Russell,
I've seen this years ago on some NetApp files. I've seen it more recently on
Hitachi storage too. I was able to work around the issue by changing the
following in /opt/xcat/share/lib/perl/xCAT_plugin/packimage.pm:
[root@gdcgmgtlgmt01 xCAT_plugin]# diff packimage.pm packimage.pm.orig
242c242
< $excludestr = "find . |cpio -o | gzip -c - > ../rootimg.gz";
---
> $excludestr = "find . |cpio -H newc -o | gzip -c - >
> ../rootimg.gz";
249c249,250
< $excludestr = "cat /tmp/xcat_packimg.txt|cpio -o | gzip -c - >
../rootimg.gz";
---
> #$excludestr =~ s!-a \z!|cpio -H newc -o | gzip -c - >
> ../rootimg.gz!;
> $excludestr = "cat /tmp/xcat_packimg.txt|cpio -H newc -o | gzip
> -c - > ../rootimg.gz";
I've also found other "issues" with using CPIO. Most recently I had an issue
where during the packimage CPIO itself was cross-linking hardlinked files (if
memory serves it was linking /bin/gzip, /bin/gunzip, /bin/zcat all to some file
in /usr/share/zoneinfo)....
With all of these issues I'm starting to look at not using CPIO but using
something like squashfs instead.....

Subject: [xcat-user] xCAT 2.7 - packimage and 0 bytes files
Hi all,
I have an xCAT 2.7 cluster where /install resides on an Isilon NFS mount. I
have noticed that after running "packimage" with a standard gzip image, there
are 0 byte binaries in the image file. Everything else in the image seems fine,
and there are no errors shown during the genimage or packimage process. If I
move the /install tree back to local storage, the packimage is fine. The NFS
mount also has plenty of storage available.
I have seen a post about this a few years ago where there wasn't any response
back. Is this a known defect with xCAT/cpio? Has anyone else ran into this
problem before?
Thanks!
