RE: BTRFS hangs - possibly NFS related?

It's been a while, I'm afraid other things took over, but I've finally got back to it.
Definitely repeatable problem , and possibly not NFS

Symptoms - when under significant disk load (this was re-muxing a load of video) anything trying to access the btrfs array locks up (local processes and via samba). Other processes run, but anything accessing the disk stops. Previously the heavy access was over NFS. This is now from a local process (actually a VM, but running locally) - that may take one thing out of the list.

A "sync" will fix it immediately - everything springs back to life, otherwise it runs until the 120s timeout.

System as before - but now 5 disks, RAID1 for data and metadata. I think the question of fragmentation is sorted - the VM images are now in NOCOW files and a daily check of fragmentation shows them in the tens to hundreds of fragments and not growing.

I did manage to catch it in the act and did the standard:
echo 1 > /proc/sys/kernel/sysrq
echo w > /proc/sysrq-trigger
dmesg

Result below.

I'm currently keeping it going with the band-aid of putting a " btrfs filesystem sync" in the crontab at 1 minute intervals. Works apparently fine, but not ideal...!

Any ideas of what I can do to help debug it...?

Cheers
Kim

First off I have absolutely zero experience with NFS or SMB, so if it has anything at all to do with that, I'd be clueless. That said, I do know a few other things to look at, and some idea of how to look at them. The below is what I'd be looking at were it me.

First thing, high load, but little CPU and little I/O. That's very strange, but there's a few things besides that to check to see if you can run down where all that load is going.

With the right tools CPU/load can be categorized into several areas, low- priority/niced, normal, kernel, IRQ, soft-IRQ, IO-wait, steal, guest, altho steal and guest are VM related (steal is CPU taken by the hypervisor or another guest if measured from within a guest, and thus not available to it, quest is of course guests, when measured from the hypervisor) and will be zero if you're not running them, and irq and soft-irq won't show much either in the normal case. And of course niced doesn't show either unless you're running something niced.

What I'm wondering here is if it's all going to IO-wait as I suspect...
or something else.

If you don't have a tool that shows all that, one available tool that does is htop. It's a "better" top, ncurses/semi-gui-based so run it in a terminal window or text-login VT.

Of course you can see which threads are using all that CPU-time "load"
that isn't, while you're at it.

Also check out iotop, to see what processes are actually doing IO and the total IO speed. Both these tools have manpages...

What could be interesting is what happens when you do that sync. Does a thread or several threads spring to life momentarily (say in iotop) and then idle again, or... ?

OK, so you're not full allocation. No problem there.

That looks healthy.

If you've been following the list, I'm surprised you didn't mention whether you're doing snapshotting at all. I'll assume that means no, or only very light/manual snapshotting (as I have here).

My guess is that it might be fragmentation of something other than the VMs. You're not mounting with autodefrag, I take it? What about compress? Do you have any other large actively written files, perhaps databases or pre-allocated-file torrent downloading going on? How big are they if so, and what does filefrag say about them? (Note that the reason I mentioned the compress option is that filefrag doesn't understand btrfs compression and counts it as fragmentation, so any files over ~128 MiB that btrfs compresses will appear fragmented. Also, btrfs data chunks are 1 GiB in size so anything over a gig will likely show a few fragments due simply to data chunk breaks.)

For autodefrag, note that if you try it on a btrfs that has been used some time without it and thus has some fragmentation, you'll likely see lower performance until it catches up. One way around that is a recursive defrag of everything, so when you turn on autodefrag it only has to maintain, not catch up.

And for the VM images (and databases and pre-allocated torrent downloads), you can try setting NOCOW (tho if you're doing automated snapshots it may not help /that/ much). I'll assume you've seen some of the discussion of that and know why/how to set it on the directory before putting the files in it so they inherit the attribute, so I don't have to explain that.

Tho the one thing that puzzles me is that sync behavior; nobody else has reported anything like that that I'm aware of, so I'd guess it either didn't occur to anyone else to try that, or possibly, whatever it is you're seeing isn't reported that often, and you may actually be the first to report it.

One other thing I've seen the devs mention: When you see this happening and the blocked tasks, try:

echo w > /proc/sysrq-trigger

(or simply use the alt-srq-w combo if you're on x86 and have it available, there's more about magic-srq in the kernel's Documentation/ sysrq.txt file). Assuming the appropriate srq functionality is built into your kernel and enabled, that should dump blocked tasks to the console. That can be very useful to the devs looking into your problem.

Anyway, those are kind of broad shots in the dark in the hope they make contact with something worth reporting. Hopefully they do turn up something...
