Btfrs-transaction issue

Issues & Assistance

Hello :slight_smile:

I am very happy with Garuda Linux, but, I have one Issue with BTFRS. If the task BTFRS-transaction starts, the PC freeze. It is installed on a SATA SSD and I have set Balance, Scrub and Defrag to, weekly, weekly, monthly.

How can I configure BTFRS, that the Transaction is only weekly or something like that. Or better, it doesn’t freeze at all. Today, after the BTFRS transaction after start (Is 20–30 minutes) Where I can’t use the PC, I have it three times after that, that BTFRS-Transaction freeze my PC. I can see it on the Info at my Cinnemon environment. It could be BTFRS-Cleaner with the freeze, too.

Is that anything I could do?

Thanks for the Answer.

Test the LTS kernel to see if the issue persists.

sudo pacman -S linux-lts linux-lts-headers

Choose the LTS kernel from the advanced boot options in the Grub menu at startup, before you log in.

The first test was good. BTFRS-Transaction was only 2-4 minutes and no freeze. So I test it the next couple days.

Thank you for now.

4

Btfrs-Transaction come today after 7h. And it freezes the PC again. Especially Streams. Other things feel like random if the freeze come or not. But it was only 3-4 minutes.

What can I check now too?

5

Yeah I can confirm 4 times today. But only 2-3 Minutes. Twitch stream lags. The reload of this forum lags. Youtube not lag.

It is possible that it collides with snapper.
Do you have timeline snapshots enabled? If so, try disabling that.

Check dmesg for btrfs entries after a freeze.

And fix this:

That was after the freeze. And yes I have Snapper enabled. But the last snap is from 16:00 The freeze was at 16:45 around.

Thank you for your post to my old HDD. I will check this.

Is the BTRFS entrie that what you expect? I Reduce the Snap to 1 Daily. That could be than fix the Problem. Snapshots are useful in case of failure too. What is with the systemd Unit Settings. Snapper timeline enabled, Snapper cleanup enabled, Snapper boot enabled. This also disabling?

8

Nope, that’s not an error, timeout or anything like that.

The snapper thing is just a suspicion.
Try setting everything to the default values ​​in the Garuda BTRFS Assistant and see if that helps:

Subvolumes:
Include Timeshift and Snapper Snapshots → disabled

Snapper Settings:
Enable timeline snapshots → disabled
systemd unit Settings → only enable “Snapper cleanup enabled”

BTRFS maintenance:
Balance/Scrub/Defrag → weekly + all 3 mountpoints activated (Select All)

Ok I try this. BTRFS was on weekly the whole time. I disable timeline snapshots.

Then we will see :smiley: Thanks for your assistance.

Ok. I think, it is the Snapper.

14h no lag. Then I have make manual Snapshot with snapper. After. 10-20 min, the btrfs-transaction and btrfs-cleaner work and it freeze.

Can I set other Settings for Snapshots?

11

Do you have btrfs quotas enabled? If so, try disabling that.

What happens during freeze, high CPU usage or heavy disk i/o?

I have disabled the btrfs quota. I tested the function with 2 snapshots. No Lag. So, that could be the Problem I think. I have read in the archlinux wiki this

Warning: Qgroup is not stable yet and combining quota with (too many) snapshots of subvolumes can cause performance problems, for example when deleting snapshots. Plus there are several more known issues.

So I tested to delete one Snapshot with disabled Quota. No Problem. So, I could test next, to have less snapshots. At the Moment I have 29.

And disk i/o and CPU usage is not very much.

Please do not post here in the forum, like in chat forums like Telegram.

As long as no one has responded to your post, you can edit your post.

With the BTFRS Quota disabled on the LTS Kernel I have no problems. But I cannot boot in the zen kernal anymore. It “freeze” in the boot screen. LTS Kernel runs without Problems.

You should open a new topic for this.

But first take a look here:
