Has anyone had problems with BTRFS installs? I have tried it on multiple systems and have had nothing but problems. I tried the Endeavour installer, vanilla Arch a few different ways, and it even caused problems on my Nextcloud/UniFi server running Debian, which was faultless on extra.
My systems would become unresponsive for about 20 seconds at a time randomly. I thought it first it was the kernel, changed to lts and sill acted up. Then I thought it was related to KDE or Arch, but my server started acted up and it uses xfce and Debian. I also noticed that when the server became unresponsive the hard drive activity light was constantly on, like the disk was thrashing when I had a hhd and Windows Vista. All the machine run on SSD’s.
Now my data is corrupt on one of my laptops and my server. I tried to restore my server using timeshift but it tells me there is no snapshots like they were deleted.
I did a fresh extra install on my laptop two days ago and it is running flawlessly.
Works fine here.
In order to help you we would need to get some information from a system that wasn’t working well for you. If you have already replaced them all with ext4 it will be hard to figure out what the issue was.
Welcome to the forum!
I did redo the my main laptop, but I have another and the server is still “up,” well, not wiped completely yet. Corrupted to hell probably.
What do you need from it? I can get it later.
sudo btrfs subvolume list /
findmnt -t btrfs
Plus any relevant errors from journalctl would be a good start.
However if the filesystem is corrupt, it might be too late to get that info.
As a side note, snapshots alone won’t protect you from filesystem corruption because they live inside the filesystem.
I don’t think my laptop is screwed like the server. It is “useable” between the hangs. When it does this the mouse is responsive, but it ranges from a single freezing app to the entire de.
I’ll upload the output in a bit for you. Thanks.

All look fine.
What about specific error messages, or problem on each one.
Please, remember that each system is a unique HW/SW combination, even if they look the same .
Ok, I have quite a bit of experience with Linux, but not so much with troubleshooting. I guess I rely on timeshift way to much! Usually if I have a large problem I just do a restore or start from scratch the Windows troubleshooting way.
I think this might be my problem. I am using Timeshift with qGroups and I guess that is breaking my system:
Yes, it’s Manjaro, but it is what I found that is exactly like my issues. But if it wasn’t for Manjaro being so bad for me I wouldn’t be here!
Yes. Enabling quotas can definitely cause performance issues. I don’t think it is a hard requirement of timeshift though.
That was the problem. It’s fixed now. Thanks.
You’re right, it isn’t really required, BUT …
… you probably introduced a new problem by fixing the IO-slow-downs when disabling btrfs quotas.
There’s an unfixed bug in Timeshift, where Timeshift fails to completely remove snapshots on the first try.
On this first try everything except the snapshot’s “
info.json” file is actually deleted. This causes Timeshift to still list this (now unusable) snapshot! A second remove attempt then successfully removes the already deleted snapshot from the list.
This behaviour seriously messes up scheduling because actually deleted snapshots are still counted.
I posted this bug on timeshift’s GitHub pages quite some time ago (1) (2) but the issue still seems to be open.
There are some workarounds in the provided links -OR- you could just use
snapper if you encounter this behavior.
Yeah, just found this bug and was about to post it before I saw your post. I just stopped using autosnap and just manually do backups every few days or when I do an update, which I do once a week. I think this will work for now. I used snapper in the past but I like Timeshift better since I have always used it since it was introduced into Mint.
Question about disabling quotas. When I use the command “sudo btrfs quota disable /” is it reclusive and disable all quotas or do I have to do it for each subvolume?
