Hi Adam,
I configured this now but I am not sure how I could confirm if I have
the syntax correct.
I want vdsm to leave alone the VGs called ovirt and kvmvg.
lvm_dev_whitelist = [ "r|^/dev/kvmvg|", "r|^/dev/ovirt|" ]
I restarted vdsmd and did not get any error.
I also tried to write some bollocks to vdsm.conf, restarted and searched
for an error in vdsm.log. surprisingly that also seems to work !?!
so the general question actually is: how can i make sure that vdsm.conf
options are read correctly. where and when is this checked? what to look
for in vdsm.log (or even other log files?)
thanks
Jojo
