HELP gzip

[Jason Berendsen]

I am trying to decompress a gzip file and it blows up at 2 gigs with the following error:
File too large

I checked my filesystem and it is set to largefiles.

I downloaded gzip version 1.3.1 after finding that this was a problem with 1.2.4. Even running with version 1.3.1 I am still getting this error.

What is causing this????

Did you get it from the hpux porting site? That depot was built to handle the >2GB files. If so run gzip -V and see what version it tells you that you are using. We can go from there.

Are you sure you are using the new version of gzip since installing version 1.3.1? The gzip that comes with HP-UX is in /usr/contrib/bin, but when you install a new version of gzip it is installed /opt/gzip/bin.

It still sounds like either gzip, or your filesystem are problems. Double check and make sure that your LV can support large files.

# fsadm /mount_dir

And do the gunzip by specifying the new gzip explicitly:

# /opt/gzip/bin/gunzip file_to_gunzip.gz

The following is the output of my filesystem:
root@unixadm1:/opt/gzip/bin > fsadm /testing
fsadm: /etc/default/fs is used for determining the file system type
nomultifsets
largefiles

The command I am running to decompress is /opt/gzip/bin/gzip -d /testing/mermod02.gz

This may be a silly question, but since you are specifying the fully qualified file name, what directory are you in when executing the gunzip operation?

Have you tried:

# cd /testing
# /opt/gzip/bin/gunzip mermod02.gz

Craig,

Where is the porting site? I did a search for gzip at software.hp.com and came up empty. I am running gzip 1.2.4 and would like to upgrade.

Thanks,

This is the URL that I got the newer version from.

Patrick,

I tried as you suggested by changing directory to testing first. That worked. Why doesn't it work when I fully qualify the path?

[Mark Greene_1]

Jason,

thanks for the URL, give yourself 10 points. :-)

The only reason I can think of for it not working when you specified the full path was that it was using your CURRENT directory as a kind of working directory, before moving the gunzip'ed file back to its original location. If you were in /opt, /opt by default does NOT support largefiles, when gunzip'ing the file and the file reached 2GB, then you would probably see the error.
