Description of problem: ======================= While converting 2x2 to 2x(2+1) (arbiter), there was a checksum mismatch: [root@dhcp43-143 ~]# ./arequal-checksum -p /mnt/master/ Entry counts Regular files : 10000 Directories : 2011 Symbolic links : 11900 Other : 0 Total : 23911 Metadata checksums Regular files : 5ce564791c Directories : 288ecb21ce24 Symbolic links : 3e9 Other : 3e9 Checksums Regular files : 8e69e8576625d36f9ee1866c92bfb6a3 Directories : 4a596e7e1e792061 Symbolic links : 756e690d61497f6a Other : 0 Total : 2fbf69488baa3ac7 [root@dhcp43-143 ~]# ./arequal-checksum -p /mnt/slave/ Entry counts Regular files : 10000 Directories : 2011 Symbolic links : 11900 Other : 0 Total : 23911 Metadata checksums Regular files : 5ce564791c Directories : 288ecb21ce24 Symbolic links : 3e9 Other : 3e9 Checksums Regular files : 53c64bd1144f6d9855f0af3edb55e614 Directories : 4a596e7e1e792061 Symbolic links : 756e690d61497f6a Other : 0 Total : 3901e39cb02ad487 Everything matches except under "CHECKSUMS", Regular files and the total are a mismatch. Version-Release number of selected component (if applicable): ============================================================== glusterfs-3.12.2-45.el7rhgs.x86_64 How reproducible: ================= 2/2 Steps to Reproduce: ==================== 1. Create and start a geo-rep session with master and slave being 2x2 2. Mount the vols and start pumping data 3. Disable and stop self healing (prior to add-brick) # gluster volume set VOLNAME cluster.data-self-heal off # gluster volume set VOLNAME cluster.metadata-self-heal off # gluster volume set VOLNAME cluster.entry-self-heal off # gluster volume set VOLNAME self-heal-daemon off 4. Add brick to the master and slave to convert them to 2x(2+1) arbiter vols 5. Start rebalance on master and slave 6. Re-enable self healing : # gluster volume set VOLNAME cluster.data-self-heal on # gluster volume set VOLNAME cluster.metadata-self-heal on # gluster volume set VOLNAME cluster.entry-self-heal on # gluster volume set VOLNAME self-heal-daemon on 7. Wait for rebalance to complete 8. Check the checksum between master and slave Actual results: =============== Checksum does not fully match Expected results: ================ Checksum should match
