: Re: [ceph-users] Ceph Write process
Thanks Loris,
So after client receiving ACK, if client makes a read request to this object
immediately , does it have to wait for object written to file store, or read
directly from journal?

Hi Cephers,
When an Ceph write made, does it write to all File Stores of Primary OSD
and Secondary OSD before sending ACK to client, or it writes to journal of
OSD and sending ACK without writing to File Store?
I think it would write to journal of all OSD, so using SSD journal will
increase write
