Re: Unable to restart Mon after reboot

[Dan Mick <dan.mick@inktank.com>]

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).
