Hi Shain, As long as you don’t nuke the OSDs or the journals, you should be OK. I think the keyring and such are typically stored on the OSD itself. If you have lost track of what physical device maps to what OSD, you can always mount the OSDs in a temporary spot and cat the “whoami” file. —Lincoln > On Mar 10, 2017, at 11:33 AM, Shain Miley <SMiley@xxxxxxx> wrote: > > Hello, > > We had an issue with one of our Dell 720xd servers and now the raid card cannot seem to boot from the Ubuntu OS drive volume. > > I would like to know...if I reload the OS...is there an easy way to get the 12 OSD's disks back into the cluster without just having to remove them from the cluster, wipe the drives and then re-add them? > > Right now I have the 'noout' and 'nodown' flags set on the cluster so there has been no data movement yet as a result of this node being down. > > Thanks in advance for any help. > > Shain > > > -- > NPR | Shain Miley | Manager of Infrastructure, Digital Media | smiley@xxxxxxx | 202.513.3649 > > _______________________________________________ > ceph-users mailing list > ceph-users@xxxxxxxxxxxxxx > http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
