As a follow up: I created another replicated striped volume – two brick replica, striped against two sets of servers (four servers in all) – same config as mentioned below. I started pouring data into it, and here’s my output
from `du`: peer1 - 47G peer2 - 47G peer3 - 47G peer4 - 24G Peer1 and Peer2 should be mirrored, and peer3 and peer4 should be mirrored. This time, data seems more balanced – EXCEPT that peer4 continues to lag FAR behind – like in the example below. Any suggestions would be appreciated.

On Behalf Of Kiebzak, Jason M. It seems that I have two issues: 1)
Data is not balanced between all bricks 2)
one replication “pair” is not staying in sync I have four servers/peers, each with one brick, all running 3.6.1. There are two volumes, each running as distributed replicated volume. Below, I’ve included some info. All Daemon are running.
The four peers were all added at the same time. Problem 1) for volume1, the peer1/peer2 set have 236G, while peer3 has 3.9T. Shouldn’t it be split more evenly – close to 2T on each set of servers? A similar issue is seen with volume2, but
the total data set (thus the diff) is not as large. Problem 2) peer3 and peer4 should be replicated to each other. Peer1 and peer2 have identical disk usage, where as peer3 and peer4 are egregiously out of sync. Data on both peer3 and peer4
continues to grow (I am actively migrating 50T to volume 1). `gluster volume info` give this: Volume Name: volume1 Type: Distributed-Replicate Volume ID: bf461760-c412-42df-9e1d-7db7f793d344 Status: Started Number of Bricks: 2 x 2 = 4 Transport-type: tcp Bricks: Brick1: ip1:/data/volume1 Brick2: ip2:/data/volume1 Brick3: ip3:/data/volume1 Brick4: ip4:/data/volume1 Options Reconfigured: features.quota: on auth.allow: serverip Volume Name: volume2 Type: Distributed-Replicate Volume ID: 54a8dbee-387f-4a61-9f67-3e2accb83072 Status: Started Number of Bricks: 2 x 2 = 4 Transport-type: tcp Bricks: Brick1: ip1:/data/volume2 Brick2: ip2:/data/volume2 Brick3: ip3:/data/volume2 Brick4: ip4:/data/volume2 Options Reconfigured: auth.allow: serverip If I do a `# du –h --max-dpeth=1` on each peer, I get this: Peer1 236G /data/volume1 177G /data/volume2 Peer2 236G /data/volume1 177G /data/volume2 Peer3 3.9T /data/volume1 179G /data/volume2 Peer4 524G /data/volume1 102G /data/volume2 |
