* geo-rep: get new config value after config value resetAravinda VK2014-01-231-0/+1
| | | | | | | | | | | | | | | | | | | | When config.read is called it preserves the previous values from the the previously opened config file. For example import ConfigParser config = ConfigParser.RawConfigParser() config.read("defaults.conf") config.read("preferences.conf") When change in config file is identified it will open new instance of config to avoid getting old config values.

* geo-rep: optimizing update stime after directory synchronizationAravinda VK2014-01-221-6/+14
| | | | | | | | | | | | | | | | | | | | | Since xsync crawl generates new changelog when number of entries reaches 8K or when directory is reached. If a directory has number of files less than 8K then respective changelog file will have less entries. Since xsync generated changelog files processed one after the other, so syncjobs are underutilized. hence low bandwidth utilization. With this patch, changelog will be generated for 8K entries only, but stime will be accumulated. Multiple dirs stime will be updated together since the generated changelog will have entries accross the dirs.

* geo-rep: logrotate: Logrotate handlingAravinda VK2013-10-032-15/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In existing georep logrotate was implemented by handling SIGSTOP and SIGCONT, gsyncd was failing to start again after SIGSTOP. New approach uses WatchedFileHandler in logging, which tracks the log file changes or logrotate. Reopens the log file if logrotate is triggered or if same log file is updated from other process. As per python doc: http://docs.python.org/2/library/logging.handlers.html: The WatchedFileHandler class, located in the logging.handlers module, is a FileHandler which watches the file it is logging to. If the file changes, it is closed and reopened using the file name. A file change can happen because of usage of programs such as newsyslog and logrotate which perform log file rotation. This handler, intended for use under Unix/Linux, watches the file to see if it has changed since the last emit. (A file is deemed to have changed if its device or inode have changed.) If the file has changed, the old file stream is closed, and the file opened to get a new stream.

* gsyncd / geo-rep: "disjoint" cascading geo-replication sessionsVenky Shankar2013-09-041-100/+33
| | | | | | | | | | | | | | | | | | | | | | | | Slave's xtime is now stored on the master itself (and that too only on the root), which implies it cannot be propogated to the cascaded slave. Thus the intermediate master now makes use of it's own volume information to propogate volume-mark and xtime. On starting Geo-Replication "geo-replication.ignore-pid-check" marker option is enabled, which is an override for the client-pid check in marker. This options triggers marker update only for geo-replication auxillary mount (client-pid == -1). Since gsyncd not does setxattr() directly on the bricks, this option won't trigger a chain of spurious metadata updates that would need to be processed by gsyncd.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This mode introduces and optimized recovery of master, used during failover-failback cases. Files are only transferred if they are identified as changed on the slave. A normal failback mechanism would be just to reverse the direction of geo-replication syncing. Doing this is the correct way but could be time consuming. "Recovery" mode optimizes this by identifying files (as skipping them) duing the one-shot crawl. NOTE: Use this mode when you are _absolutely_ sure that the namespace on the master is intact, ie. there is number of files in master is equal to the number of files in the slave, but the slave was written to (after a failover) when master was brought back up. - gluster volume geo <MV> <SLAVE>::<SV> config special_sync_mode recover - gluster volume geo <MV> <SLAVE>::<SV> start Change-Id: Idb698949e4e86698b15d04a35d33095562f51714 BUG: 994462 Original Author: Venky Shankar <vshankar@redhat.com> Signed-off-by: Venky Shankar <vshankar@redhat.com> Reviewed-on: http://review.gluster.org/5515 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Avra Sengupta <asengupt@redhat.com> Tested-by: Avra Sengupta <asengupt@redhat.com> Reviewed-by: Anand Avati <avati@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | This patch extends the persistent instrumentation work done by Aravinda (@avishwa), by introducing a handfull of instrumentation variables for crawl. These variables are "pulled up" by glusterd in the event of a geo-replication status cli command and looks something like below: "Uptime=00:21:10;FilesSyned=2982;FilesPending=0;BytesPending=0;DeletesPending=0;" "FilesPending", "BytesPending" and "DeletesPending" are short-lived variables that are non-zero when a changelog is being processes (ie. when an active sync in ongoing). After a successfull changelog process "FilesPending" is summed up into "FilesSynced". The three short-lived variabled are then reset to zero and the data is persisted Additionally this patch also reverts some of the changes made for BZ #986929 (those were not needed).
