linux - How to force (or workaround) logrotate to move old logs to olddir on different physical disk? -

i want logrotate copy , truncate log file , use olddir on different physical disk. according manual, olddir can't on different physical disk because default behaviour of logrotate rename original log file, wouldn't possible different physical disk.

well, using copytruncate directive, makes copy of original file , truncates original file. there shouldn't problem moving newly copied file different location on different physical disk.

but when run logrotate, still complains logfile , olddir beeing on different devices.

is there way around ? possibly running custom postrotate script move log files desired location ?

this logrotate man page.

  olddir directory <br>         logs  moved directory rotation. **the directory must on          same physical device log file being rotated**, , assumed           relative    directory holding log file unless absolute path          name specified. when option used old versions of   log          end   in  directory.    option  may overridden noolddir          option. 

existence of olddir on same physical device limitation.

one can use below workaround.

set olddir directory in same physical disk, , use postrotate script move contents of olddir directory on different physical device.

example logrotate configuration file:

/var/log/httpd/*log {         copytruncate         olddir /var/log/httpd/olddir         rotate 5     missingok     notifempty     sharedscripts     delaycompress     postrotate         mv /var/log/httpd/olddir/* /vagrant/httpd/olddir/         /sbin/service httpd reload > /dev/null 2>/dev/null || true     endscript }
