For your rtl8812au, I was able to track down
https://github.com/morrownr/8812au-20210629

For your rtl8822bu, https://github.com/morrownr/88x2bu-20210702

I'm not sure what kernel version you're running (on Fedora 37 I'm running
6.1.13) but it might be worth a shot, if you haven't tried either already?
They seem to have been updated fairly recently.

Might be worth asking the maintainers to get them into the kernel itself,
though...

I thought we were talking about the resulting VM, because it would be difficult 
to build a 32-bit p2v when the 64-bit Fedora kernel/userspace can’t boot on a 
32-bit only CPU. 

I suspect the tool to make the p2v boot disk requires building all the 
dependencies as 32-bit executables and libraries and most of those are no 
longer included in Fedora repos. The instructions indicate it would be time 
consuming:

https://www.libguestfs.org/virt-p2v-make-disk.1.html#bit-virt-p2v

Might be easier to just pull the disks and dump the disks to a file.

Agreed, but there are 56 threads on this machine. So, if all of them are being 
used, then the amount of memory is not that much on the average, though I hope 
to be fine.

I currently have a 8y-old 10C (20 thread) machine (originally with 32 GB, went 
up to 64 GB). At least for some jobs, I was not able to use all threads because 
of memory requirements. For that machine, I have:

$ swapon NAME   TYPE   SIZE USED PRIO /dev/zram0 partition8G   0B  
100 /dev/sdc6  partition 46.6G   0B   -2

and

$ free
   totalusedfree  shared  buff/cache   available
Mem:65762928 108965661769992   30928 2903280
63914968 Swap:   57215992   057215992

so I guess there is the zram0 there. 

I also don't see much value in having a lot of swap, unless it is some sort of 
very short (to be useful) holding operation (that is how my layman's mind likes 
to think about it).

And set swappiness to something low, like 1. There's almost no reason
to allow anything to spill into the swap file with 512GB of RAM.

In fact, my daily driver has 64GB of RAM, and I set the swap file size
to 4 GB and set swappiness to 1. The 4 GB swap is there for
emergencies, but I don't think it's ever been needed.

Thanks! So, at this point, I will simply increase / to cover around 250 GiB: my 
plan is to simply copy the first drive to the second for backups.

Btw, my sysadmin tells me that he bought 3 4 TiB drives and put it on the card. 
But during installation, I see only one 4 TiB drive. Is this possible? (These 
HDDs/SSDs are not RAIDed.)

Re: recommended partition for swap with 0.5 TB memory

2023-02-28 Thread Roger Heflin
if whatever you are running on said machine is going to be useless if
you are swapping you don't need much swap.  The apps I deal with if we
get much into swap has severe performance issues and is basically in
an outage.

I have 72core/1TB ram and have 30GB of swap (pre zram os)   The
reality is if we are swapping then something/someone screwed up (too
many process, process leak, memory leak, machine sized wrong).

With zram you set a maximum amount of memory which can be used as swap (I
think the default is 50% but it may have a maximum set). How it works is
that it compresses the memory, generally giving around 2X compression. The
CPU cost to compress/decompress is much faster than swapping to disk,
perhaps not as much with modern NVMe drives, but it does help relieve
memory pressure without causing unnecessary writes to your expensive SSDs
:)

I was hoping to find something more Fedora centric, but here's the upstream
documentation:
https://github.com/systemd/zram-generator/blob/main/man/zram-generator.conf.md

I decided to let the automatic installer pick up the partition. It correctly 
sets aside 4 TiB (sorry, it was 4TiB, not 2TiB as mentioned earlier) for /home, 
and then 1 GiB for /boot, 600 MiB for /boot/efi, 70 GiB for / and leaves aside 
the rest (as free space). I can adjust the 70 GiB, but do I need to keep aside 
space for the zram? I am unsure about what to do with so much free space?

Right, thanks. So, I let the installer pick this up. I usually do a custom 
partitioning, does that mean that I do not declare anything for swap?

Thanks very much!

Best wishes,
Ranjan

By 0.5TB you mean 512GB of ram? Assuming you're installing Fedora 36 or 37,
I would just leave the defaults alone, which utilizes swap on zram. So
basically it won't use any swap unless needed. You can adjust the amount of
memory allowed to be used for swap.

Thanks,
Richard

recommended partition for swap with 0.5 TB memory

2023-02-28 Thread Ranjan Maitra
Hi,

I am trying to install Fedora on to a new machine that has 0.5 TB RAM. Hard 
drives are 256 GB for / and friends, and 2 TB for /home partition. In the past, 
it used to be suggested that swap be twice that of RAM: this later changed to 
the same amount, and now it is very unclear (to me) because I have not tracked 
the latest recommendations. Anyway, what would you suggest? The machine is a 
Dell Precision 7920 with 28 cores/56 threads.

Many thanks for any suggestions, and best wishes,
Ranjan

gthumb crash on startup and bugzilla reporting

2023-02-28 Thread Max Pyziur


Greetings,

I occasionally forget to shutdown gthumb before shutting down my pc.

On startup of the PC, I see a message indicating that gthumb crashed and 
asking whether or not I want to report the bug.


(This is more of a nuisance; I can always start gthumb, and it works very 
well.)


I click yes; the process runs, downloads debug packages, etc. When it is 
ready to report, send in the information, I get the following message:

Backtrace is generated and saved, 145368 bytes

--- Running analyze_BodhiUpdates ---
Looking for similar problems in bugzilla
fatal: RPC failed at server.  The API key you specified is invalid. Please 
check that you typed it correctly.
abrt-action-find-bodhi-update [ERROR] Search for duplicate bugs failed: 
None

('analyze_BodhiUpdates' exited with 2)


###

So, I would like to complete this process; I have bugzilla credentials; do 
I apply them somewhere in this report? Or do I have to acquire other 
credentials for this API?


Thank you,

Max PYziur

That fixed it for me when I had this issue a while back. Worth a shot.
