Description steveh 1999-08-21 22:08:11 EDT
After installing dump-0.4b4-9.i386.rpm, my backup script
started failing, with a "DUMP: Please choose a blocksize <=
64KB" message, and a commandline that read:

/sbin/rdump 0ubdsf 126 62500 76800 poplar:/dev/rmt/0n /

Rolling back to dump-0.3-17.i386.rpm fixed the problem.

Solaris 2.6 Sparc 10 server onto an Exabyte 8mm tapedrive.

This a feature not a bug. There are few performance gains (and
possible losses!) with large block sizes due to max TCP window
sizes and/or physical DMA allocation.

Does dump-0.4b4 with 64K buffers run significantly slower than
dump-0.3 with 768K buffers to solaris server? Are you sure that
the blocksize and not some other factor that is the rate limiting

jbj is the dump guru.
