Comment # 72 on bug 1063638 from Aaron Williams

I run into this problem frequently on my laptop running Tumbleweed. Now I have
not done anything to change qgroups or quotas, though I did change how often
the rebalancing occurs to monthly instead of weekly.

Now I don't boot my laptop all the time and it might go weeks without use. It
has a 100GB btrfs root filesystem. When the rebalancing occurs, it's guaranteed
to go out to lunch for quite some time.

A couple of months ago I had to shut down my laptop by holding the power button
down. Afterwards, it could not mount the root filesystem until I ran the fsck
tool which spewed a lot of errors and took around 20 hours.

Just the other day I booted up my laptop and it started its rebalancing
procedure, again rendering it unusable. In this case, I did not have the
charger handy and I again was forced to shut it down with init 0. It eventually
did so. After I found the charger it would only boot into single user mode
until the rebalancing completed after quite a bit of time.

I installed Tumbleweed a year or two back and have continually updated it since
then. It also has a 1TB SSD drive.

I can't say I've had any experience with BTRFS with leap because a few years
ago I tried BTRFS and it left a very bad taste in my mouth. The performance was
abysmally slow and I switched to XFS. I generally always choose XFS instead of
BTRFS due to its stability, performance and tools.

I must say I am looking forward to when the next generation XFS comes out.

If you want a system that acts up, my laptop does so frequently.

Note that my laptop has also hung in the past numerous times requiring holding
down the power button in the past, but now it seems stable as long as BTRFS
behaves.
