Russell, As you mentioned that 'cpio -H bin' works but 'cpio -H newc/crc' does not work, it should be the issue of cpio that has problem to work with NAS server.
From xCAT point of view, maybe we could try to make the cpio write file to local instead of NFS sever. Could you change the 'cpio -H newc -o | gzip -c - > ../rootimg.gz' to 'cpio -H newc -o | gzip -c - > /tmp/rootimg.gz' or 'cpio -H newc -o > /tmp/rootimg.gz', and take a try that whether /tmp/rotimg.gz could get the correct file size? If yes, we could work around it that cpio output to local first, then copy it from local to remote /install/netboot/...

And please let us know the result of the trying of squashfs or the trying of James's suggestion that using 'cpio -o' replace 'cpio -H newc -o'. Here's the results of my testing: Redirecting errors to cpiolog with archive format as NEWC: No errors recorded, but binaries are still 0 bytes. Example: [root@box3 bin]# pwd /install/netboot/centos6.3/x86_64/compute/rootimg/usr/bin [root@box3 bin]# ll gcc -rwxr-xr-x 2 root root 263824 Jun 22 2012 gcc (Extracted rootimg.gz here) [root@box3 bin]# pwd /install/netboot/centos6.3/x86_64/compute/tmp/usr/bin [root@box3 bin]# ll gcc -rwxr-xr-x 2 root root 0 May 13 10:38 gcc [root@box3 bin]# find . -type f -size 0b ./gcc ./perl ./x86_64-redhat-linux-gcc ./c2ph ./skill ./python ./pgrep ./sudoedit ./python2.6 ./snice ./psed ./sudo ./s2p ./pstruct ./perlbug ./perlthanks ./perl5.10.1 ./pkill Output from /tmp/cpiolog for that file. No errors recorded, and no errors around it. I surfed it and saw nothing out of the ordinary in this log, just a list of files it packed and the final size at the end. ./usr/bin/bzip2 ./usr/bin/factor ./usr/bin/gcc ./usr/bin/mpdsigjob ./usr/bin/yes Changing archive format to BIN (default in copy-out mode for cpio in CentOS 6) in packimage plugin Seems to work fine: [root@box3 bin]# pwd /install/netboot/centos6.3/x86_64/compute/tmp2/usr/bin [root@box3 bin]# ll gcc -rwxr-xr-x 2 root root 263824 May 13 10:55 gcc [root@box3 bin]# find . -type f -size 0b [root@box3 bin]# According to the man page the bin format has a limit of 65,000 inodes though, so if the rootimg is going to need to have a lot of small files in it, it's not practical. I also tried the "crc" format, which according to the man page is NEWC with checksums added, and it showed the same problem - 0 byte files. I have not tried squashfs yet as I am working out the best way of getting the aufs module compiled. I expect it to work fine however. ------------------------------------------------------------------------------ AlienVault Unified Security Management (USM) platform delivers complete security visibility with the essential security capabilities.
