## C++ version of the "Mark's bench" for Ceph
|
|
|
|
This tool issues random writes to each OSD separately to determine random write
|
|
performance of each specific OSD.
|
|
|
|
## Usage
|
|
|
|
```
|
|
# Create a non-replicated pool named bench
|
|
# PG number (16) should be sufficient for each OSD to get at least 1 PG
|
|
ceph osd pool create bench 16 16 replicated
|
|
ceph osd pool set bench size 1
|
|
|
|
# Benchmark all OSDs which have at least 1 PG in that pool
|
|
./ceph-bench bench osd
|
|
|
|
# Benchmark hosts (print average result per host)
|
|
./ceph-bench bench host
|
|
|
|
# Benchmark a specific OSD
|
|
./ceph-bench bench osd 1
|
|
```
|
|
|
|
