From 51ebe09f9a988adc9215fa8c7d686163e3e9c3d4 Mon Sep 17 00:00:00 2001 From: Yanqin Jin Date: Mon, 19 Apr 2021 18:10:23 -0700 Subject: [PATCH 001/483] Handle rename() failure in non-local FS (#8192) Summary: In a distributed environment, a file `rename()` operation can succeed on server (remote) side, but the client can somehow return non-ok status to RocksDB. Possible reasons include network partition, connection issue, etc. This happens in `rocksdb::SetCurrentFile()`, which can be called in `LogAndApply() -> ProcessManifestWrites()` if RocksDB tries to switch to a new MANIFEST. We currently always delete the new MANIFEST if an error occurs. This is problematic in distributed world. If the server-side successfully updates the CURRENT file via renaming, then a subsequent `DB::Open()` will try to look for the new MANIFEST and fail. As a fix, we can track the execution result of IO operations on the new MANIFEST. - If IO operations on the new MANIFEST fail, then we know the CURRENT must point to the original MANIFEST. Therefore, it is safe to remove the new MANIFEST. - If IO operations on the new MANIFEST all succeed, but somehow we end up in the clean up code block, then we do not know whether CURRENT points to the new or old MANIFEST. (For local POSIX-compliant FS, it should still point to old MANIFEST, but it does not matter if we keep the new MANIFEST.) Therefore, we keep the new MANIFEST. - Any future `LogAndApply()` will switch to a new MANIFEST and update CURRENT. - If process reopens the db immediately after the failure, then the CURRENT file can point to either the new MANIFEST or the old one, both of which exist. Therefore, recovery can succeed and ignore the other.

This resulted in data races with memtable inserts. The patch changes the code handling these properties to use `MemTable::ApproximateMemoryUsageFast` instead, which returns a cached value backed by an atomic variable. Two test cases had to be updated for this change. `MemoryTest.MemTableAndTableReadersTotal` was fixed by increasing the value size used so each value ends up in its own memtable, which was the original intention (note: the test has been broken in the sense that the test code didn't consider that memtable sizes below 64 KB get increased to 64 KB by `SanitizeOptions`, and has been passing only by accident). `DBTest.MemoryUsageWithMaxWriteBufferSizeToMaintain` relies on completely up-to-date values and thus was changed to use `ApproximateMemoryUsage` directly instead of going through the DB properties. Note: this should be safe in this case since there's only a single thread involved.

The problem with this change is because of important filter use cases: FIFO compaction and SST writer. FIFO "compaction" always uses level 0 so would only use Ribbon filters if specifically including level 0 for the Ribbon filter policy. SST writer sets level_at_creation=-1 to indicate unknown level, and this would be treated the same as level 0 unless fixed. We are keeping the part about committing to permanent schema, which is only changes to API comments and HISTORY.md.

However, it will report a false positive alert on "SST file is ahead of WALs" when one of the CF current log number is greater than the corrupted WAL number (CF contains the data beyond the corrupted WAl) due to a new column family creation during flush. In this case, a new WAL is created (it is empty) during a flush. Also, due to some reason (e.g., storage issue or crash happens before SyncCloseLog is called), the old WAL is corrupted. The new CF has no data, therefore, it does not have the consistency issue. Fix: when checking cfd->GetLogNumber() > corrupted_wal_number also check cfd->GetLiveSstFilesSize() > 0. So the CFs with no SST file data will skip the check here. Note potential ignored inconsistency caused due to fix: empty CF can also be caused by write+delete. In this case, after flush, there is no SST files being generated. However, this CF still have the log in the WAL. When the WAL is corrupted, the DB might be inconsistent.

We fixed a false-positive, but introduced a very rare true-negative which will be triggered in the following conditions: A CF with some delete operations in the last a few queries which will result in an empty CF (those are flushed to SST file and a compaction triggered which combines this file and all other SST files and generates an empty CF, or there is another reason to write a manifest entry for this CF after a flush that generates no SST file from an empty CF). The deletion entries are logged in a WAL and this WAL was corrupted, while the CF's log number points to the next WAL (due to the flush). Therefore, the DB can only recover to the point without these trailing deletions and cause the inconsistent DB status. ## 6.20.0 (04/16/2021) ### Behavior Changes diff --git a/db/db_impl/db_impl_compaction_flush.cc b/db/db_impl/db_impl_compaction_flush.cc index a4c965766..28ad6fd01 100644 --- a/db/db_impl/db_impl_compaction_flush.cc +++ b/db/db_impl/db_impl_compaction_flush.cc @@ -2582,6 +2582,8 @@ void DBImpl::BackgroundCallFlush(Env::Priority thread_pri) { LogBuffer log_buffer(InfoLogLevel::INFO_LEVEL, immutable_db_options_.info_log.get()); + TEST_SYNC_POINT("DBImpl::BackgroundCallFlush:Start:1"); + TEST_SYNC_POINT("DBImpl::BackgroundCallFlush:Start:2"); { InstrumentedMutexLock l(&mutex_); assert(bg_flush_scheduled_); diff --git a/db/db_impl/db_impl_open.cc b/db/db_impl/db_impl_open.cc index d9683a802..684d70d28 100644 --- a/db/db_impl/db_impl_open.cc +++ b/db/db_impl/db_impl_open.cc @@ -1137,11 +1137,29 @@ Status DBImpl::RecoverLogFiles(const std::vector& wal_numbers, immutable_db_options_.wal_recovery_mode == WALRecoveryMode::kTolerateCorruptedTailRecords)) { for (auto cfd : *versions_->GetColumnFamilySet()) { - if (cfd->GetLogNumber() > corrupted_wal_number) { + // One special case cause cfd->GetLogNumber() > corrupted_wal_number but + // the CF is still consistent: If a new column family is created during + // the flush and the WAL sync fails at the same time, the new CF points to + // the new WAL but the old WAL is curropted.

Some operations can fail before and after the operations take place. If DB open fails, db_stress would retry without the failure ingestion, and DB is expected to open successfully. This option is enabled in crash test in half of the time. Some follow up changes would allow write failures in open time, and ingesting those failures in non-DB open cases. Pull Request resolved: https://github.com/facebook/rocksdb/pull/8235 Test Plan: Run stress tests for a while and see failures got triggered. This can reproduce the bug fixed by https://github.com/facebook/rocksdb/pull/8192 and a similar one that fails when fsyncing parent directory.
