If possible could you try to do the following change when you could
recreate the issue on NetApp or Isilon.
Replace the '|cpio -H newc -o |' part with '|cpio -H newc -o
--verbose 2>/tmp/cpiolog |' and to see what we could get in the
'/tmp/cpiolog' when issue happens.
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.
