Btrfs system remount ro sometimes

fperal · April 1, 2025, 4:44pm

Opensuse 15.6 Plasma.
I have a btrfs system on a m.2
I usually don’t swithc off my computer unles I have updates that require restarting, I have it set to suspend to RAM whan I’n not using it in 10 minutes (I have measure consuption and is more or less the same that when poweroff about 5W).
Some weeks ago my system went ro, I don’t know why. I powered of the pc, started again and everything worked fine. The same issue is happening sometimes, and the lap between times is getting smaller (now more or less once a day or two).
I have done some test

Well there are errors in the btrfs filesystem.
But I don’t know if they may be causes by any powerloss I have had (I don’t remember but maybe I had one) or because of faulty hardware.

What should I do?

best regards

arvidjaar · April 1, 2025, 5:30pm

Boot any live image with recent btrfsprogs version (e.g. Tumbleweed), run

btrfs check /dev/nvme0n1p1

and provide full output. Do not mount the device when doing it.

fperal · April 1, 2025, 9:56pm

OMG tons of errors

file

arvidjaar · April 2, 2025, 4:22am

Well, you have two options

Backup whatever data you want to preserve and reinstall. This is the easiest and fastest way.
Ask on the btrfs mailing list whether there are chances btrfs check can correct these errors.

Of course, after having backed up you may simply try btrfs check --repair if you are truly adventurous.

And yes, it may be caused by power outage. But that would imply bad behaving disk which lies about committing data to the stable storage.

fperal · April 2, 2025, 7:18am

ok thanks, I’m doing a dd copy of the full disk and then I will try … maybe the two options.
I think I will use ext4 for the new installation. This is the 4th computer I have had issues with btrfs and the conclusion is always the same: no way (or at least easy or secure way) to recover. I have been using ext4 for years on several coputers and I don’t remember something like this happening.

knurpht · April 2, 2025, 8:42am

Use the defaults , ie btrfs, u won’t regret it

malcolmlewis · April 2, 2025, 3:05pm

Likewise multiple systems with btrfs running some for many years on SD cards even through upgrades and no issues. I do also have ext4 systems

fperal · April 3, 2025, 6:39am

But why?
That’s what I thought when I moved my system from a HD to a M.2, installing a new system and moving my /home. Previously it was ext4, no problem ever. … and now I’m regreting.
If a problem like this had happend on ext4 a fsck would have fixed the errors, but with btrfs you can’t do a fsck… What’s the point in using a fs which in case of errors you have to reinstall?

malcolmlewis · April 3, 2025, 11:21am

@fperal So why are you getting errors? Sub standard or failing hardware?

fperal · April 3, 2025, 9:55pm

I don’t know.
I guess the line
Error Information Log Entries: 4,896
in smart info is not awsome

malcolmlewis · April 3, 2025, 10:19pm

@fperal I meant anything proceeding the failure, power failure etc. How old is the storage device, what does smartctl say about the device etc?

fperal · April 3, 2025, 10:33pm

The device is more or less 2 years old
There has been at least a power loss for sure
smartctl info is this

btrfs as configured by openSUSE is as rock solid as can be. But hardware matters. From Hardware as the main source of filesystem corruptions:

“If you use unreliable hardware and don’t know about that, don’t blame the filesystem when it tells you.”

I always check a drive for reliability and atomicity by:

Write random data to the btrfs (80% usage)
Run btrfs scrub.
Run full btrfs balancewithout filters.
Press the restart button or power switch during balance and restart.

If any of the above fails don’t add the drive to btrfs.

fperal · April 5, 2025, 11:47am

I have been asking in the irc channel and in the btrfs mail list. The conclusion, the errors where not recoverable so it brings me to reinstall the fs.
The cause of this is not clear maybe some issues with the disk, maybe a bug in some piece of software in the kernel … that is maybe a one-time error (although it is not for sure).
But… the number of files affected where not much and where not critical at all… in fact I can recover the fs but copying to a new one.
What I have done:
first, as I said I made a copy of my full disk to a sata spare disk

dd if=/dev/nvme0n1 of=/dev/sdd  bs=4M

The copy went without any error

Then and just in case, I made another copy of /home
I booted from a live cd, mounted the / and /home

mount /dev/nvme0n1p1 /mnt
mount -o subvol=@/home /dev/nvme0n1p1 /mnt/home

and then did the tgz

tar -czf home_backup.tgz /mnt/home

also without any error

Then I changed the M.2 for a new one just in case (I took advantage of the situation and went from 1TB to 2TB nvme)

