Upgrading to 7.0 from anything before will increase disk usage of RRDs by a factor of up to nearly 10. In practice, we've seen much smaller overall disk increase factors. The reported disk increase factor With a customer was 127 / 57 = 2.28 (i.e.we are using 2.28 times more disk now; that's a (127 - 57) / 57 * 100 = 122.8 percent increase.We can get the disk space used by (AW)RRD files via:du -sh /var/airwave/rrdThat is probably a significant portion of the 117 GB (127 GB - the 10 GB for postgres data).If it isn't, then we have to go looking for disk usage by other possible candidates.This command will show us disk usage of things in the current directory (files and directories' cumulative usage) sorted with the largest disk space users at the bottom:du -sk * | sort -nWe can "zoom in" to find the large file. Eg. Start in /var and run that:[root@henry var]# du -sk * | sort -n...1736 spool66056 www849508 cache2952196 lib6263832 airwave-backup8689352 log12069528 airwaveSo /var/log is using 8.6 GB (on my dev amp) but /var/airwave is using 12 GB. How is that 12 GB split up?[root@henry var]# cd airwave[root@henry airwave]# du -sk * | sort -n ...41432 VisualRFdiagnostic.tar43072 html_snapshot55284 sites159468 graphs299240 cache347296 data11081432 rrdIt's almost all rrd data (11 GB worth).Postgres data, of course, is under /var/lib/pgsql:[root@henry airwave]# cd /var/lib/pgsql/[root@henry pgsql]# du -sk * | sort -n8 pgstartup.log1869308 dataAnd is taking up 1.8 GB on the Lab amp.
