Hi all,
I'm working on filling a cluster to near capacity for testing purposes.
Though I'm noticing that it isn't storing the data uniformly between OSDs
during the filling process. I currently have the following levels:
Node 1:
/dev/sdb1 3904027124 2884673100 1019354024
74% /var/lib/ceph/osd/ceph-0
/dev/sdc1 3904027124 2306909388 1597117736
60% /var/lib/ceph/osd/ceph-1
/dev/sdd1 3904027124 3296767276 607259848
85% /var/lib/ceph/osd/ceph-2
/dev/sde1 3904027124 3670063612 233963512
95% /var/lib/ceph/osd/ceph-3
Node 2:
/dev/sdb1 3904027124 3250627172 653399952
84% /var/lib/ceph/osd/ceph-4
/dev/sdc1 3904027124 3611337492 292689632
93% /var/lib/ceph/osd/ceph-5
/dev/sdd1 3904027124 2831199600 1072827524
73% /var/lib/ceph/osd/ceph-6
/dev/sde1 3904027124 2466292856 1437734268
64% /var/lib/ceph/osd/ceph-7
I am using "rados put" to upload 100g files to the cluster, doing two at a
time from two different locations. Is this expected behavior, or can
someone shed light on why it is doing this? We're using the opensource
version 80.7. We're also using the default CRUSH configuration.
