Subject: location-aware file placement in Ceph
Date: Thu, 27 Feb 2014 14:25:00 +0100 [thread overview]
Message-ID: <530F3CAC.2040504@gmail.com> (raw)
Dear all,
As new to ceph, may I ask in the crush algorithm, is there a way to
configure where the file to be stored, not randomly.
My requirement is to place the files that within the same
location(within a geographic area), into the same OSD, instead of
randomly placing them seperately.
I guess crush may support this. But to do this, I just have to configure
some parameters in some ceph commands? or I have to modify the ceph
crush algorithm and re-compile ceph?
Many thanks for any helpful pointers.
Cheers, Giovanni
