在 RAID5 上将磁盘添加到 LVM 后文件系统被破坏了吗？

  • 772

在我的 Openmediavault 存储服务器上添加一点存储容量时出错了。我应该怎么做才能恢复？你能指导我吗？

这是我做的：

1 /dev/md2 raid5 集已创建，进展顺利

2 /dev/md2 pv 创建，进展顺利

3 /dev/md2 pv 包含在卷组 datavg 中运行顺利

4 无法在逻辑卷 datalv 中创建新的文件系统 - 没有可用设备。我现在知道每个 lv 只能有一个 fs，但我尝试时并没有意识到这一点。

5 lvextend 在 datalv 上，进展顺利 - datalv 现在具有全部容量，包括新驱动器

6 仍然无法在 datalv 中创建新的文件系统 — 没有可用的设备。

7 尝试 fsgrow，一下子分配了整个容量 - 这不是我想要的......

8 lvreduce 将 datalv 减少到大约原始容量，进展顺利

9 lvcreate data2lv，进展顺利

10 这次在 data2lv (XFS) 中创建新的文件系统，成功了

重新启动系统后，旧文件系统（数据）无法安装，并且没有新文件系统（XFS）的迹象。

我错误地认为 lv 可以有多个文件系统，所以第 4 步就是问题开始出现的地方。第 5 步也是错的，但也许是可以逆转的。第 7 步是个大错误，因为文件系统不能缩小。其余步骤仍然错误百出，但我该如何修复这个问题？撤消第 8 到第 10 步并只使用一个文件系统？我想我应该在这里问一下，以免把事情搞得更糟。

我将非常感激对此的帮助，

    好的，根据您的元数据，事件的顺序是：

    vgextend datavg /dev/md2
lvextend --extents 100%VG /dev/mapper/datavg-datalv
# guess the datalv filesystem was grown here
lvreduce --extents 30%VG /dev/mapper/datavg-datalv --force
lvcreate --name data2lv --extents 50%VG datavg
# guess the data2lv filesystem was created here
lvreduce --extents 30%VG /dev/mapper/datavg-data2lv --force

    如果是这样，这些lvreduce命令将使两个文件系统都无法访问（设备比文件系统认为的要小）。

    如果data2lv是空的，你可以直接删除它：

    lvremove datavg/data2lv

    （如果data2lv有任何您想要保留的数据，您必须先恢复其原始大小，然后将其传输到其他地方。）

    恢复原始大小，因为datavg/datalv，之后data2lv已被删除。

    根据元数据，这是datalv当前布局：

    […]
segment_count = 2

segment1 {
    start_extent = 0
    extent_count = 2146093  # 8.1867 Terabytes

    type = "striped"
    stripe_count = 1    # linear

    stripes = [
        "pv0", 0
    ]
}
segment2 {
    start_extent = 2146093
    extent_count = 643652   # 2.45534 Terabytes

    type = "striped"
    stripe_count = 1    # linear

    stripes = [
        "pv1", 0
    ]
}
[…]

    这是你想要实现的改变：

    […]
segment2 {
    start_extent = 2146093
    extent_count = 7153054  # 27.2867 Terabytes

    type = "striped"
    stripe_count = 1    # linear

    stripes = [
        "pv1", 0
    ]
}
[…]

    因此需要添加的是pv1:643652-7153053。

    其中pv0，pv1指的是这些物理卷：

    pv0 {
    id = "I2RWJZ-s9Rv-kZlC-jSTG-BFII-ZeK8-0JS1rL"
    device = "/dev/md0" # Hint only
    […]
    pe_count = 2146093  # 8.1867 Terabytes
}

pv1 {
    id = "WldN1d-SmhW-u9cB-PDOD-W7fE-j7gP-56Wc9d"
    device = "/dev/md2" # Hint only
    […]
    pe_count = 7153054  # 27.2867 Terabytes
}

    因此你可以用这个命令试试运气：

    lvextend datavg/datalv /dev/disk/by-id/lvm-pv-uuid-WldN1d-SmhW-u9cB-PDOD-W7fE-j7gP-56Wc9d:643652-7153053

    然后在元数据中验证片段。

    这实际上是最简单的情况。没有发生段碎片或重新排序。这只是同一 PV 内的线性扩展。因此，lvextend -l+100%FREE datavg/datalv在这里简单地运行也应该有效。

    现在，您可以恢复您的datalv文件系统吗？

    视情况而定。从技术上讲，您在 中创建新的文件系统data2lv并覆盖了 中仍属于该文件系统的范围，从而破坏了它datalv。

    但是，如果在增长后没有文件或元数据写入该区域，它可能会幸存下来。运气好的话，mount此时就可以正常工作。

    如果您仍然想缩小它，则必须使用 、 或让 LVM 使用 来正确执行e2fsck此resize2fs操作lvreduce --fs resize（对于旧版本的 LVM）。除非您确实确定文件系统是安全的，否则lvreduce --resizefs请不要使用--force或选项……ignore
