Re: partially invisible back-up DVD.

(fedora-34; gnome)

The evening before doing a Fedora upgrade, I do a user data back-up.  I do it as a data 
project in K3b to burn a DVD/Blu-ray (BD-R).  I always "test" the back-up 
immediately after it's done.

On April 07, 2021, I did such a back-up.  I upgraded from f-32 to f-33 the next 
day.  Today, when I put the disc into the drive, it automatically mounts and 
asks if I wish to view contents in Caja. In Caja, I successfully viewed an 
image stored on the disc, launched in Firefox an html file stored on the disc, 
and opened in LibreOffice a LibreOffice file stored on the disc.  The disc was 
successfully unmounted and ejected when I asked Caja to do so. Also today, if I 
launch Files and then put the disc into the drive, it automatically mounts the 
disc. In Files, I successfully viewed an image stored on the disc, launched in 
Firefox an html file stored on the disc, and opened in LibreOffice a 
LibreOffice file stored on the disc.  The disc was successfully unmounted and 
ejected when I asked Files to do so.

On October 13, I did a user data back-up.  Immediately after, I "tested" the 
back-up.
 1. When I put the disc into the drive, nothing showed up on the screen.  But I 
then launched Disks, the disc was there and mounted; it unmounted and ejected 
the disc when I told it to.
 2. When I launched Files and then put the disc into the drive, the "+ Other 
Locations" flickered once, and that's all.  But when I then launched Disks, the disc 
was there and mounted; it unmounted and ejected the disc when I told it to.
 3. When I launched Caja and then put the disc into the drive, a message popped 
up
"Unable to mount .F33_20211013
An operation is already pending".
But when I then launched Disks, the disc was there and mounted; it unmounted 
and ejected the disc when I told it to.
 4. When I launched Disks and then put the disc into the drive, the icon for the drive 
showed a disc.  When I clicked that disc icon, it showed it mounted.  When I clicked the 
mount path that showed below the graphic part of Disks, it launched Caja.  I then 
successfully completed the "test" just as I did with the April 07 back-up disc, 
except that I had to use Disks to unmount and eject the disk.  Also, I was able to 
restore a files from the back-up disc when using the Caja instance launched by Disks.
I went ahead and upgraded from f-33 to f-34 the next day.

Today, when I repeat steps 1-4 above using the October 13 back-up, I get the 
same results.

Both back-up discs are Verbatum MDISC BD-R Blu-ray Disc, 25GB, 4x speed.  Both 
were written with the same drive.

What went wrong, and how do I fix it?



Sounds like you have an "intermittent" issue with your DVD drive. Dust?  How 
old is the drive?  I've had drives just
slowly die and other just dead after not being used for some time.

I stopped using DVD's and CD's a long time ago.  I only use it if I have to 
boot a live DVD since my motherboard doesn't
support booting from USB.  USB drives are quite inexpensive and more reliable 
than discs with the added advantage of
having higher capacity.  Why not switch?

If it's in a VM, then it can only see the virtual device that the VM 
host is providing which is going to be completely different from the

the real device has to be done in the host OS.

LDAC, AAC, and SBC are options you'd see if the audio HW was bluetooth.  In 
your case, it isn't.  If you want to use BT in a VM
you'd need a BT dongle and you would have to user USB Redirection to give the 
VM access to the HW.

I don't know much about the G533 headset but doubt there are Linux drivers for 
it.  It also connects via the
Unifying Receiver from Logitech, yes?

Not sure why it is this way (counted as shared) but this seems to
confirm that tmpfs is counted as shared:
from the /proc/meminfo documentation:

Shmem

Total memory used by shared memory (shmem) and tmpfs

ShmemHugePages

Memory used by shared memory (shmem) and tmpfs allocated with huge pages

I have been reading the meminfo documentation trying to try to account
for all of the memory usage on a system.

I don't know if there are subtle issues because this is a
memory-based tmpfs filesystem.  But in general, you can see
something like this if a process opens a file and keeps it
open after it's deleted.  The space used by that file isn't
freed until the process which has it open exits (or closes
the file).

