If you change that dumptype to "index no" does the backup work? I
can't remember if what you are seeing is the exact failure we had, but the
cause was that with indexing turned on, the restore command was closing it's
input and causing the whole pipe to fail. That is, sendbackup executes
something like:
dump {options}f - /{netapp}/{path} | tee {dumpfile} | restore -tvf - 2>&1 |
sed {stuff} > {index file}
Which because of the wrapper around dump really looks like:
rsh {netapp} dump {options}f - {path} | tee...
Since dump sends the file list before the files, the restore process
(with "t") is done long before dump if the filesystem is sufficiently large.
For some reason, when the restore command blocks input, the filer dump
command aborts and causes the dump to fail. If this is the problem you are
having, you should be able to duplicate a failure simply by doing something
like:
rsh {netapp} dump 0f - {path} | restore -tvf - 2>&1 > /dev/null
We fixed it by writing a wrapper around restore that detects when
the restore command downstreams blocks and then continues to accept input
(the actual dump contents) but simply throws it away.
