While iflag=count_bytes combined with bs > 1 allows for more efficient operation, it is a feature of GNU dd, and not present on other implementations such as BSD. Sticking to just POSIX features makes things more portable. Signed-off-by: Eric Blake <eblake@redhat.com> --- docs/nbdkit-loop.pod...

Hello, I have found, that ocfs2 is very slow when doing I/O operation without cache. See a simple test: ng-vvv1:~# dd if=/data/verejna/dd-1G bs=1k | dd of=/dev/null 1048576+0 records in 1048576+0 records out 1073741824 bytes (1.1 GB) copied, 395.183 s, 2.7 MB/s 2097152+0 records in 2097152+0 records out 1073741824 bytes (1.1 GB) copied, 395.184 s, 2.7 MB/s The underlying block device is quite

Hi r-help, I have some troubles reading fortran binary file(from mm5) in R. Here is what I have done. 1. Use a fortran subroutine to read this file in R. The subroutine is as the following. subroutine freadmm5(filenamet,out2d) integer iflag,var1,miy,mjx,mkz,mt,z,t character*4 crdt,corder character*24 chrdate character*9 cname,var character*25 cunit,uunit,vunit,wunit character*80 filename real out2d(157,109),out3d(157,109,24) OPEN (11,FILE=filename,FORM='UNFORMATTED') 10 READ(11) IFL...

Dear List, I checked the function "generate_files", which might be simply stand for generator, but didn't find where triggers the file transfer. As receiver will use "read_ndx_and_attrs" to read iflags to judge if it's need to be transfered? If I'm wrong, please correct me. Can anyone help to point it out? Thanks. -- Daniel Li

Hi All, I am running on CentOS Released 6.1 final. Been using and running Linux KVM quite well for quite some time, something goes wrong after I perform yum upgrade. I created new VM yesterday without any problem, same exact installation procedure, installed FreeBSD 8.2. I tried to create a new VM today after yum upgrade, it's able to detect the hard disk, when I start commit FreeBSD 8.2
