Hi Someone here will probably lay out a detailed answer but to get you started,
All the details for the osd are in the xfs partitions, mirror a new USB key and change ip etc and you should be able to recover. If the journal is linked to a /dev/sdx, make sure it's in the same spot as it was before.. All the best of luck /Josef On 25 Dec 2015 05:39, "deeepdish" <deeepd...@gmail.com> wrote: > 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.
