It only seems ok in 4.3 *if you ignore the warning from newfs*. I repeat: running newfs on a block device is not good. Use the raw device. 4.4 enforces that, but if you are running newfs on an older system, this holds too. Background: writing to a block device is not order-preserving: newfs writes multiple times to the same block. So you can end up with a filesystem that is inconsitent from the beginning. -Otto
Re: OpenBSD 4.4 - fdisk issue
Hi I just try to install OpenBSD 4.4 on a serveur (HP DL120 G5) to test the functionality of the raid (seens it works again .). I configure the first disk without any issue, and then try following commands: disklabel wd0 disklabel.wd1 fdisk -i wd1 disklabel -R -r wd1 disklabel.wd1 newfs /dev/wd1a Error: newfs: /dev/wd1a: block device Same message when I try a mount. Not a problem I continue and made a new installation on wd1 (with the CD) Then I build my raid0 configuration (by compiling the kernel) and try to create the new disk: fdisk -i raid0 disklabel -E -raid0 newfs /dev/raid0a = same error by newfs and mount What do I wrong ? Regards Thanks for all the answer. The answer should be disklabel wd0 disklabel.wd1 fdisk -i wd1 disklabel -R -r wd1 disklabel.wd1 newfs /dev/rwd1a instead of newfs /dev/wd1a mount /dev/wd1a /mnt And fdisk -i raid0 disklabel -E -raid0 newfs /dev/rraid0a instead of newfs /dev/raid0a mount /dev/raid0a /mnt

Use the raw device. 4.4 enforces that, but if you are running newfs on an older system, this holds too. Ok, thanks, and sorry if I seem to have suggested otherwise. The man page says that if I use a relative path then newfs will do the right thing (use the corresponding raw device), and that's the form of the command in Section 14.3 of the FAQ. What I read in the FAQ (and in the EXAMPLES sections of man pages) I am inclined to take as recommended usage. Is that the case here, too? cheers, (and thanks for the background info) -wb

OpenBSD 4.4 - fdisk issue
Hi I just try to install OpenBSD 4.4 on a serveur (HP DL120 G5) to test the functionality of the raid (seens it works again .). I configure the first disk without any issue, and then try following commands: disklabel wd0 disklabel.wd1 fdisk -i wd1 disklabel -R -r wd1 disklabel.wd1 newfs /dev/wd1a Error: newfs: /dev/wd1a: block device Same message when I try a mount. Not a problem I continue and made a new installation on wd1 (with the CD) Then I build my raid0 configuration (by compiling the kernel) and try to create the new disk: fdisk -i raid0 disklabel -E -raid0 newfs /dev/raid0a = same error by newfs and mount What do I wrong ? Regards

Use the raw device (/dev/rwd1a). Running newfs on a block device (/dev/wd1a) can lead to subtle and hard to diagnose problems. That's why it has been disabled in 4.4. -Otto
