The problem seems to be related to the number of entries in the disklist for the relevant host. I originally had <hostname> wd0a user-tar -1 <hostname> wd0e comp-user-tar -1 <hostname> wd0g comp-user-tar -1 <hostname> /var/amanda user-tar -1 <hostname> /var/backups user-tar -1 <hostname> /var/clamav user-tar -1 <hostname> /var/cron user-tar -1 <hostname> /var/mysql user-tar -1 <hostname> /var/named user-tar -1 <hostname> /var/spool comp-user-tar -1 <hostname> /var/www user-tar -1 (I've replaced the real, fqdn, hostname for security reasons). After some considerable amount of cut-and-try testing I discovered that the system worked quite happily with just one disklist entry. Further testing revealed that it was quite happy with as many as 7 entries, more would cause the first few to fail, and the whole set would cause the lot to fail. Replacing the above with one entry per filesystem (i.e wd0a, wd0e, wd0g) where the whole filesystem was needed, and the top level directory (/var) for the other case, with an exclude file to eliminate the unwanted had the whole set dumping correctly. I have no idea if this is a generic Amanda issue or one specific to the OpenBSD port. Debugging was complicated by the disk entries being tried in reverse order, something else that does not seem to be mentioned in the documentation. In case anyone wonders about the effect of 'inparrallel' I left it at the default of 4.
