Release date: February 13, 2014
Major features and changes in this version:
- Filesystem disaster recovery features (especially for Lustre)
- for more details: see robinhood 2.5 Disaster Recovery Guide.
- New namespace management (new DB schema to properly handle hardlinks, rename operations...)
- Scanning and changelog processing optimizations
- Database optimizations (requests batching)
- Many other changes, improvements and code cleaning...
rbh-diff:
- new command to detect differences between the filesystem and the information in robinhood database.
- option "--apply=fs" for disaster recovery purpose: restore the filesystem metadata from robinhood DB.
- makes it possible to rebuild a Lustre MDT from scratch, or from a LVM snapshot
database:
- new namespace implementation in database with new NAMES table (Cray contribution)
- fixes/improves hardlink support
- fixes/improves Lustre ChangeLog hardlink/rename/unlink support
- saves DB storage space
- database request batching: significantly increase database ingest rate. No longer needs innodb_flush_log_at_tx_commit != 1 to speed up DB operations.
- additional information in DB that can help for disaster recovery:
- set default commit behavior to transaction (prevent from DB inconsistencies)
- optimized multi-table requests
- optimization: minimized attribute set in DB update operations
- Fix: deal with mysql case insensitivity for string matching
- triggers and stored procedures versioning mechanism
- prevent from overflows for large INSERT requests, wide stripes...
- prevent from DB deadlocks
- --partial-scan option is deprecated and replaced by an optional argument to --scan (e.g. --scan=/fs/subdir).
- better management of partial scans:
- better detection of removed entries vs. entries moved from a directory to another.
- partial scans can be used for initial DB population (even if the DB is initially empty).
- dealing with dead/deactivated OSTs: don't remove entries from DB if stat() returns ESHUTDOWN.
- garbage collection of removed entries in DB is a long operation when terminating a scan (and even more when terminating a partial scan). Added --no-gc option to skip it (recommanded for partial scans).
- automatically enabling --no-gc if the DB is initially empty (eg. for initial scan).
- optimization: use *at() functions (openat, fstatat) and readdir by chunk (using getdents) instead of POSIX lstat() and readdir_r().
- optimization: use NOATIME flag to access entries as much as possible
- optimizations of get_stripe and get_fid operations.
- new --diff option for robinhood --scan and --readlog: output detected changes in a diff-like format.
- changelog batching (Cray contribution): to speed up changelog processing, robinhood retains changelog records in memory a short time, to aggregate similar/redundant Changelog records on the same entry before updating its database.
- support multiple changelog readers (for DNE) as multiple threads (default) or as multiple processes, possibly on different hosts, by giving a MDT index to --readlog option.
- resilience to filesystem umount/mount.
- new option --entry-info to get all the stored information about an entry
- option --dump-ost can now list multiple OSTs and support ranges notation (e.g. 3,5-8,12-23).
- --dump-ost output indicates if a file has data on a given OST (could be striped on the OST but have no data on it).
- new option -crtime to filter entries on creation time.
- output ordering closer to find output
- added missing info in 'rbh-find -ls' output (nlink, mode, symlink info...)
- by default, use a built-in copy function to avoid the cost of forking copy commands.
- rbh-backup-rebind: tool to rebind an entry in the backend if its fid changed in the filesystem for any reason (file copied to a new one to change its stripe, etc...)
- rbh-backup-recov new features and options:
- --list (list information about entries to be recovered)
- --ost <ost_set></ost_set> to only recover entries for a given set of OSTs (support range notation): the basic use-case is OST disaster recovery.
- --since <time></time> to only recover entries modified since a given date: the basic use case is after restoring an OST snapshot.
- symlinks archiving to backend made optional (new parameter 'archive_symlinks') as they can now be restored using robinhood database information.
- new parameter: sync_archive_data: force sync'ing data to disk to finalize the copy.
- can specify environment variables in config file (e.g. fs_path = $ROOT_DIR ;)
- prevent from using a wrong config file (Cray contribution):
- only check files in /etc/robinhood.d/<purpose></purpose>, no longer in the current directory
- fails if to many config files are available.
- added man pages for robinhood daemon, rbh-report, rbh-find
