Now sde fails and is replaced with a new drive. Where do you put the journal for the new sde?

If I rm partition 1 before running ceph-disk, it seems to re-use partition 1 but the udev triggers (probably partx) don?t quite like this and the osd is never activated. > > I?m just curious, for such a routine operation, what are most admins doing in this case? > I simply would do: $ ceph-deploy osd create mycephnode1:sde:sda1 That should work just fine. > Cheers, Dan > > _______________________________________________ > ceph-users mailing list > ceph-users at lists.ceph.com > http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com > -- Wido den Hollander 42on B.V.
