Problems with disk? apps failed, then reboot failed. Needed fsck
by Robert Moskowitz
I was working away this morning and got a failure with LIbreOffice. Was
not actually using it, but then the dialog popped up without the content
being filled out, Just whatever was on the screen when it opened...
I could not get OpenOffice to restart. It did create a abrt and tried
to upload a bug report, but that failed.
I tried to open my Fedora mail folder to see if anything was being
discussed, but Thuderbird would not show content of the folder.
Oh, oh time. Time to reboot. But first do a 'dnf update' and got a new
LibreOffice.
Reboot failed. Got dropped in emergency mode. Turned out my /home
partition was not mounted.
I have not had to deal with this in YEARS and I am away from home so no
old system to fall back on. In fact no other computers here. Internet
via my cellphone.
I remembered the disk recovery program started with 'f', fortunately not
too many such and found fsck which I ran on /dev/sda5
Lots of errors I let it fix and as you many guess I am now up and running.
LibreOffice recovered the docs I had open.
Thunderbird is opening folders.
I guess other things are working,
but 2 items.
LibreOffice uploaded a dump, but I did not create a bug report. Should I
(I did get a new LibreOffice in all this). If so, how do I find what
was uploaded to link to a bug report?
How do I figure out what fsck fixed and what may now be a broken
important file? It could just be tmp junk for all I know.
Anyway big scare here with only a non-working computer and no one to
talk to for help, as I have not been in this sort of recovery mode for
years. I was not looking forward to getting home tonight and THEN start
recoverying.
Backup first order of business tomorrow morning.

F35 problems with Xfce Application Finder
by Robert Moskowitz
F35 with Xfce:
<Alt-F2> brings up the Application finder.
I type in, say, VNC, to get to TigerVNC.
I see /usr/bin/vncviewer as the option?
I press enter, and I get a instance of Thunar open to /usr/bin.
Other programs do the same thing, some work (like Firefox).
How to I correct this?
thanks

The definitive guide to replacing a disk in raid1?
by cen
I recently had to replace a bad disk in raid1 array and finding proper
docs was not a good experience.
There is apparently also a trap with not having a bootloader installed
on the replacement disk which can make the system unbootable in cause of
array degradation. Some of the guides don't mention this, I just
happened to stumble upon this information on serverfault.
I came up with these steps, can someone verify this is the correct way
with no hidden troubles lurking somewhere?
/dev/sde - remaining healthy disk
/dev/sdf - bad disk
/dev/sdd - new disk
# remove bad disk
mdadm --fail /dev/md127 /dev/sdf1
mdadm --remove /dev/md127 /dev/sdf1
# copy partition map from good disk to new disk
sfdisk -d /dev/sde | sfdisk /dev/sdd
# verify the new disk has boot, raid flags and /dev/sdd1 is same size as
/dev/sde1
parted /dev/sdd print
# remove raid metadata
mdadm --zero-superblock /dev/sdd1
# install bootloader on new disk
grub2-install /dev/sdd1
# add to the mirror
mdadm --grow /dev/md127 --add /dev/sdd1 --raid-devices=2
# watch it rebuild
watch -n 5 -d cat /proc/mdstat

OT: Linux kernel version in fiber modem
by Jonathan Ryshpan
On a whim I opened up the:
Legal Disclaimer Open Source Licenses
in the management page for my fiber modem (ATT installed 2021/03/30)
and discovered that the kernel is rather old:
linux kernel - Version 3.4.11
There are about 163 other open source components, probably most of
similar ages.
Is this a security problem?

Setting up bitcoin for purchases
by Alex
Hi, I'd like to set up bitcoin to pay for services online. Do you have
a guide you can recommend on how to do this for fedora35?
My search shows this one from about five years ago. Is this still current?
https://fedoramagazine.org/bitcoin-fedora-electrum/
I'd like to link it to a credit card or a specific physical bank
account to use it to pay for random things and to just play around.
Thanks,
Alex

Panel Problem
by Joe Zeff
I'm using Fedora 31, Xfce 4.14 and Compiz and am not in a position to
upgrade right now. My preference is to have one panel, at the bottom of
the screen, but suddenly that panel moved up until the bottom was where
the top should be. Restarting Compiz didn't help, nor did logging out
and back in without saving the configuration. Trying to go back to an
earlier setting just gave me a full top panel and a short bottom one.
I've managed to remove the bottom one but I can't find out how to get
that remaining panel back where it belongs. Does anybody know what
happened or how to correct it? And yes, the panel is unlocked.

condor
by Patrick Dupre
Hello,
I am trying to run condor to subgmit jobs in batch
I first run
systemctl start condor.service
but I get
SElinux security alert
SELinux is preventing condor_master from getattr access on the filesystem /sys/fs/cgroup.
***** Plugin catchall (100. confidence) suggests **************************
If you believe that condor_master should be allowed getattr access on the cgroup filesystem by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'condor_master' --raw | audit2allow -M my-condormaster
# semodule -X 300 -i my-condormaster.pp
