Description Ben Marzinski 2005-03-16 17:19:10 EST
If gulm or cmam use anything other than the value of uname -n for the cluster
nodename, gnbd will be using the wrong name.  This means that gnbd will not be
able to correctly fence the server. Also, unless the nodename parameter for
fence_gnbd is equal to uname -n, fence_gnbd will return false successes, allowing
corruption to occur.
Comment 1 Ben Marzinski 2005-03-16 17:43:57 EST
I changed the default behaviour of gnbd to get the nodename from magma.  If gnbd
is being used for some non-clustered purpose, the magma check can be overriden by
using the -n option to gnbd_import or gnbd_serv.  When -n is used, gnbd will
simply use uname -n.
