Operations "Cleaning up expired instance snapshots" are piling up

LXD
1

I described my problem in another thread but decided to create a new one since the problem persists.

I have a node in a cluster, in which operations “Cleaning up expired instance snapshots” are piling up until lxd completely exhaust the memory. Here is an example:

Yesterday I had 370 pending cleaning up operations. None of the operations seem to finish. The operations are not cancellable. If I restart snap.lxd.daemon or reboot the machine the operations start and accumulate again. I have restarted about 30 minutes ago and currently I have 44 operations again. Here is the current output of top:

The lxd process has currently 82 threads.

The node has 17 containers and 3 VMs. All except 1 container are stopped. 4 containers have automated daily snapshots (currently keeping between 22 and 76 snapshots). The running container has 76 snapshots and I cannot stop it (because of the piling up operations).

For this container, I can see some old daily snapshots, which for some reason were not automatically deleted. Perhaps they are causing problems:

Here is storage info on this machine:

lxc storage info local --target server1
info:
  description: ""
  driver: btrfs
  name: local
  space used: 2.45TB
  total space: 5.98TB

Any idea how can I stop this madness?

Right, so your system is misbehaving, it looks like those subvolume deletes are stuck in the kernel.

7

Yes, as far as I understand (from what I have read), the subvolume delete operations are blocked by btrfs-cleaner. I am just surprized that lxd keeps creating new threads which then consume all memory and bring the system to a halt. It would probably make sense to set a limit to a number of tasks/threads that can run in parallel.

I have now stopped lxd and am letting btrfs-cleaner to run until it is finished.

Yes does sound like we should limit the amount of concurrent tasks running to avoid making the issue worse.

Please can you log an issue about it over at https://github.com/lxc/lxd/issues

Thanks
