Re: Unable to mount / in read - write mode
I can't install FreeBSD 7 from scratch because this is a laptop and the CD drive is dead. Also as this is a laptop I don't have any floopy drive. I have found this thread talking about the same problem: http://unix.derkeiler.com/Mailing-Lists/FreeBSD/current/2006-01/msg00095.html But the /rescue/mount command didn't help me. Does fstab file for a FreeBSD 6.0 and 7.0 are different ? I think yes because before upgrading there were no problem to boot. I also tried to use the mount command in order to get my drive in write mode but it's failed. Is there something to do in order to mount it correctly just one time in order to modify my fstab file ? 2008/11/5 Lowell Gilbert [EMAIL PROTECTED] Popof Popof [EMAIL PROTECTED] writes: The kernel used is a GENERIC one from 6.0. / is mounted but in read-only mode and I can use it in single user mode.

RE: Unable to mount / in read - write mode
On Behalf Of Popof Popof I can't install FreeBSD 7 from scratch because this is a laptop and the CD drive is dead. Also as this is a laptop I don't have any floopy drive. Any chance you have a docking station for that laptop with a NIC that supports PXE? Could you do a network boot and install?

Re: Unable to mount / in read - write mode
My laptop has a bootable NIC but I would like to avoid a network installation. I think that I forget to make the installkernel step. I can say that I'm using kernel 6.0 thanks to the output at the start of boot process. I have another old box with a FreeBSD 6.0 kernel so I'll try tonight to get the mount command from it to an usb key and try to use it with my laptop. I'll also try to provide dmesg if I can use this usb key in write mode. 2008/11/5 Mel [EMAIL PROTECTED] On Wednesday 05 November 2008 14:50:05 Popof Popof wrote: I can't install FreeBSD 7 from scratch because this is a laptop and the CD drive is dead.

Re: Unable to mount / in read - write mode
The kernel used is a GENERIC one from 6.0. / is mounted but in read-only mode and I can use it in single user mode.
