Can't say I saw that on our cluster.
- 3 Nodes
- 3 OSD's per Node
- SSD journals for each OSD.
- 2*1G Eth in LACP Bond dedicated to Ceph
- 1G Admin Net
- Size = 3 (Replica 3)
Never came close to maxing out 1 1Gbps connection, write throughput and
IOPS are terrible. Read is pretty good though.
Currently trialing Gluster 3.7.11 on ZFS Bricks, Replica 3 also. Triple
the throughput ans IOPS I was getting with Ceph, maxes out the 2*1G
connection, also seems to deal with VM I/O spikes better too, not
letting other VM's be stalled.
Not convinced its as robust as Ceph yet, give it a few more weeks. It
does cope very well with failover and brick heals (using 64MB shards).
