Comment # 114 on bug 1017461 from Oliver Schmidt

I still see this issue every Monday when the btrfs balance timer kicks in on my
Tumbleweed installation:

first the btrfs balance (both -musage and -dusage) needs 100% CPU on one core
for several minutes, each directly followed by a btrfs transaction also taking
100% CPU. But what's really locking up the system is the heavy I/O apparently.

As it's a 2-weeks old default installation I have snapper and quotas enabled
and haven't yet tried to disable the quotas.

Anything I shall try or logs I shall provide?
I also still have plenty of space left, so it shouldn't be related to the usual
"disk full" problems.

REOPEN this bug or create a separate one?
