I'm migrating Cacti from Windows to Linux and I've come across a bit of a problem.
The Windows server is running an older version of Cacti so I'm migrating it to version 0.8.
I've managed to port the database across to the new server, the installer ran successfully and the tables have been migrated to the new version. I've copied over the RRA folder (containing the old RRD files) from the Windows server to the new version on the Linux server but graphs are not displaying.
Manually running poll.php from the command line reveals this error when Cacti tries to update the RRD files:
ERROR: reached EOF while loading header rrd->ds_def
Any ideas what might be causing this?
Thanks in advance!
