[Linux-cluster] EXT3 service mounted on two nodes

[Josh Gray]

Hello Lon & the rest of the list -  You responded the other day that my
problem with the ext3 volume mounting up on multiple nodes might be related
to this bug listed.

Support looked over my config and explained to me that I nested my resources
when I really shouldn't have.   They say the cluster reads the order in
reverse so If I made the parent the filesystem, then the nfsexport, then the
nfs clients, then the ips in that order - they say this is why I saw a brief
error that the path the nfs client was given access to doesn't exist -
though everything would start up fine eventually.      They say I should do
them all on the same level, and it'll work fine, indeed it does seem to work
great.  

Is it possible the cluster got confused when it was trying to start these
services this one time and just by chance mounted the filesystem and brought
up the VIP's on both nodes BECAUSE of this and not the bug?

I guess what I'm getting at is - should I feel more comfortable with this
one problem solved?
