97: - During the partitioning process, do not delete or format the
1.7 wiki 98: first MSDOS (FAT) partition, as this is what your firmware by default boots from
99: (unless you have prepared a boot partition on other media).
1.8 wiki 100: - For accident-free operation of resize_ffs, the filesystem it is supposed to grow needs to be either not mounted or at least not mounted for writing.
101: To do that for a root filesystem, reboot to single user, and at the prompt to enter the pathname of shell, press
1.4 mspo 102: return for the default (/bin/sh).
103: - At the # prompt, type
104:
105: "disklabel -i ld0" and press return.
106: - At the partition> prompt type "A" and press return.
107:
108: Adjust disklabel sector from 4194304 to 62333952 [n]?
109: Type "y" and press return.
110: - partition> prompt type "a" and press return.
111:
112: Filesystem type prompt, press return to use the current value (4.2BSD).
113: Start offset prompt, press return to use the current value.
114: Partition size prompt, type "$" and press return to grow the
115: partition to use all available free space.
116: - partition> prompt type "W" to save the changes to the disklabel.
117:
118: Confirm this choice by typing "y" at the Label disk prompt.
119: Type "Q" and press return to quit disklabel.
120: - At the # prompt (shell), type
121:
122: fsck -fy /dev/rld0a
123: resize_ffs -y /dev/rld0a
124: - This may take a few minutes, be patient!

128: reboot
