黑裙 raid1 如何扩容

  •  
  •   Kerwin1202 · 62 天前 · 1093 次点击
    这是一个创建于 62 天前的主题,其中的信息可能已经有所发展或是发生改变。

    用的 vm 弄得虚拟机 装的黑裙,当初装的时候,新建了两个虚拟硬盘 150G, 组了个 raid1, 但是现在发现磁盘有点不够,给两个硬盘都扩容到 500G , Nas 里看到的存储池两个硬盘确实是 500G 但是可用还是 150G,

    用网上说的物理硬盘的形式,插拔形式同步替换了好像也不行。

    网上说的比较多的是 grow 但是依旧是 150 G 而不是 500

    # mdadm --grow --size=max /dev/md2
    mdadm: component size of /dev/md2 unchanged at 152464384K
    
    

    然后

    # resize2fs  /dev/md2
    resize2fs 1.42.6 (21-Sep-2012)
    resize2fs: Device or resource busy while trying to open /dev/md2
    Couldn't find valid filesystem superblock.
    

    似乎都不行. 求大佬解答下。

    还是只能采用新的两个硬盘组个新的 raid1,把数据同步到这个新的存储池,删掉旧的。

    大哥你只扩展了磁盘大小, 组成 ayyay 的两个分区大小没有改啊
    修改 /dev/sdd 和 /dev/sde 的分区表, 把分区 3 改成最大, 再扩展 raid
