Only the first two, Roaring data and Column-Key -data are relevant here. Broadly, the Roaring bitmap data -forms the central features -- the bits -- of a large, sparse bitmap matrix. -The Column-Keys are the labels for the columns at the top margin of this matrix. - -For speed, the Roaring bitmap data is stored separately from the -Key data. The Roaring data is stored in sharded files -within a directory heirarchy under PILOSA-DATA-DIR/index_name/field_name/... -The Key translation data is stored in sharded BoltDB databases within -the PILOSA-DATA-DIR/index_name/_key directory. - -The current approach to Roaring file replication involves an -eventually consistent mechanism that uses an Anti-Entropy agent to -fix partial or incomplete replication from the primary shard to all -replica shards. - -Unfortunately, the Anti-Entropy agent approach has proved inadequate on two -fronts. First, it does not provide for immediately consistent reads in the -event that the primary is lost. Second, the Anti-Entropy agent itself experienced -out-of-memory issues that have yet to be resolved. - -Therefore, work is now underway to replace this replication -approach with a more consistent design. - -However, in the meantime, for our customers in production with Molecula -Pilosa, we wish to provide a means to re-establish correct replication. -Thus even in the event of a node failure followed by a read from a replica, the -returned read will be correct. - -The pilosa-fsck tool can therefore be seen as a temporary, stop-gap -measure to address immediate issues while the cluster replication -mechanism is replaced. - -The second factor motivating the creation of pilosa-fsck was the discovery -of a bug in the Key-translation process. Unfortunately this was a hard -to reproduce bug. It happened only on the customer's premises, -and only after running the system for a long time, with a -large amount of data, and with various eccentric node failures -and recoveries. - -However, we were able to reproduce a plausible explanation. -Non-primary replicas were creating keys when they should have been -forwarding the request to the primary. Correcting this bug is impetus -for the v2.1.4 release of Molecula Pilosa. - -A fine point here: since we were not able to precisely reproduce the customer's -issue in the development environment, we cannot guarantee with 100% -certainty that we have actually addressed the bug that the customer -was seeing. - -Therefore we also desired an additional insurance -policy. We wished to be able to empower customers to proactively discover any -future Key-translation issues that happen in their on-premise systems. - -To do this, we proposed providing select customers with the pilosa-fsck -tool which can analyze their offline backups for issues. - -Optionally, these issues can also be repaired in-place in the -offline backup on which pilosa-fsck is run. - -The -fix flag repairs both kinds of replication issues. - -Solution Approach: mechanism of action --------------------------------------- - -The pilosa-fsck is run offline on a full set of backups taken from -all nodes in a Pilosa cluster. It runs on a single computer that -must be separate from the production or staging Pilosa environments. - -When run, pilosa-fsck analyzes the differences between the -primary and its replicas. Both the Roaring -files and the Key translation databases are analyzed. -The computer running pilosa-fsck must have the same or more -memory as the Pilosa nodes in the cluster, as it will -"pretend" to be each Pilosa node in turn. However, as each -node's backup is closed before the next node's backup is -opened, we do not require substantially more memory than a single -production node. Short Blake3 cryptographic checksums are -computed for each Roaring fragment and each Key translation -database. These are held in memory (and printed to the log) -for comparing nodes. This comparison forms the heart of -the consistency checks, and is the basis for any subsequent -repair. - -We recommend capturing both stdout and stderr to a log. -Use `&> log` or `2>&1 > log` at the end of the -pilosa-fsck invocation to save a log of the run to disk. - -In a typical cluster, the Replication factor R may be less -than the number of nodes N in the cluster. For example, while -N may be 4, the R may be only 3. In this example, within -each replicated shard, one node will be the primary for -that shard, two nodes will be non-primary replicas, and one -node will be a non-replica. Note that the designation -of primary changes for different Roaring shards within an index, -even on a single node. - -The essence of the the -fix repair operation that pilosa-fsck -can do is this: it will copy from the primary to the -the non-primary replicas. Further, it will remove data from -any non-replica node if it was mistakenly present. - -The pilosa-fsck output log will contain -a sequence of command line 'cp' and 'rm' commands. -These commands are merely a record (with -accompanying justifcation in the comment following the -command) of what actions would be performed to repair -the Roaring file data. - -Only with -fix will the repair actions actually happen -during the pilosa-fsck run. - - -Details: running pilosa-fsck ----------------------------- - -Errors in invocation are reported on stderr and the program will exit with a non-zero -error code if invocation errors are present. A non-zero error code -is returned if a repair is needed and -fix was not given. - -A -fix run will return a zero error code to the shell if the fix was -successfully made; or if no fix was required. - -The log of the run is printed to stdout. - -The -h flag to pilosa-fsck prints a summary of its operation -and a guide to laying out the backup directories. - -The help is reproduced below. - -~~~ -$ pilosa-fsck version: Molecula Pilosa v2.2.1-43-g9dacbccf (Oct 5 2020 1:28PM, 9dacbccf) - -Use: pilosa-fsck -replicas R {-fix} {-q} /backup/1/.pilosa /backup/2/.pilosa ... /backup/N/.pilosa - - -fix - (warning: alters the backed-up node images on disk) copy primary data to replicas to create a consistent cluster. - - -replicas R - (required) R is a positive integer, giving the replicaN or replicator factor for the cluster.
