问为什么logrotate什么都不做，却不抱怨错误？

Handling 1 logs

rotating pattern: /mnt/nginx/logs/access.log  forced from command line (10 rotations)
empty log files are not rotated, old logs are removed
considering log /mnt/nginx/logs/access.log
  log needs rotating
rotating log /mnt/nginx/logs/access.log, log->rotateCount is 10
dateext suffix '-20140724'
glob pattern '-[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]'
glob finding logs to compress failed
glob finding old rotated logs failed
renaming /mnt/nginx/logs/access.log to /mnt/nginx/logs/access.log-20140724
creating new /mnt/nginx/logs/access.log mode = 0640 uid = 0 gid = 0
running postrotate script
