Could you please let me know if CephFS is supporting Erasure coded pool in the backend or not ? > If not, is there any plan of supporting this kind of configuration in near future ? You can set replicated cache pools, positioned as tiers over an EC pool, as data pools for CephFS. You cannot use EC pools directly for CephFS. We have no plans to add support for EC pools in the foreseeable future — since they have limited RADOS functionality we'd need to implement a whole log-structured file storage system or something. :( -Greg > > Thanks & Regards > Somnath > > ________________________________ > > PLEASE NOTE: The information contained in this electronic mail message is intended only for the use of the designated recipient(s) named above.
