标题: XenSystem重装系统后挂载硬盘失败
晕了，XenSystem的VPS，重装系统后系统未使用空间挂载不上去了，按照教程搞不定，好像要把原先的物理卷删除才行，不会做了。

俺上次一VPS，重装系统直接挂掉了

作者: befree 时间: 2011-1-2 10:23
晕，都没有解决的办法吗？

楼主,如果你重装前已经挂载成功,重装后只需要动态扩容一下就可以了,相关教程请参阅我博客,手机上的,没办法发你。

闲得无聊就不要乱折腾lvm，我一般是合硬盘采用

作者: l4steleven 时间: 2011-1-2 11:20
如果你之前操作错误,可以删除分区,重新分区挂载

作者: 不夠慘 时间: 2011-1-2 11:37

直接动态扩容就可以了，不用作其它的了

resize2fs /dev/VolGroup00/LogVol00

复制代码

resize2fs /dev/VolGroup00/LogVol00

直接动态扩容已经试过了，还是挂载不上去

# resize2fs /dev/VolGroup00/LogVol00
resize2fs 1.39 (29-May-2006)
The filesystem is already 1531904 blocks long. Nothing to do!
