Hello,
I made some tests on 3 node Ceph cluster: upload 3 million 50 KiB object to single container. Speed and performance were okay. But data does not distributed correctly. Every node has got 2 pcs. 4 TB and 1 pc. 2 TB HDD.osd.0 41 GB (4 TB)
osd.1 47 GB (4 TB)
osd.3 16 GB (2 TB)
osd.4 40 GB (4 TB)
osd.5 49 GB (4 TB)
osd.6 17 GB (2 TB)
osd.7 48 GB (4 TB)
osd.8 42 GB (4 TB)
osd.9 18 GB (2 TB)
Every 4 TB and 2 TB HDDs are from same vendor and same type. (WD RE SATA)
I monitored iops with Zabbix under test, you can see here: http://ctrlv.in/237368
(sda and sdb are system HDDs) This graph are same on every three nodes.
Is there any idea what's wrong or what should I see?
