Re: Linux Client Won't Back Up

2003-07-09 Thread Richard Sims
If I back up files individually, it works OK.  But when I try to do an
incremental back up of a file system, I get the following errors:

ANS1005E TCP/IP read error on socket = 8, errno = 104, reason : 'Connection
reset by peer'.

The peer is the TSM server.  What does its Activity Log say about the reason
that it terminated the session?  Maybe the server was installed with default
configuration values and its timeout specs need boosting?

Thanks for your response Richard,

The activity log says:

ANR0481W Session 3174 for node GPGECOS (Linux86) terminated - client did
not respond within 60 seconds.

The TSM server has:
  IDLETIMEOUT   30
  COMMTIMEOUT  60

Other nodes compress and transfer files over a gig in size.  With this
Linux node, I can't even get /var, with several little files, to back up.

I wonder if there's some problems with the TCP/IP settings in Linux
itself not necessarily TSM.

The server COMMTimeout is way, way too low for reality.  A value of 3600
is much more realistic.  Boost it via the SETOPT command (then manually
fix the dsmserv.opt file for the next restart.)

It's not the size of the file: it's the amount of time in between files.
You need to give the client time to rummage around in its file system to
accumulate the next buffer's worth of files and send that, which can take
considerable time in an Incremental with a file system that has few updates.
