Gernot Hueber <hueber@riic.at> types: > BTW how can I switch to async mode (softupdates or noatime)? noatime is *not* async; it just throws away iformation you may not need. It's an option to the mount command. If you want things to behave just like EXT2, mount the file systems with the async option of the mount command. From the man page: async All I/O to the file system should be done asynchronously. This is a dangerous flag to set, and should not be used unless you are prepared to recreate the file system should your system crash. softupdates is a bit more complicated. You need to use tunefs to enabled (or disable) it on the file system while it's unmounted or mounted read-only. If you've got a sufficiently recent version of newfs, you can enable softupdates when the file system is created. Note that if a file system has soft updates enabled, the async option to the mount command will be ignored. See the various man pages for details. <mike -- Mike Meyer <mwm@mired.org> http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
