Another crash after Manjaro couldn't stop processes

So Manjaro crashed again…

A lot of processes couldn’t be stopped, i had to force reset it.
Booted great after though. Weird.

Started out with Brave crashing, it just displayed a black void, no window borders, nothing, just black.
And looking-glass couldn’t start.

Here’s a wetransfer of journalctl --no-pager -p 3. I outputted it to a file cause it’s huge, too big for forums and over 512 kb for pastebin…

It’s from last few days of use.

Also, every time i reset it, or shut down, it keeps writing “watchdog did not stop”. It didn’t do that before.

Also, side note - is there a way to delete unnecesary stuff that might be filling my drive space but it’s not really needed? My drive keeps filling up and i’m not really doing much to it, it just has less and less space for some reason, not sure why.

Posting it somewhere and linking to it is a good idea, however:
limit the output to the last boot - or to just one - and perhaps don’t restrict the log level to 3 (and lower), as you did.
Or do separate dumps, one for each log level …
Your command dumps all the logs that you have from the beginning of time, so to say …
use -b 0 or something

not critical and quite easy to address - but not now

There are a lot of coredumps (browser and plasmashell) to see in your log file - they can create huge files
make sure they are not kept - they are pretty useless anyway

and your cd-rom/dvd drive is producing a lot of read errors

Yeah, i need to learn how to use journalctl properly, i’m just copying and pasting the command, not really knowing what i can do with it…

How do i do that?

Huh, didn’t notice that… I’m not really using it, can i somehow disable it, then re-enable it only when i need it?

cat /etc/systemd/coredump.conf
shows you the file content

edit it so that this line:

also to prevent huge log files:
edit /etc/systemd/journald.conf
and change this line:
#Storage= ...
to this:

or to a value that better suits your needs.

man journald.conf

The prudent way to deal with large log files is, of course, to deal with and address the errors that are mentioned in them - instead of just not looking at them.

a lot of entries like this:

sij 20 03:02:37 manjaro-linux kernel: I/O error, dev sr0, sector 1 op 0x0:(READ) flags 0x0 phys_seg 1 prio class 2
sij 20 03:02:37 manjaro-linux kernel: Buffer I/O error on dev sr0, logical block 1, async page read

I assume /dev/sr0 is your cdrom drive

perhaps there is a disk in it?
there has to be a disk in it for read errors to occur

The only way to disable it that I know of is to disconnect it.
… saves power, too

Thanks! I did that.

Yes, that’s the DVD drive but, there’s no disk in it… :confused:

Yeah, if it keeps causing problems, i might just do that…
But i don’t know how it made errors without a disk in it…