You can look for that sort of thing with the lsof command:

sudo lsof -a +L1 /tmp

Maybe that will point to what's taking up the space.

Wikipedia tells us that shared memory is used to communicate between 
programs and between threads in a program.  It's created by shm_open and 
then goes on to say this:


The shared memory created by shm_open is persistent. It stays in the 
system until explicitly removed by a process. This has a drawback that 
if the process crashes and fails to clean up shared memory it will stay 
until system shutdown.


My guess is that one or more of the programs you're using is either 
crashing or is otherwise ill-behaved and not cleaning up after itself.

Growing shared memory leak?

2021-10-26 Thread Jordan Metzmeier
I am trying to determine if a problem I am experiencing is a bug or if
there is something I am missing. Last week I found that 15GB of my
32GB RAM was used by shared memory, causing my system to fill swap.
After about 1hr of trying to discover the reason for this, the only
thing I could find was that `df` was indicating that space was being
used by tmpfs mounted on /tmp, but I could not find files that came
anywhere close to this size.

Now I am inspecting my system after a few days of uptime and have
found that shared memory is slowly growing again. It's currently up to
almost 4GB:

jmetzmeier@localhost:/tmp $ free -m
  totalusedfree  shared  buff/cache   available
Mem:   32065949321853920   20386   18204
Swap:   819121146077


When I check df, what's reported as used on /tmp is pretty close to my
shared memory usage:

jmetzmeier@localhost:/tmp $ df -hT /tmp
Filesystem Type   Size  Used Avail Use% Mounted on
tmpfs  tmpfs   16G  3.5G   13G  22% /tmp

However, `du` does not show 3.5GB of files inside:

jmetzmeier@localhost:/tmp $ sudo du -sh ./
32K ./

Does anyone know what could be happening here? Does writing a file to
tmpfs and then deleting it cause the tmpfs to retain that allocated
memory until reboot?

My system is running Fedora 34. I have ensured nothing is mounted over
top of /tmp and hiding files.

Thanks,
Jordan Metzmeier

Debugging USB device issues

2021-10-26 Thread Philip Rhoades via users

People,

I didn't get a response to my previous Q re an apparent problem with 
getting gphoto2 to work with my GoPro Hero 4 Session camera - I hadn't 
used the camera for a while and I thought maybe the Fedora upgrades 
since then were the cause of the problem - but maybe the problem is 
actually with the USB port on the camera? (gphoto2 used to work).  The 
camera actually charges OK through the port and I can record videos and 
then move them to Fedora by moving the SC card to a card reader, 
mounting the dir and copying video files to the HD so the camera itself 
and device charging seems to be OK.


I am getting nothing recorded in /var/log/messages when I plug in the 
GoPro and push its power button (plugging in any other USB device is 
working of course) so maybe it is the USB port on the camera that is the 
problem? - is there any way to debug that from the Fedora workstation?


Thanks,

Phil.

Or, as I often suspect, the devs are thinking, "We don't use that so 
there's no need to provide it."

partially invisible back-up DVD.

2021-10-26 Thread home user

(fedora-34; gnome)

The evening before doing a Fedora upgrade, I do a user data back-up.  I 
do it as a data project in K3b to burn a DVD/Blu-ray (BD-R).  I always 
"test" the back-up immediately after it's done.


On April 07, 2021, I did such a back-up.  I upgraded from f-32 to f-33 
the next day.  Today, when I put the disc into the drive, it 
automatically mounts and asks if I wish to view contents in Caja.  In 
Caja, I successfully viewed an image stored on the disc, launched in 
Firefox an html file stored on the disc, and opened in LibreOffice a 
LibreOffice file stored on the disc.  The disc was successfully 
unmounted and ejected when I asked Caja to do so.  Also today, if I 
launch Files and then put the disc into the drive, it automatically 
mounts the disc. In Files, I successfully viewed an image stored on the 
disc, launched in Firefox an html file stored on the disc, and opened in 
LibreOffice a LibreOffice file stored on the disc.  The disc was 
successfully unmounted and ejected when I asked Files to do so.


