I have found a solution: ceph-osd --get-journal-fsid --osd-journal=<partition> -i 0 Note: the "-i 0" is required by the command line, but makes no difference in the output - i.e. '-i 2' works just as well. This results in an fsid which matches the fsid of the OSD it belongs to. :) On Thu, Apr 25, 2013 at 11:05 AM, Gregory Farnum <greg@xxxxxxxxxxx> wrote: > On Wed, Apr 24, 2013 at 6:05 PM, Mandell Degerness > <mandell@xxxxxxxxxxxxxxx> wrote: >> Given a partition, is there a command which can be run to validate if >> the partition is used as a journal of an OSD and, if so, what OSD it >> belongs to? > > The new-style deployment stuff sets partition type GUIDs to special > values that end in values like ceff2be and ceff05d so I think you can > check for those to see if it's a journal or not (if using ceph-deploy > or another tool chain that involves ceph-disk-[prepare|activate]). > There's nothing that encodes which OSD it belongs to that's > user-accessible right now, though. :/ You should make a feature > request! > -Greg > Software Engineer #42 @ http://inktank.com | http://ceph.com _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
