Hi Andrey,
Why would you want a block size in GB? I don't know what the
actual limit for dd itself is, although it does seem to be exactly 2GiB.
regards,
Stephen.

Hi Stephen,
thank you for your reply.
======
[root@pcfarm-10 ~]# rpm -qa --queryformat "%{NAME}-%{VERSION}.%{ARCH}\n" |
grep coreutils
policycoreutils-1.33.12.x86_64
policycoreutils-newrole-1.33.12.x86_64
coreutils-5.97.x86_64
policycoreutils-gui-1.33.12.x86_64

And obviously
================
[root@pcfarm-10 ~]# arch
x86_64
===============
The result is prety same as I shown earlier.
And the same I see at CERN
=======================
[lxplus427] /afs/cern.ch/user/s/shevel > dd if=/dev/zero of=/tmp/testx64
bs=3GB count=1
0+1 records in
0+1 records out
2147479552 bytes (2.1 GB) copied, 5.91242 seconds, 363 MB/s

coreutils-5.97.x86_64
policycoreutils-gui-1.33.12.x86_64
===========================
As far as I understand the main question is "is there 64 bit dd version which
can operate more then 2GB value for BS in SL anyway?"
Any answer (yes or no) is good to know.
Many thanks,
Andrey

Subject: Re: coreutils for 64 bit
Exactly.... if you type "man rpm" it will show you how you get it to print
the arch string (usually i686 or x86_64). Since you seem unabel to read a
man page what you want to type is;
rpm -qa --queryformat "%{NAME}-%{VERSION}.%{ARCH}\n" | grep coreutils
(or miss out the VERSION if you want to see somethign similar to yum)

Hi Stephen,
thanks for the reply.
I am not sure that I do understand you (sorry for my stupidity).
I have
=======================================
[root@pcfarm-10 ~]# yum list | grep coreutil
Failed to set locale, defaulting to C
coreutils.x86_64 5.97-34.el5 installed
policycoreutils.x86_64 1.33.12-14.8.el5 installed
policycoreutils-gui.x86_64 1.33.12-14.8.el5 installed
policycoreutils-newrole.x86_64 1.33.12-14.8.el5 installed
[root@pcfarm-10 ~]# rpm -q --file /bin/dd
coreutils-5.97-34.el5
=============================================
Presumably all packages are appropriate (they have suffix x86_64) as
shown
by yum.
At the same time rpm does show packages without above suffixes
=========================
[root@pcfarm-10 ~]# rpm -qa | grep coreutil
policycoreutils-1.33.12-14.8.el5
policycoreutils-newrole-1.33.12-14.8.el5
coreutils-5.97-34.el5
policycoreutils-gui-1.33.12-14.8.el5
=========================
