If you ask the team here what our Number One NetWorker Problem is,

it. We experience hung savegroups every day, mostly in our larger

savegroup
just before it is scheduled to run.
I suppose that this same solution could be incorporated into the
product if Legato desired. The current behaviour is that a group
will fail if the same group is already running, and of course it
does give you a notification when this occurs, however it could be
possible to add a switch in the group resource that would give the
option to kill an already running group before starting another
instance. This is exactly what my script does, although it's not as
neat as having it built into the product.
Interestingly, on some occasions, issuing the kill command to the
client's
nsrexec process causes the group to end successfully. Go figure!
Well yes, this is what I would expect. If the server's nsrexec
connection to the client is broken, then that save set can complete
(most likely unsuccessfully), so the work list can clear down and
the group will finish.
We have been discussing this with a NetWorker Product Manager.
I'll post
anything I learn to the list.
What do you expect as a result from this? What kind of solution can
you envisage? Also I'll be willing to bet that the hung clients are
Windows machines in the majority of cases. Am I right?
In my NetWorker environment, Windows servers account for maybe 99% of
the issues I see with never ending savegroups. I do see this happen
once in a while with clients that Red Hat Linux, but its rare. I
suspect part of this issue is inefficient tcp settings on the clients
in question, but I am not in a position to suggest any better settings.
