[gpfsug-discuss] tar sparse file data loss

[Knister, Aaron S. (GSFC-606.2)[COMPUTER SCIENCE CORP]]

Somehow this nugget of joy (that’s most definitely sarcasm, this really sucks) slipped past my radar:

Anyone know if there’s a fix in the 4.1 stream?

In my opinion this is 100% a tar bug as the APAR suggests but GPFS has implemented a workaround. See this post from the tar mailing list:

https://www.mail-archive.com/bug-tar@gnu.org/msg04209.html

It looks like the troublesome code may still exist upstream:

http://git.savannah.gnu.org/cgit/tar.git/tree/src/sparse.c#n273

No better way to ensure you’ll hit a problem than to assume you won’t :)
