do not have gaps in device ids

Just took a look at my syslog.... just meant as information for others 
that might run into the same troubles

It got spammed by those messages:

device 7 is not in DB, nor is any file ( _* table) linked to this device.
device 7 was a spare hd (/dev/hdc1) with data on it ... i planned to 
insert it into mogile after i inserted the data on it into mogilefs 
(turned out to be a defect harddisk anyway)
(after assembling the computer it was hdc on the second comp in cluster 
so it was meant to be dev7)

but back to the errors:
after i added dev7 as dead device to host 2 all worked fine and no 
errors anymore.

another wired problem is that file_to_replicate had strange values.
it contained 90 rows with a nexttry value of 2147483647 (translates to 
Tuesday, January 19th 2038, 3:14:07 (GMT)).

No idea where that came from either.
after i changed nexttry to 0 the table got cleaned up.
(all files that were in there were already replicated often enough and 
so mogilefs just deleted that rows out of the db, guess that were tries 
to replicate to dev7 that never existed)


device 7 is still a noshow (though visible in db as dead device):
