BTRFS partition corrupted after deleting files in /home
by Sreyan Chakravarty
Hi,
I don't know what happened, but I just logged into my system and
deleted some unused files in my home directory. Just some directories.
Suddenly everything on my system became read only. While rebooting I
think I saw messages like:
"BTRFS Error"
I booted into a live environment to restore my snapshots, then while
mounting the BTRFS root partition I got:
mount: /mnt: wrong fs type, bad option, bad superblock on
/dev/mapper/dm_crypt, missing codepage or helper program, or other
error.
I don't know what to do, my system won't boot.
Why is BTRFS so unstable ?
Please don't tell me to erase everything and start again. that is not feasible.
Is there any other way?

btrfs: What to do with large growing files?
by Richard Shaw
So from what I understand once a file is >0 that you can't set nodatacow.
I'm playing around with cryptocurrency and the current one downloads the
whole blockchain and it's at 65GB and growing. I think the growing part is
the problem. That and it's being stored on /home which is a spinning disk
not an SSD like the system disk.
I'm seeing a lot of IO wait in glances and the system is sluggish even
though CPU and memory usage is relatively low.
Ideas?
Thanks,
Richard

Calibre on Fedora 33
by Clifford Snow
I'm wanting to run Calibre with DeDRM. Version 5 of Calibre was written for
Python3 while version 4 was written in Python2. DeDRM is only available for
Python2. Python3 support is being worked on but is still in development.
Has anyone found a good workaround until DeDRM for Python3 is available?
Happy New Year,
Clifford

Is it possible to create an email-only user in fedora linux?
by Bill Oliver
So, I am setting up some forum software on a VPS server I have rented
and would like to invite users to have access to the forum *and* an
email account, but nothing else.
I have dovecot set up, and make roundcube available as the web-based
mail client.
The only thing I know to do is to add them as a user, which basically
gives them a shell, and I'm not enthusiastic about that.
The only thing I know about is putting in a bashrc that limits their
PATH to their own /home/<user>/bin file for executables, and then
adding only the executables I want them to have. So, I guess I could
do that, and just put nothing in the /home/<user>/bin file.
Is there a better way to do this?
Thanks,

Android-tools does not find device
by Paul Smith
Dear All,
My Android tablet is stuck on
Fastboot mode.
I have tried to reboot it by pressing POWER and VOLUME UP keys held
simultaneously, but with no success. Consequently, now I am trying to
use
android-tools.
However, when I run the following command, no device is found, in
spite of the fact that the table is connected to my computer running
Fedora by a USB cable:
# adb devices
List of devices attached
#
Any ideas?
Thanks in advance,
Paul

mount source assignment
by Geoffrey Leach
What I have here is the result of two mounts of mp3 players, from
different manufacturers, followed by the (edited) output from findmnt.
What interests me is the source assignment. Any thoughts as to
what might be causing this, or the significance of the change?
% mount UUID=4C2B-B6B0 /mt_test --options rw,user,umask=0000
`-/mt_test /dev/sdb1
..................................^
% mount UUID=1874-44DE /mt_test --options rw,user,umask=0000
`-/mt_test /dev/sdb

xpdf
by Patrick Dupre
Hello,
When I load xpdf (as a standard user), I get:
"/proc/19969/root"
or
"/proc/20111/root"
I can open the file but, I get this message every time now.
What is wrong?
Thanks
