If you have other hardware, i would recommend you try it. Even the system disk is overly busy, probably just from the act of gathering node stats which is something unrelated to Ceph. The system is very slow but i am not able to see a specific bottleneck. Quote from admin on April 5, 2018, 3:25 pm Is this config significantly increase write speed? Question is - if i buy SSD and the config is to be: I don't have RAID Controllers with write cache or SSD disks for journal. I tried Petasan 1.5 and 2.0 - results are similar. I tried on other vm client - speed is exactly the same. Next i created iSCSI disk with 2 active paths on iSCSI1 subnet (cause iSCSI2 subnet is not visible for clients).Ĭopy large file from iSCSI disk to client (physical windows 7 host) - 90MB/secĬopy large file from client to iSCSI disk - 368kB/sec !!! (speed is continuesly decreased from 60MB/sec and stabilized at this number about a half of hour after ) Where 10.10.2.0/24 is a Backend2 network on eth1 Quote from sds80 on April 4, 2018, 9:21 am
