Bug: Apparent infinite loop on deduplication
Hello,
I've been using bees for a while now to dedupe my filesystems. Recently I started switching from release 0.10 to 0.11 on a few select machines of mine. Yesterday I noticed an issue for the first time where bees was constantly running in the background on 100% CPU utilization (i.e. single core, full load).
At first I suspected my CLI arguments might have been faulty:
--verbose=3 --scan-mode=4 --throttle-factor=0.9 --loadavg-target=10.0 --thread-min=1
my previous usage (with version 0.10) was:
--verbose=3 --scan-mode=1
so I stripped everything after scan-mode=4 away but the problem remained. Next I enabled debug logging (--verbose=7) and repeatedly found the following messages in the output:

I restarted bees multiple times but the problem remained. Next I entirely removed the bees working directory including the previous hash table and had it rerun on the filesystem over night, but it ended up in the same weird state.
I tried creating a MWE by creating a blank, file-backed btrfs and copying only the apparent "faulty" files in, but couldn't reproduce the issue there. Right now I'm having it rerun with --scan-mode=1 to see if it's a generic issue, but that may take a few more hours to complete.
I have no idea what's happening there. I checked the files and they're both ~190 MB in size, which I assume shouldn't cause multiple hours of runtime. The backing storage is an NVMe SSD after all. Do you have an idea what may be causing this? Is there something I should try perhaps?
Thanks in advance!
I don't see a loop here:

It's making progress. But it is going over snapshots. Maybe you are seeing my problem https://github.com/Zygo/bees/issues/320?
Especially flatpak data directories have been a problem for me.
#320 is a remarkably thorough explanation of how the implementation works, fascinating. You're right, on closer inspection I can see that the transid in between log messages indeed increases by 1 each. But the progress reports (as seen above) tell me it's all caught up, right? I still don't understand why for all of these transids it's apparently hung up on the same pair of files.
I've let bees "settle" with --scan-mode=1 now and am switching back to --scan-mode=4. I'll keep the verbosity at 7 and report back once it has stopped finding yet more extents to dedupe. Maybe the issue resolves itself now in another over-night run.
The ref tag tells us:
- the extent length is 189M. This tells us that the file was preallocated, because the only way to get an extent longer than 128M in btrfs is due to a kernel bug in preallocate.
- there are 3 total references to the extent, so it's not spinning on a huge number of references.
Other things we can infer:
- it's being considered for dedupe, so there's at least one duplicate block somewhere else.
- it's growing extents up to 128M, so the duplicate copy is fairly large. It could be the extent bees is using to try to dedupe the prealloc portion of this extent.
Prealloc extents are removed upon detection. This is handled before any other deduplication. It will show up in the full debug log when it happens.
Is the file being written in between, or is bees the only active writer touching this file?
Can you post the full debug (-v8) of this loop?

That sounds like you're actively fixing certain known kernel bugs. If that's the case I'm amazed and thank you very much. :-)

Afaict bees is the only writer, anything else should only read these files. Whether they have been read from during the logging period posted above I cannot tell unfortunately.
Can you post the full debug (-v8) of this loop?
I'm afraid right now I can't, yesterday it finished and now bees is politely waiting for more work in the background. It appears I've been too impatient... Sorry for the noise, but thank you for the quick responses!
I'll close the issue because the initial "bug" turned out not to be a bug and the problem has gone away now. If either of you is interested in the full debug logs I can probably delete the bees hashtable and have it run again from scratch. Let me know if that's the case, otherwise: Thank you!
I'm afraid the issue reappeared. This time I remembered to restart bees with -v8 and recorded ~4 hours of log data, see below. The problem still persists, so if you need more data I should be able to provide that. I've stopped bees on this machine for the time being because it's a laptop and I'd like to keep my battery for a little longer...
Hi,
I want to chime in that I'm facing the same issue on both latest master and v0.11. Bees was working overnight for a while, and this morning it hit a particular file that it just got stuck on. In the logs from /run/bees/<uuid>, I see this:
