* geo-rep: Failover when a Slave node goes downAravinda VK2014-11-121-5/+64
| | | | | | | | | | | | | | | | | | | When a slave node goes down, worker in master node can connect to different slave node and resume the operation. Existing georep was not checking the status of slave node before worker restart. With this patch, geo-rep worker will check the node status using `gluster volume status` when it goes faulty.

* geo-rep: Fix rename of directory syncing.Kotresh HR2014-09-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | The rename of directories are captured in all distributed brick changelogs. gsyncd processess these changelogs on each brick parallellaly. The first changelog to get processed will be successful. All subsequent ones will stat the 'src' and if not present, tries to create freshly on slave. It should be done only for files and not for directories. Hence when this code path was hit, regular file's blob is sent as directory's blob and gfid-access translator was erroring out as 'Invalid blob length' with errno as 'ENOMEM' Change-Id: I50545b02b98846464876795159d2446340155c82 BUG: 1147422 Signed-off-by: Kotresh HR <khiremat@redhat.com> Reviewed-on: http://review.gluster.org/8865 Reviewed-by: Aravinda VK <avishwan@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Venky Shankar <vshankar@redhat.com> Tested-by: Venky Shankar <vshankar@redhat.com> Reviewed-on: http://review.gluster.org/8880 Reviewed-by: Vijay Bellur <vbellur@redhat.com>

* geo-rep: minimize xsync crawl usage and set upper limit to xsync crawlAravinda VK2014-09-082-38/+118
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For effective handling of deletes and renames use history crawl as much as possible. History crawl will run in loop till it syncs all data before live changelog time. When it uses xsync crawl(fallback when changelog not available, or very first crawl) it sets upper limit to crawl. After completing History crawl, it checks actual end time returned by history api to compare with register time, if actual end is less than register time then run history crawl one more time. If first turn history processing time is less than the CHANGELOG ROLLOVER TIME then sleep for the difference, After sleep if it is guaranteed that rollover will happen and switches to live changelog consumption without switching to xsync. This sleep is only when history processing completed < CHANGELOG_ROLLOVER_TIME and sleep only after the first turn, So will not affect the performance.

* gsyncd / geo-rep: Partial support for Non-root geo-replication.Venky Shankar2014-05-142-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | This patch enables geo-replication to be run as an unprivileged user. As of now, this is just the partial support, but is very close to achieve full functionality. Current limitation * Geo-replication executed Gluster CLI commands on the slave via SSH. On a non-root setup, Gluster CLI would run as an unprivileged user, failing to execute the command. As a workaround (for testing), setuid(2) Gluster CLI executable or use the glusterd option to accept commands by unprivileged CLI process. The nature of cli commands are "system::" commands (for key management) and remote volume info fetching. Remote volume info fetching has been modified to use --remote-host gluster cli option rather than ssh and remote cli execution.

| | | | | | | | | | | | | | | | | | | | | | | | Every time when geo-rep restarts it first does FS crawl using XCrawl and then switches to Changelog Mode. This is because changelog only had live API, that is we can get changes only after registering. Now this(http://review.gluster.org/#/c/6930/) patch introduces History API for changelogs. If history is available then geo-rep will use it instead of FS Crawl. History API returns TS till what time history is available for given start and end time. If TS < endtime then switch to FS Crawl. (History => FS Crawl => Live Changelog) If TS >= endtime, then switch directly to Changelog mode (History => Live Changelog) Change-Id: I4922f62b9f899c40643bd35720e0c81c36b2f255 Signed-off-by: Aravinda VK <avishwan@redhat.com> Reviewed-on: http://review.gluster.org/6938 Reviewed-by: Venky Shankar <vshankar@redhat.com> Reviewed-by: Humble Devassy Chirammal <humble.devassy@gmail.com> Tested-by: Gluster Build System <jenkins@build.gluster.com>
