Hi,
I am wondering what the lvm_dev_whitelist vdsm.conf option is for?
I had some issues whith vdsm switching off logical volumes that it
better should keep it's hands off.
Could this option help to handle this?
Yes this option should be exactly what you are looking for. You
specify a comma separated list of glob expressions and vdsm will
instruct lvm to ignore all devices which are not matched by your list.
See:
https://www.centos.org/docs/5/html/Cluster_Logical_Volume_Manager/lvm_filters.html
for more background information on the LVM filters.
perfect, I will try this out.
thanks a lot for your answer.
all the best

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
