使用 Fake RAID 1 安装 Ubuntu

Question 1

因此，运行 Ubuntu 12.04.1 的安装x64使用备用 CD 的 LTS。

在安装过程中，我选择了手动分区并执行以下操作：
- 使用和格式化 /（根）
- 使用和格式化 SWAP
- 使用和保留 /home 上的数据
- 使用和保留 /data 上的数据

单击“继续”后，出现创建和格式化 SWAP 分区的错误。

我使用 Alt + F2（？）进入终端并按回车键。
我发现只有可见的 RAID 作为没有分区的磁盘。
类似这样的内容：

arek@domek:/var/log/installer$ ls -l /dev/mapper/
lrwxrwxrwx 1 root root 7 Oct  7 20:17 /dev/mapper/pdc_jhjbcaha -> ../dm-0

arek@domek:/var/log/installer$ ls -l /dev/dm*
brw-rw---- 1 root disk 252, 0 Oct  7 20:17 /dev/dm-0

因此我切换到日志控制台 Alt+F3 (?) 并看到如下错误：

如你所见，有 2 个错误

Oct  7 14:02:55 dmraid-activate: ERROR: Cannot retrieve RAID set information for pdc_jhjbcaha

和

Oct  7 14:06:11 partman: mkswap: can't open '/dev/mapper/pdc_jhjbcaha2': No such file or directory

我上网查找并尝试运行命令“dmraid -ay”并得到如下结果：

dmraid -ay
/dev/mapper/pdc_jhjbcaha -> Already activated
/dev/mapper/pdc_jhjbcaha1 -> Successfully activated
/dev/mapper/pdc_jhjbcaha2 -> Successfully activated
/dev/mapper/pdc_jhjbcaha3 -> Successfully activated
/dev/mapper/pdc_jhjbcaha4 -> Successfully activated
/dev/mapper/pdc_jhjbcaha5 -> Successfully activated
/dev/mapper/pdc_jhjbcaha6 -> Successfully activated

然后我使用 Alt+F1 (?) 返回安装程序并单击“返回”以返回分区菜单。我做到了不是改变任何内容只需再次选择“继续”，一切都会顺利进行。

我希望这对某人有帮助。
