This is prehistoric ceph version ;) you should use repository from ceph.com http://ceph.com/docs/master/install/get-packages/#getting-packages ----- Mail original ----- De: "Listas@Adminlinux" <lis...@adminlinux.com.br> À: ceph-users@lists.ceph.com Envoyé: Vendredi 23 Mai 2014 20:31:35 Objet: [ceph-users] Designing a cluster with ceph and benchmark (ceph vs ext4) Hi ! I have failover clusters for some aplications. Generally with 2 members configured with Ubuntu + Drbd + Ext4. For example, my IMAP cluster works fine with ~ 50k email accounts and my HTTP cluster hosts ~2k sites. See design here: http://adminlinux.com.br/cluster_design.txt I would like to provide load balancing instead of just failover. So, I would like to use a distributed architecture of the filesystem. As we know, Ext4 isn't a distributed filesystem. So wish to use Ceph in my clusters. Any suggestions for design of the cluster with Ubuntu+Ceph? I built a simple cluster of 2 servers to test simultaneous reading and writing with Ceph. My conf: http://adminlinux.com.br/ceph_conf.txt But in my simultaneous benchmarks found errors in reading and writing. I ran "iozone -t 5 -r 4k -s 2m" simultaneously on both servers in the cluster. The performance was poor and had errors like this: Error in file: Found ?0? Expecting ?6d6d6d6d6d6d6d6d? addr b6600000 Error in file: Position 1060864 Record # 259 Record size 4 kb where b6600000 loop 0 Performance graphs of benchmark: http://adminlinux.com.br/ceph_bench.html Can you help me find what I did wrong?
