I'm not speaking to anything other than your configuration. "I am using 2 x 10 GB bonded ( BONDING_OPTS="mode=4 miimon=100 xmit_hash_policy=1 lacp_rate=1") for cluster and 1 x 1GB for public" It might not be a bad idea for you to forgo the public network on the 1Gb interfaces and either put

Re: [ceph-users] Luminous - bad performance

Disk models, other hardware information including CPU, network config? You say you're using Luminous, but then say journal on same device. I'm assuming you mean that you just have the bluestore OSD configured without a separate WAL or DB partition? Any more specifics you can give will be

Hi, I'll appreciate if you can provide some guidance / suggestions regarding perfomance issues on a test cluster ( 3 x DELL R620, 1 Entreprise SSD, 3 x 600 GB ,Entreprise HDD, 8 cores, 64 GB RAM) I created 2 pools ( replication factor 2) one with only SSD and the other with only HDD ( journal on
