need help for flashing drive light

[Jim]

The drive light flashes constantly.
Do the following journal lines identify the problem? Or is it something separate, such as a hard drive going bad?

If it is IPV6 related, I have tried all the ways I know to shut off IPV6. Is there a list of things
to be done?

Sep 19 12:50:45 NetworkManager[4151]: <warn> [1726764645.5646] platform-linux: do-add-ip6-address[2: fe80::728b:cdff:feac:1da8]: failure 95 (Operation not supported)

You show Network Manager. Which DE? If Plasma, bring up system
settings/connections. Each configured connection will have a separate
tab for ipv6. Click on that, and under "Method" choose "Disabled." That
should do it. It does for my vpn. (The vpn provider doesn't support ipv6
except through their app - yet. And of course, the app is written for
.deb systems only.)

Other DEs should have something similar for setting things.

It's most likely one of the indexing programs such as akonadi/baloo. I always
disable it on my systems.

$ tail -n 1 ~/.config/akonadi/akonadiserverrc
StartServer=false
$ head -n 2 ~/.config/baloofilerc
[Basic Settings]
Indexing-Enabled=false

Disable akonai and balloo, and reboot.

Disabling ipv6 should only be done if your isp does not support it, which should
be very rare. I found out mine had enabled it, but I couldn't get it to work until
I replaced my router, even though the old one claimed to support it.

If you do need to disable ipv6, reboot after creating a file ...
# cat /etc/sysctl.d/10-disable-ipv6.conf
net.ipv6.conf.all.disable_ipv6 = 1

I think I have tracked the problem, or at least part of it, to avahi-daemon.
the file avahi-daemon.conf contained a line useipv6=yes under [server], and
as mentioned previously I have disabled ipv6. I suspect that resulted in
repeated failure to try to set or do something. The line now is useipv6=no,
and things seem to be working ok.

My desktop is Gnome. akonadi and baloo have been removed from the system.

I disabled ipv6 years ago, because I was not prepared to reconfigure the
firewall to include it, and I did not think I needed it. Thinking back,
I think verizon fios at the time did not support it, but I am uncertain
on that.

Is there any reason I really need ipv6? Services and websites I
use all seem to work, and it just adds one more opportunity
for hacking and cracking via the net.

# cat /etc/sysctl.d/10-disable-ipv6.conf
net.ipv6.conf.all.disable_ipv6 = 1

Do I really need the above? If so, where should I put it? My
sysctl.d contains:

ls -l /etc/sysctl.d
-rw-r--r-- 1 root root 307 May 12 2021 51-alt-sysrq.conf
-rw-r--r-- 1 root root 235 Dec 24 2023 51-drakx.conf
-rw-r--r-- 1 root root 304 Mar 8 2022 tales.conf

https://www.networkacademy.io/ccna/ipv6/ipv4-vs-ipv6 has a discussion on
it. Most of the information is WAY over my head, but you are better
versed in that area.

One advantage is supposed to be increased speed, but I don't notice a
difference, as yet. That could be because I still have memories of the
s l o w speed with my original "Fixed Wireless" ISP, and even worse, my
dial-up days.

Increased speed would be significant for sending huge files. IPV4
is limited to 64K packets but IPV6 can send truly huge packets.

There is a tiny increased speed for IPV6 due to few header fields.

I see no good reason to go through the process needed to add IPV6
to IPV4.
