Package: rrdtool Version: 1.7.2-3+b4 Severity: normal joey@darkstar:~> rrdtool create foo.rrd DS:foo:GAUGE:1:10:1000 RRA:AVERAGE:0.5:1:864000 joey@darkstar:~> rrdtool update foo.rrd N:100 joey@darkstar:~> rrdtool tune foo.rrd DS:xxx ERROR: invalid DS format - exit 1
That tune looks like it would have failed to do anything, but in fact
it's added a weird DS to the file.
So now updates will fail:
joey@darkstar:~> rrdtool update foo.rrd N:100
ERROR: foo.rrd: expected 2 data source readings (got 1) from N
- exit 1
joey@darkstar:~> rrdtool update foo.rrd N:100:1
ERROR: unknown data acquisition function '0'
rrdtool dump shows that it added a DS with an empty name and bogus type.
<ds>
<name> </name>
<type> 0 </type>
<minimal_heartbeat>0</minimal_heartbeat>
<min>0.0002525175e-308</min>
<max>0.0001931016e-308</max>
<!-- PDP Status -->
<last_ds>1</last_ds>
<value>0.0000000000e+00</value>
<unknown_sec> 194 </unknown_sec>
</ds>
The empty name also makes it hard to delete it, because "DEL:" will not
refer to it. The only way I found to recover my data was to edit the xml
dump, putting in a name, and then load and delete it.
