I have few queries about this data movement.I can see the data movement on the following cases. 1. Source sub-volume is 90% occupied and destination sub-volume is 98% occupied. log info [2015-08-26 06:53:26.219674] I [MSGID: 109022] [dht-rebalance.c:1282:dht_migrate_file] 0-qubevaultdr-dht: completed migration of /Packages/Features/MPEG/B/BrokenHorses_FTR_S_EN-en_INT-XX_51_HD_RIM_IOP_OV/BrokenHorses_FTR_S_EN-en_INT-XX_51_HD_20150401_RIM_IOP_OV/BROKEN-HORSES_EN-en_INT_REV_MPEG-reel-3-mpeg2.mxf from subvolume qubevaultdr-disperse-7 to qubevaultdr-disperse-10 Can you mention whether you gave force option while starting rebalance? If force flag is set, rebalance will move the data with out considering whether it is moving the data from a high avail space to a low avail space. 2. Source sub-volume is 98% occupied and destination sub-volume is 97% occupied log info [2015-08-26 06:52:18.071802] I [dht-rebalance.c:1002:dht_migrate_file] 0-glustertest-dht: /Packages/Features/MPEG/B/Broker2_FTR_S_TE-XX_IN-A_51_HD_RIH_IOP_OV/Broker2_FTR-V1_ S_TE-XX_IN-A_51_HD_20140526_RIH_IOP_OV/BROKER-2_R3_MPEG_AUDIO_250514.mxf: attempting to move from glustertest-disperse-10 to glustertest-disperse-8 3. source sub-volume is 94% occupied and destination sub-volume is 15% occupied log info [2015-08-26 06:53:26.348804] I [MSGID: 109022] [dht-rebalance.c:1282:dht_migrate_file] 0-glustertest-dht: completed migration of /Packages/Features/MPEG/B/Broker2_FTR_S_TE-XX_IN-A_51_HD_RIH_IOP_OV/Broker2_FTR-V1_S_TE-XX_IN-A_51_HD_20140526_RIH_IOP_OV/ASSETMAP from sub-volume glustertest-disperse-26 to glustertest-disperse-56 I can see the case 2 and 3 are valid cases because source has more data than destination. But Case 1 is invalid, because source sub-volume has less data than destination sub-volume. Also i have one more query about case 2. Why does the case 2 choose the destination as 94% occupied sub-volume instead of so many under utilized sub-volumes( 13% to 15 % sub-volumes- glustertest-disperse-36 to glustertest-disperse-71 ) ?

Actually we are archiving video files on this cluster. I think there is a bug in cluster.min-free-disk. Also i would like to know about rebalance the cluster. Currently we have 20 nodes and 10 nodes hard disks are almost full . So we need to rebalance the data. If i run the rebalancer, it starts on first node(node1) and starts the migration process. The first node cpu usage is always high during rebalance compare with rest of the cluster nodes.To reduce the cpu usage of rebalancer datanode( node1), i peer a new node( without disk) for rebalance and start the rebalancer. It starts again the rebalancer on same node1. How can we run a rebalancer on a dedicated node? Also we are facing memory leaks in fixlayout and heal full operations.

If you happen to write to the existing files on the brick and that is leading to brick getting full, then most probably you should run a rebalance.
