Hi, all I have yet to find a good solution, and some one have any suggestions. I think this is a big problem when you use cache tier. 2015-08-03 liukai 发件人：Kenneth Waegeman kenneth.waege...@ugent.be 发送时间：2015-07-30 17:31 主题：Re: [ceph-users] A cache tier issue with rate only at 20MB

[ceph-users] A cache tier issue with rate only at 20MB/s when data move from cold pool to hot pool

Hi all， A cache tier, 2 hot node with 8 ssd osd, and 2 cold node with 24 sata osd. The public network rate is 1Mb/s and cluster network rate is 1000Mb/s. Using fuse-client to access the files. The issue is: When the files are in hot pool, the copy rate is very fash.
