coLinuxでのディスクイメージ容量拡張

Linux coLinux

coLinuxのサイトから入手できるDebian lennyイメージは2GBしかないので、8GBに拡張しました。

まずfsutilでイメージファイルを用意します。

> fsutil file createnew lenny.8gb 8589934592
File C:\Program Files\coLinux\lenny.8gb is created

debian-lenny.confにcobd3="lenny.8gb"を加えてcoLinuxを起動し、mkfsでファイルシステムを作成します

colinux:~# mkfs.ext3 /dev/cobd3
mke2fs 1.41.3 (12-Oct-2008)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)

Writing inode tables: done
Creating journal (32768 blocks): done
Writing superblocks and filesystem accounting information: done

This filesystem will be automatically checked every 28 mounts or
180 days, whichever comes first.  Use tune2fs -c or -i to override.

ddでデバイスの中身をコピーし、resize2fsで拡張します。

colinux:/# dd if=/dev/cobd0 of=/dev/cobd3

4194304+0 records out
2147483648 bytes (2.1 GB) copied, 340.82 s, 6.3 MB/s
colinux:/# e2fsck -f /dev/cobd3

Resizing the filesystem on /dev/cobd3 to 2097152 (4k) blocks.

cobd3をcobd0と入れ替えて完了です。
