Should I infer from the silence that there is no way to recover from the
"FAILED assert(last_e.version.version < e.version.version)" errors?
Thanks,
Jeff

Some additional information/questions:
Here is the output of "ceph osd tree"
Some of the "down" OSD's are actually running, but are "down". For example
osd.1:
root 30158 8.6 12.7 1542860 781288 ? Ssl 07:47 4:40
/usr/bin/ceph-osd --cluster=ceph -i 0 -f
Is there any way to get the cluster to recognize them as being up? osd-1 has
the "FAILED assert(last_e.version.version < e.version.version)" errors.
Thanks,
Jeff
