logrotate and auto start = no

[Wido den Hollander <wido@widodh.nl>]

Hi,

When "auto start = no" is set for the OSD's, the logs won't get rotated.

I've set this to no so I can easily reboot machines without all OSD's 
starting, I think it's easier with testing or when you replace a broken 
disk.

Anyway, this prevents the logs from being rotated, causing my disks to 
fill up:

/var/log/ceph/*.log {
     rotate 7
     daily
     compress
     sharedscripts
     postrotate
         invoke-rc.d ceph reload >/dev/null || service ceph reload 
 >/dev/null
     endscript
     missingok
}

The init script doesn't touch daemons which have auto start set to no, 
but this also prevents logrotate from doing it's job.

Some suggestions:

1. Don't use the init script for logrotation
2. Modify the init script
3. Add a note in the documentation about this behaviour

I think that logrotation should work regardless the setting of auto start?

What do you think?
