Hello, Had an interesting issue today. My OSD hosts are booting off a USB key which, you guessed it has a root partition on there. All OSDs are mounted. My USB key failed on one of my OSD hosts, leaving the data on OSDs inaccessible to the rest of my cluster. I have multiple monitors running other OSD hosts where data can be recovered to. However I’m wondering if there’s a way to “restore” / “rebuild” the ceph install that was on this host without having all OSDs resync again. Lesson learned = don’t use USB boot/root drives. However, now just looking at what needs to be done once the OS and Ceph packages are reinstalled. Thank you. _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