On October 13, I did a user data back-up.  Immediately after, I "tested" 
the back-up.
 1. When I put the disc into the drive, nothing showed up on the 
screen.  But I then launched Disks, the disc was there and mounted; it 
unmounted and ejected the disc when I told it to.
 2. When I launched Files and then put the disc into the drive, the "+ 
Other Locations" flickered once, and that's all.  But when I then 
launched Disks, the disc was there and mounted; it unmounted and ejected 
the disc when I told it to.
 3. When I launched Caja and then put the disc into the drive, a 
message popped up

"Unable to mount .F33_20211013
An operation is already pending".
But when I then launched Disks, the disc was there and mounted; it 
unmounted and ejected the disc when I told it to.
 4. When I launched Disks and then put the disc into the drive, the 
icon for the drive showed a disc.  When I clicked that disc icon, it 
showed it mounted.  When I clicked the mount path that showed below the 
graphic part of Disks, it launched Caja.  I then successfully completed 
the "test" just as I did with the April 07 back-up disc, except that I 
had to use Disks to unmount and eject the disk.  Also, I was able to 
restore a files from the back-up disc when using the Caja instance 
launched by Disks.

I went ahead and upgraded from f-33 to f-34 the next day.

Today, when I repeat steps 1-4 above using the October 13 back-up, I get 
the same results.


Both back-up discs are Verbatum MDISC BD-R Blu-ray Disc, 25GB, 4x 
speed.  Both were written with the same drive.


What went wrong, and how do I fix it?

Thank-you in advance.
Bill.

This reply is going through the router.


It could be that *your* modem and/or router doesn't need power cycling,
in general, but that it randomly goofed and needed it this time.

You can test that.  Unplug its data leads, leave it powered up.  Some
time later, repatch it, and see if things just work.


By "repatch", you mean reconnect, right?
Next time I check for ipad OS patches/upgrades, I'll try what you 
suggest.  That's done monthly.



It may also depend on things like; do you leave your modem always
powered?

Some people leave everything off, and the individual lengths of time it
takes for their modems and routers to boot up means that things always
work for them, or randomly don't work.


The tower is powered down nightly.
The router is powered up only when I need it, which seems to be once a 
month.  (My other uses of the ipad do not need the internet.)
The modem is an Arris phone modem, so it's always on (for the land-line 
phone).


Thank-you, Tim.

Bill.

This is intentional.  In order to make thumbnails, it would have to
read the entire files from the device over the slow MTP link.  Most
people would be very unhappy about that because they wouldn't be able
to do anything else until everything is read from the phone.

The same can be said about other networking protocols, which is why we
had options to display them, or not, and let us make the choice about
consequences.

Trying to find a photo from a phone is a pain, they don't have useful
filenames.  You've got to go trawling through them all to find
something.  If you're organised, you might move photos into sensible
folder names as you go along.  And you might decide that it is worth
turning on thumbnails to find the specific photo out of 20 from last
week's birthday party.

If you read the context in the gitlab issue I posted, basically performance is 
terrible when previews were being generated. Someone complained (back when it 
was originally filed) that it should be controlled by a setting and the 
Nautilus/gvfs developers chose not to.

The only way it’ll be switched back is to open a new issue, perhaps with a 
merge request with code improving the threading performance enough to make 
thumbnails not bring the whole interface to a stall.

Again - this should be given back to users that executive 
decision - which I'd advocate for - whether or not users 
want/need thumbnails off their Android phones.
Problem in the past was not - if I remember correctly - that 
transfer was slow. It rather was that the whole system would 
"freeze" what such transfer took place.
It really could be simple - "Show Thumbnails = All files" 
does what is says OR expand with one extra entry "All files 
excluding USB Phone".
Anything really, but don't keep users in the dark .. perhaps 
because they are all simpletons and devs know better.

many thanks, L.
ps. how can a user file such a request, in Bugzilla?
