I had a very old server on a 32 bits platform. A few days ago, I bought a new one with a 64bits platform.
\nI was using Smokeping on this server, and I wanted to keep my old data. If you copy .rrd files in place, you’ll get an error :<\/p>\n
This RRD was created on another architecture<\/pre>\nThat’s because RRD file structure changed based on the architecture you have. Yes, that’s silly but this is the way it is.<\/p>\n
To convert files, you have to dump data to an XML file, sync it on the new server, and reimport it.
\nThis is how to make it with justa few lines of bash :<\/p>\ncd \/path\/to\/rrd\/files;\r\nfor i in $(find . -name '*.rrd'); do rrdtool dump $i > $i.xml ; done\r\nrsync -av . my.server.ip:\/path\/to\/new\/dir\/rrd\/<\/pre>\nAnd on the new server :<\/p>\n
cd \/path\/to\/new\/dir\/rrd\r\nfor i in `find . -name '*.xml'`; do rrdtool restore --force-overwrite $i `echo $i |sed s\/.xml\/\/g`; done<\/pre>\n<\/p>\n","protected":false},"excerpt":{"rendered":"
