I've posted the information below twice to the admin list without getting a
solution, so I'm promoting it to a bug.
I'm not subscribed to the bug list, so please cc me on responses and I'll
try to supply information as needed.
I'm getting the following error message:
pg_dump: [tar archiver] could not write to tar member (wrote 39, attempted
166)
Here are the particulars:
-I'm running this command: "pg_dump -Ft prod > prod.dump.tar" (The database
is named prod)
-The dump gets about 1/4 of the way through, and then gives me the error
message and dies.
-I'm running PostgreSQL version 7.3.2.
-There is plenty of disk space available.
-The same command on the same database and server with same specs worked
last week when I was on V7.2.1.
-Since upgrading, more data has been added, but the structure of the
database is unchanged.
-Using the -v switch shows me that it always quits on the same table, but
otherwise adds no new information.
-The part of the error message in parentheses changes on each run. For
instance, on the last run, I got "(wrote 64, attempted 174)" The rest of
the message remains consistent.
-The table it quits on is fairly large- about 2.6GB. It is both "wide"
because it contains a text field that is usually a few sentences of text,
and "long", containing 9,137,808 records. This is also the only table in our
database that is split into multiple files.
-A text dump using this command works fine and exports the entire database
without a problem: "pg_dump prod > prod.dump.text"
-I have set up an identical system (Same hardware, same software, same Data
in DB) to do testing on, and confirmed that I get the same error on this
system, so it appears to not be a hardware error or just a bad copy of the
software.
-Several folks suggested that I was hitting the 2GB file size limit. This is
not the case. Here is a snip from the console log on the second machine that
I'm using to diagnose with:
nickf@morgai:~$ pg_dump -Ft alpha > dump.tar
pg_dump: [tar archiver] could not write to tar member (wrote 110, attempted
398)
nickf@morgai:~$
nickf@morgai:~$
nickf@morgai:~$ ls -al dump.tar
-rw-r--r-- 1 nickf nickf 1388367872 Jul 21 14:49 dump.tar
nickf@morgai:~$
Thanks for looking this over- please let me know if anyone has any ideas
about this.
-Regards,
-Nick
