自定义rpm pkg安装时间很长，最终导致cpio错误

Question

The rpm package which i created takes long time to install. It contains only database file of Berkely db format and size 2.2GB.

Below is my RPM spec

#AutoReq: no
AutoReqProv: no
%define PYTHON /usr/bin/python
%define RPM_BUILD_DIR %{_topdir}/BUILD
%define RPM_BUILD_ROOT %{_topdir}/tmp
%global __os_install_post %(echo '%{__os_install_post}' | sed -e 's!/usr/lib[^[:space:]]*/brp-python-bytecompile[[:space:]].*$!!g')

%define _source_payload w0.gzdio
%define _binary_payload w0.gzdio

- Create prefixcat db as a seperate rpm

rpm ivh prefixcat-1.1.100.x86_64.rpm, takes almost 15mins to install.

Also the above command causes this error

error: unpacking of archive failed on file /data/db/wbrs/factory/db/prefixcat_db;59818e12: cpio: read failed - Bad file descriptor

Any help on how to compress the size and install faster?

Fyi:- i am building this rpm on CentOS7 and installing on windriver 8. RPM version is same across both OS.

If the target architecture is 32-bit you might be running into a 2GB file size limit. What is the target architecture and root filesystem type?

EDIT: Since you are using a 64-bit kernel a 2GB limit is far less likely.

Have you verified (with sha256sum or similar) that the .rpm file on the remote system matches the file on your development system?
