Dear all, now i faced one issue in ceph block device: performance degradation
ceph version 0.61.2 (fea782543a844bb277ae94d3391788b76c5bee60)
ceph status
health HEALTH_OK
monmap e1: 2 mons at {a=49.213.67.204:6789/0,b=49.213.67.203:6789/0}, election
epoch 20, quorum 0,1 a,b
osdmap e53: 2 osds: 2 up, 2 in
pgmap v535: 576 pgs: 576 active+clean; 11086 MB data, 22350 MB used, 4437 GB /
4459 GB avail
mdsmap e29: 1/1/1 up {0=a=up:active}, 1 up:standby
I do benchmark with one osd, I receive the io speed is about 190MB/s
But When i add more osd, replicate size =2 , the write performance degradated
is about 90MB/s
Follow the pratice, the write performance must be increated as adding more osd
but I can't receive that. :(
anyone can you help me check what's wrong in config file or anything else?
Regards,
Khanh Nguyen
