linux client trying to use itself as server
In regard to: [Networker] linux client trying to use itself as server,...:
we have a problem with Postgres on linux doing backup with savepnpc.
OS is Redhat 5.7, networker version is 22.214.171.124.
Node is running a PostgresDB, backup goes with savepnpc. Pstclientsave
sends WAL-Logs from client to server. Sometimes (not very often) the
following messages appears in savepnpc.log:
3817:save: Using "clientname" as server
39076:save: RPC warning: RPC cannot make a procedure call: Create failed:
Program not registered
This could be any number of things. The suggestion you've already
received to verify the contents of /nsr/res/servers is a good one,
especially if there are any hosts on your network that you don't trust,
as having an empty servers file has security implications.
Since it manifests as an intermittent network problem, it could
potentially be on the client, on the intervening network gear, or on
The Installation guide for the server software and the "Technical Guidance
for Upgrades to EMC NetWorker" documents on powerlink have a number of
tuning suggestions for each NetWorker server platform. If you haven't
applied those suggestions, I highly recommend you investigate them.
Intermittent network issues could certainly happen if the server is
running short of some network-related resource.
After that it continues with
3817:save: Using "networker server" as server
and backup goes on.
One additional thing you could try is to modify the NetWorker client
properties so that the server passes "-s servername" to each save. You
can do this via the GUI by filling in the *server's* name (we use FQDN,
but your environment may differ) in the "server network interface" on the
"Globals (1 of 2)" tab for the client properties.
This may just mask the underlying problem, though.
Savesets on the server are complete, so it seems the saveset is sent again
with the right servername and saved on tape as it should be.
Are "Client retries" set to some positive value in the properties for the
group containing that client?
