Hi guys!

Yes, this is a **very** serious problem. I have already reported that my
system is unresponsive every time btrfs maintenance starts, and I am using
Tumbleweed. I posted to the mailing list, but received just one answer:

Indeed, when I **disabled** quotas here, then the freeze stopped. Thanks for
that workaround! Actually, a btrfs developer (Chris Murphy) has already
warned that the quota feature is not stable in btrfs and must not be used by
default on production systems:

However, some openSUSE developers contradicted Chris, specially Richard

Hence, nobody took the advice and quotas were enabled by default in Leap

Maybe now with this bug, which I can confirm that is happening in **all** my
machines with quotas enabled (HP Workstation, Dell laptop, and a Macbook),
this problem can be revisited. Furthermore, disabling quota fixes it also in
all my machines.

Hmmm, I fear quotas are enabled because of snapper(8). It seems to use them
for some clean-up policies.

You are receiving this mail because:
You are on the CC list for the bug.
