for a long time, totally unrelated to the desktop
environment used and distribution.

I'm also experincing issues with display power management not working,
I don't know which one it is really and do these match with the issues
you are experiencing, but one thing is common and that is AMD graphics
card (here: AMD Radeon RX 550 / 550 Series (polaris12)) and there are
some known issues with them waking up displays[1][2] (at least what I
found, could be unrelated, I gave up when I saw for how long they
exist).

I mostly use other desktop environments (Gnome and KDE) both with
wayland session, and they had their own issues when they lose a display
(output) things were crashing ..., but that is now improved. But still
I see issues with applications move to other display after display goes
to sleep and returns. (also experienced same issues with XFCE).

Not helpful really, but just my rant about it since I have those issues
for some time now.

Regards,
Branko
