Hello Altoid,

Thank you for your hint.

With the expression "ENOSPC" (Error: No space left on device) on the the 2nd link, I found a german page that seems to fit to my problem:

https://www.slicewise.net/debian/balanc … eisystems/

According to that it couldbe that btrfs "thinks" the partition is full, bit it isn't.
Caused by btrfs not realesing space that is not needed any more. (it is actually more complicated than that)
To solve the problem the size of the blocked partition could be temporary increased, that there is enough space for btrfs and then balance the fs again:

cd /mnt
mkdir fulldisk
#the "full" btrfs-partition is /dev/sda2
mount /dev/sda2 fulldisk
#add a USB-stick to the 'full' btrfs partition
btrfs device add /dev/sdb fulldisk
#balancing
btrfs balance start fulldisk
#remove USB-Stick from btrfs-partition 
btrfs device delete /dev/sdb fulldisk

Well I tried this with the stick that was plugged in wit an antic Live systemand forced the add as I need not the data on the stick any more.

But something went wrong. Wether I could run the balancing nor could I remove the stick from the btrfs-partition.

I did a reboot and now the "full" btrfs-partition could not be mounted any more. Also when I try to start a btrfs repair action it aborts with the error message:

 root@blechdepp:~# btrfs check --repair /dev/sda6

Error:

Chunk[256, 228, 37606129664]: length(1073741824), offset(37606129664), type(1) is not found in block group
well this shouldn't happen, extent record overlaps but is metadata? [37339414528, 16384]
aborted

It seems it is time ti format /dev/sda6.

Or is there another option?

Would it be wiser to change to ext4 fs instead of btrfs?

I have the following problem:

according to df my home directory has free space and is fully occupied the same time:

/dev/sda6        40G     29G     0  100% /home

This is permanent and does not disappear after a reeboot.

Withe the help of ddg-ai I made a few checks and also tried a repair but was not successful.

Here the results of the checks:

@fsmtihred:
Thanks for the hint, indeed by removing grub-efi-amd64-signed, the problem disappered. The prefix is now set to another value where also the grub configuration files are saved after another:

grub-install

matze72 · Hardware & System Configuration

I had the same problem that viverna had. But in my case grub-efi was already installed, beside grub-pc.
Deleting grub-pc and reinstalling grub-efi (I reinstalled grub-efi common and grub-efi 2 common) did not solved the problem.

Later I found ot that it is the prefix that causes grub to enter the shell/rescue mode.

It is set to .../efi/debian.

As soon I change it in the rescue mode to .../efi/devuan I can enter normal mode and the system starts normally.
This fits to the directories found in /boot/efi/EFI/.

I could not find a method to change the prefix presetting. The only solution I found was to force grub to install itself under .../efi/debian with

grub-install --bootloader-id=debian

Could it be that in one of the last updates the change of the prefix from debian to devuan has been forgotten?
Or that the directory name has been changed without changing the prefix?

I can reproduce this error. You need to start jack or set audacity to use alsa. (or maybe pulseaudio if you use that.)

Thanks for the answer.
I figured out that the problem has been caused mainly by a setting of audacity.
I had to uncheck the "SW playthrough of input" option. This caused a feedback loop and therefore causing a saturation of the signal.

This is also mentioned here in the PulseAudio section:
https://manual.audacityteam.org/man/tut … linux.html

Following this and some of the recommendations here (https://www.freedesktop.org/wiki/Softwa … fectSetup/), where I am not sure if the later ones were really necessary, solved the problem.

Hello,

I have severe sound problems with audacity.

When I start a recording, it can happen that the sound i would like to record it suddenly very disturbed, that it is hardly recognized any more.
As soon as I stop the audacity recording the sound problem disappears.
The same disturbance can happen during playback with audacity.
But this happens not all the time. Sometime it just works fine, sometimes I just got dropouts during in the recorded data.

This is the printout in a shell after I started audacity, there are quite some errors/warnings but I do not have a clue if they are related to the problem or not.

Does anybody have a hint what I could do to solve the problems?

No, allow-hotplug did not make the trick. Nothing changed.
Ethernet cable is also plugged in all the time.

@Lars

I have not the impression that sysv-rc-conf is broken.
And I did this when I still used ascii and did not change it.

I also have the impression that first connman is started and then the networking service, is there an easy way to check this?
I guess it is somewhere in the init scripts at /etc/rc.... , can I just adapt the names to force a different order?

For example change K01connman to K09connman to make sure that the connam service is started after K07networking is starting the networking service, or can I break something doing so?

matze72 · Installation

@Lars

I used sysv-rc-conf to define the following:

service 1 2 3 4 5 0 6 S
connman [ ] [x] [x] [x] [x] [ ] [ ] [ ]

I believe that this should do the same as update-rc.d connman enable, isn't it?

matze72 · Installation

@Vernon:

Sorry the path was a typo, indeed my interface-file is at /etc/network/interfaces.

Do you think the "allow-hotplug" is making the difference, or have you additional files in your interfaces.d-directory?
Mine is empty.

I will try the allow-hotplug.

Thanks,

After ugrading from ascii to beowulf I came across some problems, for some I could find solutions or workarounds on my own, for some not.

But let's start with the main problem:

1) After the upgrade I did not have internet access any more. It turned out that no dhc clinet is runing. After I added the following lines to /etc/interfaces
auto eth0
iface eth0 inet dhcp
dhclient is running after booting, but I still have to restart connman with the following command to get access to the internet:
service connman restart
How can I fix this?

2) During booting the boot process stops for some minutes at Starting MTA. Is there a possibility to avoid this?

3) There must be change in the firejail profile file firefox-common.profile that caused problems with my firefox installation. is there a way to download the ascii version of that file to make a comparison?

4) The directory /usr/sbin was not part of the PATH variable any more, at the moment I use the following command as root after boot:
export PATH=/usr/sbin:/sbin:/usr/local/sbin/:$PATH
How can I define this permanently?
Do I have to include this in .bashrc in the root home directory or is there a system wide configuration file?

5) After the upgrade I do not have the possibility any more to send the computer into "sleep mode" with obsession-logout, does anybody know a reason for that?
Can this be caused by the upgrade hint to downgrade upower because of a bug (and I followed that hint)
