Hi David:
The code there is trying to read some stuff off the monitor's storage to
initialize, and apparently failing in an odd way. It's trying to read
the file 'latest' from the monitor directory (/data/mon0); the file can
be opened, and stat says it's 4289 bytes long, but apparently the read
is succeeding without error, but only getting back 0 bytes (i.e., not an
error, but apparently end of file).
See if there's a file /data/mon0/latest of length 4289, and see if
something is odd about its permissions (like maybe the read bits are
turned off, or maybe the filesystem it's on has errors).

Hi all,
I am testing Ceph 0.47.2 on btrfs with three servers running Fedora 17. Following a reboot of the servers, one of the mon daemons crashes on startup with "FAILED assert(r>0)"
MDS and the OSD start and run fine as do the mon daemons on the other two servers.
The debug log is at http://pastebin.com/tXwvd44Z
I would really appreciate any comments - especially if I am missing something obvious.
