* build: Better configure control & messages for xml outputKaushal M2013-08-011-7/+18
| | | | | | | | | | | | | | | | | | | | Users were not given a correct indication to whether xml output was going to be built on running configure as the only information was lost in the checks output. This would lead to conditions where the user would assume gluster was compiled with xml output, when it wasn't the case. With this change, a new line is added to the end of the configure output which indicates if xml output is being built or not. Also, a new configure flag, '--disable-xml-output', has been introduced which can be used to explicitly disable xml outpu from being built.

* dht: make linkfile creation mode explicitly get setAnand Avati2013-07-311-0/+9
| | | | | | | | | | | | | | | | Because of posix default_acl on parent directory, the mode of linkfile can get masked with the mode in the default acl. This breaks DHT integrity. So let the mode get explicitly reset after mknod().

| | | | | | | | | | | | | | | Performing syncop_create() on a pre-existing file can result in opening the linkfile if DHT has a linkfile for the file. This is because dht_create() will perform the op on the hashed_subvol() and overwrite the layout in dht_create_cbk.

* storage/posix: implement batched fsync in a single threadAnand Avati2013-07-235-1/+288
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Because of the extra fsync()s issued by AFR transaction, they could potentially "clog" all the io-threads denying unrelated operations from making progress. This patch assigns a dedicated thread to issues fsyncs, as an experimental feature to understand performance characteristics with the approach. As a basis, incoming individual fsync requests are grouped into batches, falling in the same @batch-fsync-delay-usec window of time. These windows can extend in practice, as processing of the previous batch can take longer than @batch-fsync-delay-usec while new requests are getting batched. The feature support three modes (similar to the -S modes of fs_mark) - syncfs: In this mode one syncfs() is issued per batch, instead of N fsync()s (one per file.) - syncfs-single-fsync: In this mode one syncfs() is issued per batch (which, on Linux, guarantees the completion of write-out of dirty pages in the filesystem up to that point) and one single fsync() to synchronize or flush the controller/drive cache. This corresponds to -S 2 of fsmark. - syncfs-reverse-fsync: In this mode, one syncfs() is issued per batch, and all the open files in that batch are fsync()'ed in the reverse order of the queue. This corresponds to -S 4 of fsmark. - reverse-fsync: In this mode, no syncfs() is issued and all the files in the batch are fsync()'ed in the reverse order. This corresponds to -S 3 of fsmark.

* features/changelog: changelog translatorAvra Sengupta2013-07-2235-16/+5053
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the initial version of the Changelog Translator. What is it ----------- Goal is to capture changes performed on a GlusterFS volume. The translator needs to be loaded on the server (bricks) and captures changes in a plain text file inside a configured directory path (controlled by "changelog-dir", should be somewhere in <export>/.glusterfs/changelog by default). Changes are classified into 3 types: - Data: : TYPE-I - Metadata : TYPE-II - Entry : TYPE-III Changelog file is rolled over after a certain time interval (defauls to 60 seconds) after which a changelog is started. The thing to be noted here is that for a time interval (time slice) multiple changes for an inode are recorded only once (ie. say for 100+ writes on an inode that happens within the time slice has only a single corresponding entry in the changelog file). That way we do not bloat up the changelog and also save lots of writes. Changelog Format ----------------- TYPE-I and TYPE-II changes have the gfid on the entity on which the operation happened. TYPE-III being a entry op requires the parent gfid and the basename. Changelog format has been kept to a minimal and it's upto the consumers to do the heavy loading of figuring out deletes, renames etc.. A single changelog file records all three types of changes, with each change starting with an identifier ("D": DATA, "M": METADATA and "E": ENTRY). Option is provided for the encoding type (See TUNABLES). Consumers ---------- The only consumer as of today would be geo-replication, although backup utilities, self-heal, bit-rot detection could be possible consumers in the future. CLI ---- By default, change-logging is disabled (the translator is present in the server graph but does nothing). When enabled (via cli) each brick starts to log the changes. There are a set of tunable that can be used to change the translators behaviour: - enable/disable changelog (disabled by default) gluster volume set <volume> changelog {on|off} - set the logging directory (<brick>/.glusterfs/changelogs is the default) gluster volume set <volume> changelog-dir /path/to/dir - select encoding type (binary (default) or ascii) gluster volume set <volume> encoding {binary|ascii} - change the rollover time for the logs (60 secs by default) gluster volume set <volume> rollover-time <secs> - when secs > 0, changelog file is not open()'d with O_SYNC flag - and fsync is trigerred periodically every <secs> seconds. gluster volume set <volume> fsync-interval <secs> features/changelog: changelog consumer library (libgfchangelog) A shared library is provided for the consumer of the changelogs for easy acess via APIs. Application can link against this library and request for changelog updates. Conversion of binary logs to human-readable ascii format is also taken care by the library which keeps a copy of the changelog in application provided working directory.

For example, gf_openlog (NULL, -1, -1); gf_syslog (GF_ERR_DEV, LOG_ERR, "error reading configuration file"); Using syslog, admin is free to configure logger to * reduce repeated log messages * forward logs to remote logger * execute a command on certain log pattern * alert people for certain log pattern by email, snmp etc * and many more Change-Id: Ibacbcbbc547192893fc4a46b387496b622e4811f BUG: 928648 Signed-off-by: Bala.FA <barumuga@redhat.com> Reviewed-on: http://review.gluster.org/4915 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Vijay Bellur <vbellur@redhat.com>
