Re: strange output from storage promise

All,

after adding the default body mentioned by Bas van der Vlies, everything 
works as expected...

root@wpsap: /root # /var/cfengine/bin/cf-agent -KI -b rootvg_diskspace
    info: Using command line specified bundlesequence
    info: Filesystem '/var' content seems to be sensible as promised
    info: Filesystem '/opt' content seems to be sensible as promised
    info: Filesystem '/' content seems to be sensible as promised
    info: Filesystem '/usr' content seems to be sensible as promised
    info: Filesystem '/tmp' content seems to be sensible as promised

here the requested df output:

root@wpsap: /root # df /opt/
Filesystem    512-blocks      Free %Used    Iused %Iused Mounted on
/dev/hd10opt    11534336   7785720   33%    45681     5% /opt

thank you all for helping me out...

cheers

chris