I created a GPT table with 4 partitions
1- / (ext4)
2- /home (ext4)
3- efi
4- swap

With the last tumbleweed cd in rescue I mounted

mount /dev/nvme0n1p1 /mnt
mount /dev/nvme0n1p2 /mnt/home

Then I create /backup and mounted the sata disk with the dd copy of my “old” nvme with all subvols excepts .snapshots

mount /dev/sdd1 /backup
mount -o subvol=@/var /dev/sdd1 /backup/var
mount -o subvol=@/usr/local /dev/sdd1 /backup/usr/local
mount -o subvol=@/tmp /dev/sdd1 /backup/tmp
mount -o subvol=@/srv /dev/sdd1 /backup/srv
mount -o subvol=@/opt /dev/sdd1 /backup/opt
mount -o subvol=@/root /dev/sdd1 /backup/root

And then I made a full copy with rsync

rsync -aAX /backup/ /mnt/

The rsync reported some errors

Some considerations about the errors

They were all in /var and /opt subvolumes I’m not sure if it means something
There were few errors … at least for what I was expecting for the size of the file created for the btrfs check command.
None of them was important.

So I edited /mnt/etc/fstab, changed the mounts from the btrfs ones to the new 2 ext4 partitions, create a mount of the new efi partition (I was not using uefi) and recreate the boot (and initrd as I got a error when first try to boot the system because the kernel didn’t knew ext4)

And now: why have I changed to ext4?

I have been reading a lot about btrfs this last couple days, it seems awsome, yes, it has a lot of features ext4 does not have… but if i don’t use snapshots, nor compression, nor raid nor encryption I don’t see the advantage in using btrfs.

Reading the doc, the most awsome point of btrfs to me will be “Self-healing - checksums for data and metadata, automatic detection of silent data corruptions”
But yes, checksum is awsome form data corruption detection, but not for healing, Correct me if I’m worng but the healing capacities of btrfs need redundanci to be used, so it is necessary to use raid for it. I you don’t use RAID yo have no healing.Yes, you still have a very good mechanism to detect corruption (CRC).
But what I lack is a tool to repair the filesystem if there is corruption, some tool that, in my case will let me say “remove this faulty files” and set the filesystem to a OK state.
I think this can be done with “normal” fsck in ext4 or in ntfs for instance, right?

A storage meltdown wiped the vfat and damaged the btrfs:

erlangen:~ # lsb /dev/nvme1n1
PATH           LABEL  UUID                                 FSTYPE MOUNTPOINT
/dev/nvme1n1                                                      
/dev/nvme1n1p1 EFI-S  6BDF-0391                            vfat   /boot/efi
/dev/nvme1n1p2 System 0e58bbe5-eff7-4884-bb5d-a0aac3d8a344 btrfs  /var
erlangen:~ #

Data on vfat were lost, data on btrfs were recovered: 1228937 – btrfs balance kernel BUG at fs/btrfs/backref.c:3206! All damaged files were generated ones. Thus no data loss occurred.

After recovering the system I have had a crash of the computer.
I was originated when opening a firefox window (having already other ff windows opened)

After a reboot I extract the info from the system log:

It seems to be caused by a page fault in the kernel which it can’t manage.

Some things I can see:

Unloaded tainted modules: it87(n)
It is breaking at anon_vma_interval_tree_iter_first

Can I extract some more info or try something to see it I fix the error?

What was the reason for module unloading? It is in general not supported and considered more a debug feature.

You should really open bug report. And if you do it, provide full logs, not with truncated lines (never copy-paste logs from a pager program, always disable pager if you are using journalctl).

[quote=“arvidjaar, post:17, topic:183971, full:true”]

I don’t know. I don’t even know what it is.
Searching in the logs I only find this

and this

This last one suggest it is not a temperature sensor as I previously thought but a watchdog module: it87_wdt

Sorry, full output
