This was seen when attempting to do profiling on
The opcontrol command does the following:
mount -t oprofilefs nodev /dev/oprofile >/dev/null
Since this adds the entry to /etc/mtab, a subsequent
node can't do another mount even though /dev is unique
for each node.
While we could simply add a "-n" to the opcontrol
script, this doesn't solve the general problem. We
could change the mount command to replace /dev
directory specification to /cluster/nodeX/dev. This
would allow every node to mount below /dev, because the
mount command would fix things to reflect the SSI
kernel notion of what /dev is.
I believe that this change would improve our
