Hi David,
Thank you for your response.
My configuration is 50gb/200gb/300gb for flood/high/low. i have a single index being written to and many other read only indices (using rollover API). As i said before i have 10 data nodes in the cluster with varying disk sizes - from 1.5TB to 4.3TB. The "big" machines have multiple disks. all shards are ~50gb (give or take 1gb).
monitoring is also enabled on this cluster so i have lots of system indices (kibana, es, logstash).
I have not modified any cluster configuration other than the limits stated above. i did notice the disk getting filled is the first one in configuration array. This issue doesn't seem to happen on other machines with multiple disks when disks are the same size.
is there any other information i can provide? also, are there any recommendation for such setups (single index rolling over, many data nodes with varying disk sizes)?
Thanks a lot,
Itamar.
