And this happens only with hybrid crawl. Consistently reproducible. During start of hybrid crawl, crawler stores masters xtime in memory. After completion of crawl and sync, it will update the same xtime for slave. If files created after crawler started, then checkpoint time will be more than the last saved xtime in memory, so even after completion it shows checkpoint is not reached. This is expected behavior, if we update the latest xtime instead of xtime stored in memory, their are chances of data loss. Vijaykumar, was I/O done on the mount after checkpoint was set? If yes, then isn't this the expected behaviour? Verified with build: glusterfs-3.7.1-7.el6rhs.x86_64 Tried both the below scenarios: a. Have the files before creation of geo-rep session so as to use HYBRID CRAWL b. Change the change_detector to xsync to use HYBRID CRAWL In both the above cases, the last sync is not update. In the first case, Last sync is N/A and in the second case, last sync shows when the last changelog was synced. Eventually in Hybrid Crawl, the checkpoint completed Remains always as NO even when the files are synced to slave. Moving this bug to Assigned state.
