Dear Cepher, I have a requirement to use CephFS as a tiered file system, i.e. the data will be first stored onto an all-flash pool (using SSD OSDs), and then automatically moved to an EC coded pool (using HDD OSDs) according to threshold on file creation time (or access time). The reason for such a file system is due to the fact that, files are created and most likely accessed within the first 6 months or 1 year, and after that period, those files have much less chance to be accessed and thus could be moved to a slower and cheap pool.
Does CephFS already support such a tiered feature? and if yes, how to implement such feature with a pool of all SSD pool and a pool of EC-coded HDD pool? Any suggestion, ideas, comments are highly appreciated, best regards, samuel huxia...@horebdata.cn _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-le...@ceph.io
