System randomly got stuck in read only, can't do anything or open most applications such as discord to send screenshot.

-mkdir test
mkdir: cannot create directory 'test':read- only file system

btrfs corruption- idk how

ruby dagger Jan 17, 2026, 8:55 PM

#

yeah that should not exist right? it literally formats the device before installing

ruby dagger yeah that should not exist right? it literally formats the device before install...

correct, so either your ssd is corrupted, or you installed an older version or you did an abnormal manual install

sorry, app didn't scroll down when i clicked in

ruby dagger Jan 17, 2026, 8:56 PM

#

i installed the one right before 3.30? i think

#

i installed the latest one when i installed omarchy

#

which wasl ike

#

uhh 3 weeks ago or something

polar patrol Jan 17, 2026, 8:57 PM

#

ruby dagger i installed the one right before 3.30? i think

3.3.2 is latest avail afaik.

i'd strongly recommend that one, reflash a usb for that iso and reinstall

ruby dagger Jan 17, 2026, 8:57 PM

#

i kept updating each update

#

also would you know how do i check if it's my ssd?

#

i actually can't open shit

#

so i can't google the commands

lost gazelle Jan 17, 2026, 8:59 PM

#

dmesg | grep -i ata

#

those journald entries are noisy

polar patrol Jan 17, 2026, 8:59 PM

#

ruby dagger also would you know how do i check if it's my ssd?

it's your box, if you can't open it idk what to tell you

that's a choice you have to make on where to spend your time based on your life

lost gazelle Jan 17, 2026, 9:01 PM

#

well if you need your laptop and works for what you need during the exam... then put it off

#

ro isn't going to hurt it

ruby dagger Jan 17, 2026, 9:02 PM

i can always study on my phone but that'd be a pain in the ass

lost gazelle dmesg | grep -i ata

#

could not unmount properly

#

interesting

polar patrol Jan 17, 2026, 9:03 PM

#

lol dawg fixing problems is a pain in the ass- you just have to decide what's worth your time and move forward with that

Might try the Checking Status and Scrub sections. Don't mess with rest of the page since you don't know what the underlying issue is yet.
https://blog.programster.org/btrfs-cheatsheet
typically when the fs remounts to ro, there is a hardware issue e.g. disk, controller, etc...

#

scrub won't be able to fix anything since it's in ro

#

if you decide to wipe and reinstall, after you backup whatever data you want to keep, try 'mount -o remount,rw /' then see if scrub fixes anything.

ruby dagger Jan 17, 2026, 11:00 PM

#

I decided to reinstall

#

And I did scrub

#

So far it's working fine

polar patrol Jan 17, 2026, 11:03 PM

#

plz update this with resolved

ruby dagger Jan 17, 2026, 11:03 PM

#

I am also doing ssd checks doing smartctl

ruby dagger Jan 17, 2026, 11:03 PM

#

polar patrol plz update this with resolved

I don't believe it's resolved yet.

#

I still want to know why this happened

polar patrol Jan 17, 2026, 11:05 PM

#

ruby dagger I don't believe it's resolved yet.

that's fine and all- but the omachy dev team tracks things that need their attention based on the tags.

You made a choice to reinstall and scrub, so your issue isn't there anymore- that's one less thing that they have to run through

#

or keep it here if you think its their job to ffigure it out for you

ruby dagger Jan 17, 2026, 11:05 PM

#

Aren't you a ray of sunshine

polar patrol Jan 17, 2026, 11:07 PM

#

cheers- i'm fine stepping back from folks who don't want my help

ruby dagger Jan 17, 2026, 11:12 PM

#

If you actually tried reading what I said, you'd have known that I was running some tests to see if the problem was my ssd or if it was just the system having issues.

ruby dagger Jan 17, 2026, 11:27 PM

#

@lost gazelle i scrubbed and i am currently trying to do a weekly schedule to scrub automatically

#

would you say there is something else i should try to do? since i really couldn't find a reason as to why the errors were happening in the first place

lost gazelle Jan 18, 2026, 12:14 AM

#

what does smartctl say?

#

smartctl -A /dev/sdX

#

i'm a little fat happy and slow right now. just got back from sushi

ruby dagger Jan 18, 2026, 12:21 AM

#

seems pretty healthy

lost gazelle Jan 18, 2026, 12:21 AM

#

what coomand?

ruby dagger Jan 18, 2026, 12:22 AM

#

sudo smartctl -A -d nvme /dev/nvme0n1

#

i am not using sdX

lost gazelle Jan 18, 2026, 12:22 AM

ahhyou kept saying ssd

ruby dagger Jan 18, 2026, 12:22 AM

#

i am using an ssd

lost gazelle Jan 18, 2026, 12:22 AM

#

nvme

ruby dagger Jan 18, 2026, 12:23 AM

#

would that not be an ssd?

