[ncr.sys.unix] Interesting TAR problem

murray@npdiss1.StPaul.NCR.COM (Michael C. Murray) (06/03/91)

Anyone seen this somewhat interesting "tar" problem?

Here's the situation:  I have a backup created w/ command

	tar cvfbk <floppy dev 0> 10 1200 <filespec>

onto 1.2M 5.25" floppy. The backup has 10 volumes (9 extents). When I 
attempt to restore the archive onto a different system w/"tar xvf", it 
reads the first volume, prompts for insertion of the second, and gets
partway through before displaying

	"tar: <filename>: HELP - extract write error"
which of course kills the restore.

There are two interesting "symptoms":

	1) It always bombs after writing 2097152 bytes of the file.
	2) It bombs at the "2097152 point" regardless of the extent
	I begin the restore from. So for instance if I begin w/extent #2
	it writes out all of extent #2, prompts for the next one, writes
	a portion and then dies (at 2097152 bytes).

Does this sound like a ulimit problem?  I don't have access to the machine for
a few days so I can't verify.  Suggestions?

Thanks.

Read the FAQ (specifically the question about ULIMIT).
