Re: [ceph-users] Replication strategy, write throughput

Hello, 2 parallel jobs with one job simulating the journal (sequential writes, ioengine=libaio, direct=1, sync=1, iodeph=128, bs=1MB) and the other job simulating the datastore (random writes of 1MB)? To test against a single HDD? Yes, something like that, the first fio job would need go
