I haven't been able to easily reproduce these in a test environment; however, they have been happening several times a year on servers in production.
Kernel: most recent observation on 4.14.105 + cherry-picked deadlock
and misc hang fixes:
btrfs: wakeup cleaner thread when adding delayed iput
Btrfs: fix deadlock when allocating tree block during leaf/node split
Btrfs: use nofs context when initializing security xattrs to avoid
deadlock
Btrfs: fix deadlock with memory reclaim during scrub
Btrfs: fix deadlock between clone/dedupe and rename
Also observed on 4.20.13, and 4.14.0..4.14.105 (4.14.106 is currently
running, but hasn't locked up yet).
Filesystem mount flags: compress=zstd,ssd,flushoncommit,space_cache=v2.
Configuration is either -draid1/-mraid1 or -dsingle/-mraid1. I've
also reproduced a lockup without flushoncommit.
The machines that are locking up all run the same workload:
rsync receiving data continuously (gigabytes aren't enough,
I can barely reproduce this once a month with 2TB of rsync
traffic from 10 simulated clients)
bees doing continuous dedupe
snapshots daily and after each rsync
snapshot deletes as required to maintain free space
scrubs twice monthly plus after each crash
watchdog does a 'mkdir foo; rmdir foo' every few seconds.
If this takes longer than 50 minutes, collect a stack trace;
longer than 60 minutes, reboot the machine.
Observations:
In the past I've hit the known deadlocks between rsync
(rename) and dedupe, and between snapshot delete and scrub.
These deadlocks aren't those, and current kernels can still
deadlock with fixes for those (and some others) applied.
Deadlocks can occur when there are no snapshot deletes active
and scrub is not running. In a few cases there's been a snapshot
create active during a deadlock event.
The deadlocks occur in bursts, which correlate to periods
of rapid data expansion on the filesystem. e.g. after a big
snapshot delete frees a TB or two of space, there are several
lockups a few days (or even hours) apart. When the filesystem
gets near the free space threshold and a series of smaller
snapshot deletes occur, so that allocated space stays relatively
stable, then there can be months between lockups.
Other bugs in 4.14 kernels break lockdep soon after boot, so
there's only lockdep information in a few cases by the time the
btrfs deadlock happens.
There seem to be a few different identifiable behaviors, e.g.
in some cases the 50-minute timer expires (so a stack trace is
collected) but the 60-minute timer doesn't expire (so the machine
got itself out of the lockup somehow, and doesn't reboot).
Distractions:
In some cases increasing vm.dirty_ratio will unfreeze the
filesystem, in other cases it does nothing. Decreasing
vm.dirty_ratio (e.g. to 2) locks up the filesystem almost
immediately, but it can recover if vm.dirty_ratio is increased
again. I'm not sure if this is because there are two separate
bugs, or just a single bug with corner cases.
Here's a recent lockup example with lockdep output, from 4.14.105 with
the cherry-picked patches above:
