Try:

    pg_dumpall | gzip >dumpfile

pg_dump and hence pg_dumpall also has compression option flags.

I think ext2 can't support file larger then 2G,
and your DB may be near 5Gb, so it's a problem.
take a look at:

http://www.postgresql.org/idocs/index.php?backup.html#BACKUP-DUMP-LARGE

or change to some journal filesystem like reiserfs would help.

I think the problem here is in kernel 2.4.17 ..
I had a problem with 2.4.11 kernel when i tried
to mke2fs a partition > 2 Gb in size ... mke2fs died with a message:
"file size exceeded" ...  The solution was to log in directly with
root ...

The problem lies in bash ulimits, AFAIR