#

i always called it as such lol

lost gazelle Jan 18, 2026, 12:26 AM

#

just a hunch but 'Error Information Log Entries: ' should probably be 0

ruby dagger Jan 18, 2026, 12:27 AM

#

oh yeah that one was weird let me see which one it was

lost gazelle Jan 18, 2026, 12:27 AM

#

ruby dagger Jan 18, 2026, 12:27 AM

#

invalid field in command

#

weird error

lost gazelle Jan 18, 2026, 12:28 AM

#

you cutoff the command. kind of helps to know what you're doing

#

your nvme might be getting ready croak

ruby dagger Jan 18, 2026, 12:31 AM

#

i thought that error was not that serious?

lost gazelle Jan 18, 2026, 12:32 AM

#

here's what a ssd looks like

#

spinner

#

if row 5 has anything that other than 0 in the raw_value column, prepare for disk failure

#

anywho, i would look at replacing your nvme

#

i'm probably wrong, seeing that error doesn't mean a whole lot. interesting.

ruby dagger Jan 18, 2026, 12:38 AM

#

lost gazelle

yeah exactly

#

here again just in case i had a brainfart a while back

#

i don't get it though

#

it acts up like crazy

#

is there any chance there might be another hardware component shitting itself that may cause btrfs issues?

#

also the error "invalid field in command" is not a hardware thing from a quick google search

lone osprey Jan 18, 2026, 12:39 AM

#

invalid field in command nvme

#

how to prevent this from happening hehe

lost gazelle Jan 18, 2026, 12:40 AM

#

could be, maybe memory. most linux install isos have memtest in the grub menu. could fire that up on boot. doesn't touch data

#

if you catch it when it goes into ro, do 'dmesg | tail -50' or 'journalctl -n20 -f' to see the last 20 syslog entries and follow. ctrl+c to get out.

#

might be able to spot it

#

i see your buddy left? lol

ruby dagger Jan 18, 2026, 12:44 AM

#

i vaguely remember this

#

volume was not properly unmounted

lost gazelle Jan 18, 2026, 12:45 AM

#

that could be from power loss

ruby dagger Jan 18, 2026, 12:46 AM

#

lost gazelle that could be from power loss

could be seeing the unsafe shutdowns

lost gazelle Jan 18, 2026, 12:47 AM

#

right

ruby dagger Jan 18, 2026, 12:47 AM

#

how probable is it that btrfs was panicking because of the unsafe shutdowns?

lost gazelle Jan 18, 2026, 12:47 AM

#

shouldn't. i haven't had issues like that with btrfs

#

did you remount and run a scrub?

ruby dagger Jan 18, 2026, 12:49 AM

#

yes i did that after you told me a couple messages back

lost gazelle Jan 18, 2026, 12:50 AM

#

did scrub report any issues?

ruby dagger Jan 18, 2026, 12:50 AM

#

not at all

#

driving me crazy

lost gazelle Jan 18, 2026, 12:50 AM

#

has it gone back to ro after the remount?

ruby dagger Jan 18, 2026, 12:51 AM

#

back then it did remount then went back after

#

but after reinstalling it seems fine for now

lost gazelle Jan 18, 2026, 12:52 AM

#

oh wow, so fresh system?

ruby dagger Jan 18, 2026, 12:52 AM

#

yeah i had to reinstall nothing worked

#

it used to happen before when i had fedora

#

and ubuntu before it

lost gazelle Jan 18, 2026, 12:52 AM

#

well that's a bummer. hopefully you don't see that happen again

ruby dagger Jan 18, 2026, 12:53 AM

#

welp thanks a lot for the help!

lost gazelle Jan 18, 2026, 12:53 AM

#

makes me think you have a hardware issue

#

np, run memtest when you can. might have a bad ram stick

#

btrfs is a cow fs. so copy on write with memory issues can cause problems.

ruby dagger Jan 18, 2026, 12:54 AM

#

yeah i've been doing that as we're speaking

lost gazelle Jan 18, 2026, 12:55 AM

#

haven't seen it with btrfs yet but have with zfs

ruby dagger Jan 18, 2026, 1:02 AM

#

the fact that i've never tested my ram yet

#

is mind boggling

#

so yeah it's failing

#

lost gazelle Jan 18, 2026, 1:06 AM

#

test one stick in at a time until you find the bad one and replace :(

ruby dagger Jan 18, 2026, 1:11 AM

#

Thanks a ton!

lost gazelle Jan 18, 2026, 1:11 AM

#

np, glad to help

#

if it has more than one stick and you figure out which stick, yank it and run with what's left until you get a new one

ruby dagger Jan 18, 2026, 1:14 AM

alright
