I confirm the same issue here on my Tumbleweed on a Lenovo Yoga 520 a few minutes ago. My pc is a 6th gen i7 and it remained freezed for +30min and only stop after I applied the workaround below. The workaround that seems to have worked was to disable quota on the system folder "/" with the command "btrfs quota disable /" . Let's see if the system remain stable. In fact, it seems to be a known serious issue on btrfs fyle systems and there are some good problem reporting on this if you google it. I also would like to know more information from experts on what are the implications of disabling quota in openSUSE (Tumbleweed/Leap) or related distros? The information I found on the web was very dubious on that matter. -- You are receiving this mail because: You are on the CC list for the bug.

But my computer is not a slow computer. It is a brand new Dell Presicion 5820 with 32 GB RAM and 7 processors Intel(R) Xeon(R) W-2123 CPU @ 3.60GHz. I decided to not split /home on my machine, so the whole system is on a 500GB btrfs SSD (Micron 1300 SATA). The freeze is not absolute. I am still able to make simple things. But for example "exec su -" takes nearly one minute to display prompt. I need to wait tens of minutes to be able to work normally again. During the freeze, two processes show 100% load: btrfs-cleaner btrfs-transacti -- You are receiving this mail because: You are on the CC list for the bug.

System was not absolutely frozen but even ssh login took a 30 sec before succeeded. Executing anything from shell was taking a long delay before able to run. The "top" command reveled 100% CPU utilization on btrfs-cleaner kernel thread. I was able eventually run "btrfs quota disable /" and system started to be responsive again after a while. It was in the middle of the day and as a database server running MariaDB and PostgreSQL it is not acceptable for the server to stop responding and do some btfrs cleanup even for few seconds nor 15 minutes IMHO. Server: Leap15.2 up to date, 32GB RAM, SSD 512GB, 2x8core XEON, FS 20% full We are using timeline and number snapshots on /backups subvolume and number snapshost (created by zypper) on / Is there any way I can help to resolve this issue? -- You are receiving this mail because: You are on the CC list for the bug.

you can disable snapshots on installation. Also you can disable all services that you think are problematic as well as disable btrfs qgroups. -- You are receiving this mail because: You are on the CC list for the bug.

thanks I am not a techie person. How to disable snapshots after installation ? How to disable qgroups ? What is the consequence of disabling qgroups ? There is only one service which starts at PC startup "btrfsmaintenance-refresh". I assume it is a bad idea to disable this service. No ? -- You are receiving this mail because: You are on the CC list for the bug.

How to disable snapshots after installation ?
I don't know.
How to disable qgroups ?
Sorry, I don't know either.
What is the consequence of disabling qgroups ?
Not sure, likely no space-aware snapshot cleanup.

Yes, this is why it's there by default :) -- You are receiving this mail because: You are on the CC list for the bug.
