Hi, Every time I try an bring up an OSD, it crashes and I get the following: "error (121) Remote I/O error not handled on operation 20" The cluster is new and only has a little bit of data on it. Any ideas what is going on? Does Remote I/O mean a network error? Full log below: -9> 2013-01-10 00:00:20.182237 7f2ddde8f910 0 filestore(/mnt/dist_j/ceph) error (121) Remote I/O error not handled on operation 20 (12.0.0, or op 0, counting from 0) -8> 2013-01-10
