Re: Cephfs on an EC Pool - What determines object size

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



CephFS automatically chunks objects into 4MB objects by default. For
an EC pool, RADOS internally will further subdivide them based on the
erasure code and striping strategy, with a layout that can vary. But
by default if you have eg an 8+3 EC code, you'll end up with a bunch
of (4MB/8=)512KB objects within the OSD.
