Hi,
I prepared on a secondary internal hard drive a skeleton FreeBSD 8.1-RELEASE (GENERIC) system, that features the complete setup for my purpose, but does not contain any data. I verified that the ssytem is working according to my needs.
In a second step I prepared an USB memory stick with being bootable with the more or less standard UFS slices:
Then I transferred said skeleton system to the USB stick, and I changed /etc/fstab at the USB stick to have the proposed device names /dev/da0s1a-f:
If I reboot the computer with this USB stick plugged-in, the computer starts from it, but it hangs requesting a manual mountroot.
So the system is throwing a ROOT MOUNT ERROR when "Trying to mount root from ufs:/dev/da0s1a". However, when I enter exactly that device node at the mountroot> prompt, the system happily boots from the USB stick, and I verified that everything is running as expected.
I am researching now two days on this issue and I have still no idea how I can get the system boot from the USB stick in one shot, i.e. without needing to enter something at the mountroot> prompt.
I would be grateful for any insights on what is going on here.
Many thanks in advance and best regards
Rolf
I prepared on a secondary internal hard drive a skeleton FreeBSD 8.1-RELEASE (GENERIC) system, that features the complete setup for my purpose, but does not contain any data. I verified that the ssytem is working according to my needs.
In a second step I prepared an USB memory stick with being bootable with the more or less standard UFS slices:
Code:
server:~ root# gpart show da0
=> 63 7831467 da0 MBR (3.7G)
63 7831467 1 freebsd [active] (3.7G)
server:~ root# gpart show da0s1
=> 0 7831467 da0s1 BSD (3.7G)
0 393216 1 freebsd-ufs (192M)
393216 1572864 2 freebsd-swap (768M)
1966080 196608 4 freebsd-ufs (96M)
2162688 196608 5 freebsd-ufs (96M)
2359296 5472171 6 freebsd-ufs (2.6G)
Then I transferred said skeleton system to the USB stick, and I changed /etc/fstab at the USB stick to have the proposed device names /dev/da0s1a-f:
Code:
# Device Mountpoint FStype Options Dump Pass#
/dev/da0s1b none swap sw 0 0
/dev/da0s1a / ufs rw 1 1
/dev/da0s1e /tmp ufs rw 1 1
/dev/da0s1f /usr ufs rw 1 1
/dev/da0s1d /var ufs rw 1 1
/dev/acd0 /cdrom cd9660 ro,noauto 0 0
If I reboot the computer with this USB stick plugged-in, the computer starts from it, but it hangs requesting a manual mountroot.
Code:
