Package: coreutils Version: 5.2.1-2.1 Severity: normal Filling this bug as normal instead of wishlist because the lack of O_DIRECT in dd during big io takss causes the kernel to pratically discard all useful cached data and inodes, thus degrading system performance a great deal for no good reason.
Coreutils dd does not yet support opening input and output files in O_DIRECT mode, which would be extremely helpful for a great number of operations dd is used for, which are almost always done only once. The RAW devices are scheduled for removal from Linux in December 2005. They are currently the only possible way to work around dd's lack of O_DIRECT support. The use of O_DIRECT should be user-selectable, of course. -- System Information: Debian Release: testing/unstable APT prefers unstable APT policy: (990, 'unstable'), (1, 'experimental') Architecture: i386 (i686) Shell: /bin/sh linked to /bin/bash Kernel: Linux 2.6.13.4-debian1+libata+bluesmoke+imq+lm85 Locale: LANG=pt_BR.ISO-8859-1, LC_CTYPE=pt_BR.ISO-8859-1 (charmap=ISO-8859-1) Versions of packages coreutils depends on: ii libacl1 2.2.29-1.0.1 Access control list shared library ii libc6 2.3.5-6 GNU C Library: Shared libraries an coreutils recommends no packages. -- no debconf information -- "One disk to rule them all, One disk to find them.
