blocks|key|5046709|text|这可能有点过分，但我以前喜欢系统映像器做这种工作--尤其是一遍又一遍地部署克隆系统：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5046710|http://wiki.systemimager.org/index.php/Main_页面|offset|length|entityMap|0|LINK|mutability|MUTABLE|url|http://wiki.systemimager.org/index.php/Main_Page^0|0|0|1A|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|N|8|@]|9|@$D|O|E|P|1|Q]]|A|$]]]|F|$G|$5|H|I|J|A|$K|L]]]]

It may be overkill but I used to love systemimager for this kind of work - especially for deploying cloned systems over and over again:

blocks|key|5046629|text|为什么不打破RAID-1和坚持一个新的磁盘？如果您愿意采取停机无论如何，这并不是说，一个不合适的磁盘故障会导致任何可怕的事情发生。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|entityMap^0^^$0|@$1|2|3|4|5|6|7|C|8|@]|9|@]|A|$]]]|B|$]]

Why not break the RAID-1 and stick in one of the new disks? If you're willing to take downtime anyway, it's not as though an inopportune disk failure would cause anything awful to happen.

blocks|key|5046780|text|我做过这件事。使用戴尔的RAID控制器，RAID卷显示为O/S中的单个磁盘，这允许大多数成像软件将其视为单个磁盘。我使用G4L+(可以用于任何O/S，而不仅仅是Linux)映像到附近的FTP服务器或USB磁盘，交换磁盘，重建RAID卷，然后图像返回升级的磁盘。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5046781|如果您想象整个RAID卷，它将为您进行分区。但是，您将拥有与以前完全相同的大小分区，如果要用较大的磁盘替换，则可能会限制分区的大小。您可以在以后添加其他分区，或者在最后一个分区中添加gparted。有远见，将交换和/var作为最后的分区允许这里有更多的灵活性。|5046782|另一种方法是一次映像一个分区。这更繁琐，但允许您在布局新分区方案时具有很大的灵活性--只要每个新分区都是相同大小或大于备份分区！|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|G|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|H|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|I|8|@]|9|@]|A|$]]]|F|$]]

I've done this. With Dell's RAID controller, the RAID volume appears as a single disk to the O/S. This allows most any imaging software to treat it as a single disk. I used G4L (can be used to image any O/S, not just Linux) to image to a nearby FTP server or USB disk, swap out disks, rebuilt RAID volume, and then image back to the upgraded disks.

If you image the entire RAID volume, it will do the partitioning for you. However you will have exactly the same size partitions as before, which may be limiting if you are replacing with larger disks. You can add additional partitions later or bump out the last partition with gparted. With foresight, putting Swap and /var as the last partitions allows some more flexibility here.

The alternative is to image one partition at a time. That is more tedious, but allows you great flexibility in laying out your new partition scheme- as long as each new partition is the same size or larger than the backed-up partition!

blocks|key|5046820|text|为了成功地更新这个问题，我最后使用了上述建议的组合。我选择这个解决方案是因为在我的情况下，一些停机时间是可以的(我更关心的是在数据中心花费的时间更少！)并且想确定它一定会成功。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5046821|移除两个现有驱动器|unordered-list-item|5046822|添加两个新的驱动器和创建新的RAID-1在这些.|5046823|删除一个新的驱动器并替换为旧的一个-你现在有2个退化的RAID-1阵列，都是可访问的。|5046824|引导clonezilla和克隆本地磁盘(g4l看上去无法直接进行本地本地克隆)。|5046825|拆卸旧驱动器并用剩余的新驱动器替换。开始重建数组。启动操作系统。|5046826|..sometime稍后..。用parted/fdisk/regze2fs重新分区|5046827|..。利润：)|5046828|为帮助干杯！|entityMap^0|0|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|T|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|U|8|@]|9|@]|A|$]]|$1|E|3|F|5|D|7|V|8|@]|9|@]|A|$]]|$1|G|3|H|5|D|7|W|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|X|8|@]|9|@]|A|$]]|$1|K|3|L|5|D|7|Y|8|@]|9|@]|A|$]]|$1|M|3|N|5|D|7|Z|8|@]|9|@]|A|$]]|$1|O|3|P|5|6|7|10|8|@]|9|@]|A|$]]|$1|Q|3|R|5|6|7|11|8|@]|9|@]|A|$]]]|S|$]]

To update this question with a successful outcome, I ended up using a combination of the above advice. I picked this solution because some downtime was fine in my situation (I was more concerned with spending less time at the data centre!) and wanted to be definitely sure it'd work.

<ul>
<li>Remove both existing drives</li>
<li>Add both new drives and create new RAID-1 on these.</li>
<li>Remove one of the new drives and replace with one of old - you now have 2 degraded RAID-1 arrays, both accessible.</li>
<li>Boot clonezilla CD and clone local disk-disk (g4l didn't look to be able to do direct local-local clone).</li>
<li>Remove old drive and replace with remaining new drive. Start rebuild of array. Boot up OS.</li>
<li>..sometime later.. repartition with parted/fdisk/resize2fs</li>
</ul>

... profit! :-)

cheers for the help!

Due to a necessary upgrade to larger disks in a Dell server I'd like to image the existing CentOS 5.3 installation and recover this onto new disks.

Because the existing disks are RAID-1 and take up both slots in the machine I can't simultaneously have the new and old disks in at the same time. It's a Dell R300.

I can take server down and I'm comfortable using rescue disks for CentOS, and creating partitions etc, just a question of the data transfer. It'll likely either be to a USB disk or over NFS to another server (NFS probably preferred, as Gigabit so faster).

I presume this is something like running rsync/tar with the right options on the various partitions - anyone done this and can suggest suitable commands to achieve it?

thanks

由于需要升级到Dell服务器中的更大磁盘，我想将现有的CentOS 5.3安装镜像，并将其恢复到新磁盘上。因为现有的磁盘是RAID-1，并且占用了机器上的两个槽，所以我不能同时使用新的和旧的磁盘。这是戴尔的R300。我可以关闭服务器，我很乐意为CentOS使用救援磁盘，创建分区等等，这只是一个数据传输的问题。它可能是USB磁盘上的，也可能是NFS上的另一台服务器(NFS可能是首选的，因为Gigab
