This is 5.0.5 box.
I am trying to accumulate multiple files in a single tar file.
Files are added daily, so I would need to add them to tar file,
uniqness of the file names is guarantied.

Here is simple example showing the problem I am running into:


$ tar ncvf A x*
seek = 0K a x1 548K
seek = 548K a x2 252K

$ tar nuvf A y*
tar: buffer size = 10K
seek = 800K a y1 594K
seek = 1395K a y2 594K
seek = 1989K a y3 594K

$ tar tvf A
tar: blocksize = 20
rw-rw-r--243/50 560131 Dec 18 13:29 2002 x1
rw-rw-r--243/50 257334 Dec 18 14:55 2002 x2
tar: directory checksum error

$ l
total 10374
-rw-rw-r-- 1 haa group 2637824 Apr 12 18:22 A
-rw-rw-r-- 1 haa group 560131 Dec 18 2002 x1
-rw-rw-r-- 1 haa group 257334 Dec 18 2002 x2
-rw-rw-r-- 1 haa group 608255 Dec 18 2002 y1
-rw-rw-r-- 1 haa group 608226 Dec 18 2002 y2
-rw-rw-r-- 1 haa group 607769 Dec 18 2002 y3

I tried tar "r" instead of "u" with the same outcome: resulting in a
tar file with directory checksum error.

Any ideas how to do it properly will be appreciated,
Regards,
Michael.

I tried what you have on 5.0.6 and it does as expected. Try the reverse
order. Perhaps there is a problem with the file x2 or y1.

Well, I tried many different files, and those are just plain ascii
text data, I do not have control in which sequence files are coming -
I need to add them to tar archive, and this tar:

$ type tar
tar is /usr/bin/tar
$ ls -l /usr/bin/tar
lrwxrwxrwx 1 root root 35 Nov 10 1999 /usr/bin/tar ->
/opt/K/SCO
/Unix/5.0.5Eb/usr/bin/tar

seem to not working, or I do not understand the syntax?
In fact, I just ran the same sequence of commands (tar ncf ..., then
tar nuf ... ) on 5.0.7 box and got same problem.
Any help will be appreciated,
Michael.

Interesting. I tried it here (also OSR 5.0.5) and had the same problem.
I'd never noticed that before, but I don't usually add files to a tar
archive. I don't have a solution for you. I partly just wanted to confirm
the problem, although I do have a couple of things to add.

I tried adding a block size to the tar commands. No effect.

I noticed that if I ran the tar commands again when a "bad" archive
existed, the new archive was OK. IOW, I run the commands you gave and
create an archive called A. "tar tvf A" gives the directory checksum
error. I leave A and run the same tar commands again and this time "tar
tvf A" lists the complete archive with no errors. Delete A and run the
commands again and I get the error again. Run the commands again without
deleting A first and I get a good archive again. Very odd. I tried
creating A first, but putting other files in it, and then running your
commands and I got the error again. It was only when I created A from
those same files and then ran your commands that I didn't get the error.
But I don't know if that was due to the specific content or something else,
like the overall size of the file.

What size files did you try? I first tried it with some small files (the
largest was probably around 14 KB and most were much smaller) and got no
error. But when I tried it with some larger files (the total size of the 5
files was a little over 2 MB), I got the same error he did.

One other thing. If all else fails, you could give gtar (GNU tar) a try.
The version I have seemed to work OK doing the same commands. Note that
gtar, at least the version I have, doesn't support the "n" ("not a tape
device") option and I couldn't find a similar option, but it doesn't seem
to need it.

I'm not sure where I got gtar, but it was probably from ftp.sco.com, which
could be a problem since the server seems to be in a state of flux right
now. I imagine you can find it somewhere else on the 'Net. Or I could
email you a copy of the gtar installation file I have. If nothing else,
there seems to be a gtar executable (with no documentation, etc.) at
ftp://stage.caldera.com/skunkware/osr5/bin/gtar .

damn, and I thought it was just me.
I tried to use that feature for the first time a couple weeks ago on a 5.0.6
box and it would work a few times and then fail, no pattern other than it
never made it to 10 appendings. The files were tiny, 80 or 160 bytes of
plain text.

I'm trying to keep copies of little edi files that are generated every few
minutes all day long so that we can track failures better and prove whether
the data was created properly, whether the ftp suceeded (proven by
downloading the file after uploading and "cmp"ing the original and
downloaded) etc...

I gave up and switched to just using a temp file naming scheme that includes
the date & time and I just don't delete any files all day long, then the
first time the script runs after the date changes, it notices that there are
files with names that don't match todays date, and tars up all of yesterdays
files before proceeding with the current task.

This ends up actually being more convenient as a bonus because now all
during the day my less well-rounded coworkers have easier ready access to
the recent files since all of todays files are sitting there in a directory
in plain text ready to less or vi
(I used to think the users were the biggest babies but try to tell a
programmer how to list a tar and extract one file or extract all files but
in a safe directory, and don't even think about injecting a compressor into
that conversation...)

Per J James suggestion I tried gnu tar and it worked just fine.
I wonder if the problem with SCO's version of tar is well-known?
Is there a workaround?

Michael.

I also tried this on two directories containing large files and it presented
no problem. Apparently the problem is fixed on 5.0.6. Maybe there is a
patch for 5.0.5 I wonder if the executable from 5.0.6 will run on 5.0.5???

Ran into a similar issue with 5.0.2 IFRC. A script would add email
to a tar archive, EDI sessions in reality, that we wanted to keep
track of. Everything worked perfectly for a while, email would
accumulate in the mail file, then would be copied to a unique file
and added to the tar archive before the application read it. To
my surprise I found the archive unreadable after a while. Many
attempts to debug the issue resulted in random failures. I reported
the issue to SCO, who were unable to duplicate the problem.

When you have a bad tar archive, scan through it with "hd" to the
failure location ( which you can determine from the file sizes ).
Do you see some FF or 00 bytes?
