Thank you!
Not sure why the debug file would list runtar in the form of a parameter, when it's not to be used
as such. Anyway, that got it working.
Which brings me back to my original problem. As indicated previously, the filesystem in question
only has 2806 files and 140 directories. As I watch the runtar in verbose mode, when it hits the tif
files, it is taking 20 seconds on each tif file. The tif files are scans of herbarium type specimens
and are pretty uniformly 200MB each. If I do a find on all the tif files, piped to `wc -l`, there
are 1300 of them. Times 20 seconds each gives me the 26000 seconds that shows up in the sendsize
debug file for this filesystem.
So, why would these tif files only be going by at 10MB/s into /dev/null? No compression involved. My
(real) tapes run much faster than that. I also pointed out that I have more than a dozen other
filesystems on the same zpool that are giving me no trouble (five 2TB drives in a raidz1 on a J4500
with multipath SAS).
Any ideas how to speed that up?
I think I may start out by breaking them down into sub DLE's. There are 129 directories
corresponding to taxonomic families.

I may just quietly go nuts. I'm trying to run the command directly. In the debug file, one
example is:
Mon Apr 1 08:05:49 2013: thd-32a58: sendsize: Spawning "/usr/local/libexec/amanda/runtar runtar
daily /usr/local/etc/amanda/tools/gtar --create --file /dev/null --numeric-owner --directory
/export/herbarium --one-file-system --listed-incremental
/usr/local/var/amanda/gnutar-lists/localhost_export_herbarium_1.new --sparse --ignore-failed-read
--totals ." in pipeline
So, I created a script working off that and adding verbose:
#!/bin/ksh
OPTIONS=" --create --file /dev/null --numeric-owner --directory
/export/herbarium
--one-file-system --listed-incremental";
OPTIONS="${OPTIONS}
/usr/local/var/amanda/gnutar-lists/localhost_export_herbarium_1.new --sparse
--ignore-failed-read --totals --verbose .";
COMMAND="/usr/local/libexec/amanda/runtar runtar daily /usr/local/etc/amanda/tools/gtar
${OPTIONS}";
#COMMAND="/usr/sfw/bin/gtar ${OPTIONS}";
remove the 'runtar' argument
exec ${COMMAND};
If I run that as user amanda, I get:
runtar: Can only be used to create tar archives
If I exchange the two commands so that I'm using gtar directly rather than
runtar, then I get:
/usr/sfw/bin/gtar: Cowardly refusing to create an empty archive
Try `/usr/sfw/bin/gtar --help' or `/usr/sfw/bin/gtar --usage' for more
information.
