Created a PR with code to reproduce the issue on CI as I don't have access to arm64 machines: #17782

Running multiple concurrent jobs:

Hmm, still no repro. Are we so unlucky that we hit a bit flip or broken machine?

siyuanfoundation · 2024-04-12T17:46:25Z

I was not able to repro it on my mac (arm64) with 500 runs and failpoint compactBeforeSetFinishedCompact=panic()

Not be able to download the log

The reproduce attempts on linux amd64 machine is also not successful.

We need a persisted audit log to easily replay the traffic. Turn on LogUnaryInterceptor could be a good start.

Not be able to download the log

What do you mean? I was able to download main-arm64.zip from https://github.com/etcd-io/etcd/actions/runs/8659974818 without any problem.

I think we need to assume that this was a hardware issue. One last thing to confirm. Could someone check the bbolt file from the report? Would be a good sanity check that the revision decrease really happen.

@serathius i was able to download and have shared it with Chao (took a few retries .. spotty networking)

chaochn47 · 2024-04-12T19:11:41Z

Somehow I cannot download from the github UI.. Retried multiple times.

@serathius Just to confirm, is it something you were looking for?

I did not observe revision number is decreased but there is some gap between them.

scheduledCompactRev was set to 301 though as expected.

spoke too soon, multiple laptops, different browsers, same issue (zip corrupted)

serathius · 2024-04-12T22:35:42Z

Hmm, last 4 operations before crash were deletes. Defrag removes revisions in Key bucket for keys that were deleted. Etcd infers the last revision based on Key bucket. After restart etcd went back as far as the last put operation. I have a bad feeling about this. cc @ahrtr

serathius · 2024-04-12T22:42:07Z

Will try to increase number of deletes to reproduce a similar case. Looking at the results from couple of runs, the deletes are pretty rare in Kubernetes traffic, possibly request type picker is broken.

Trying to interpret the statement, the difference between the db file key bucket layout and the recorded response is due to compact & defrag after resuming from the panic, right?

But it does not make sense deletion returns response with revision 298 with key /regstry/pods/default/o95Cz but in the db file 298 corresponds to /registry/pods/default/vZJa5. Either the db file is wrong or the etcd responds with incorrect revision number to client.

297 is correct and it is reflected as put in the db file.

The workflow doesn't have any problem. Compact + defragmentation won't remove the last revision, even it's a tombstone revision.

But it does not make sense deletion returns response with revision 298 with key /regstry/pods/default/o95Cz but in the db file 298 corresponds to /registry/pods/default/vZJa5. Either the db file is wrong or the etcd responds with incorrect revision number to client.

The bbolt db file should be correct.

It looks like that the report isn't consistent with regards to revision 298. So it's a bug of the test itself?

With #17815 this issue have been confirmed and reproduced on all supported release branches.

ahrtr · 2024-04-17T18:00:43Z

Root cause

Based on my discussion with @fuweid today, for anyone reference on the root cause of this issue, see below summary.

When latest revision is a tombstone revision, compacting the latest revision will remove the latest revision. It causes the revision decreases in bbolt data file.
If etcd crashes right before it persists the finished compaction revision. Then the finished compact revision isn't persisted to bbolt

etcd/server/storage/mvcc/kvstore_compaction.go

Line 66 in e37a67e

UnsafeSetFinishedCompact(tx, compactMainRev)

When etcd gets started again, it loads all keys and gets the latest revision (already decreased revision) from bbolt. Usually it isn't a problem, because etcd will correct the revision based on the finished compaction revision. It's exactly the reason why previous I did not reproduce it when I raised the comment Revision decreasing after panic during compaction #17780 (comment). But if the finished compact revision hasn't been persisted, then there is no way for etcd to correct the revision.

etcd/server/storage/mvcc/kvstore.go

Line 327 in e37a67e

s.compactMainRev = finishedCompact

etcd/server/storage/mvcc/kvstore.go

Lines 366 to 368 in e37a67e

    
           if s.currentRev < s.compactMainRev { 
        
           	s.currentRev = s.compactMainRev 
        
           }

Versions affected

All versions (3.4.x, 3.5.x, main) have this issue.

For single node cluster, the symptom is the revision decreases.

For multi node cluster, the symptom is not only the revision decreases, but also inconsistent revisions across the etcd cluster.

Note the key/value data is still consistent when this issue is reproduced.

Hard to reproduce

The good news is that this issue should be very hard to reproduce in production environment, because It can only be reproduced when all the following conditions are true,

Compact the latest revision;
The latest revision is a tombstone (a deletion);
etcd crashes after it removes the latest tombstone revision and before it persists the finishedCompactRevision. Obviously it's very small window.

Solution

One proposed solution: #17815 (comment)

Another solution is updating currentRev using the scheduledCompactRevision on bootstrap. See

Workaround

Once it's reproduced, we can use the bump-revision to manually bump the revision to make all etcd instances have consistent revision.

serathius · 2024-04-17T18:14:19Z

With the issue confirmed we need to do impact assessment, check which version it affects, how often it can happen, can it cause inconsistency in multi member cluster and if it can happen in Kubernetes.

The good news is that this issue should be very hard to reproduce in production environment.

Can you provide some context why it should very hard to reproduce, so for everyone can follow? Is it just based on small window of crash vulnerability due to infrequency of compact? How that probability looks for Kubernetes?

Fact that last revision needs to be a tombstone, reduces the chances, but would be good to confirm what percentage do deletes constitute.

Sorry for the confusion. I should be more clearer. Just updated my previous comment.

Thanks, looks great!

Compact the latest revision;

This makes sense, compacting last revision is not expected behavior from most users. Kubernetes built in compaction should almost never do that. "Almost" comes from cases where there were no writes at all for 5 minutes, which is unexpected due to Kubernetes Node Lease and Leader election writing periodically.
