我有2x3TB磁盘与GPT和zpool在第一个磁盘(sda4)上使用2.7TB分区,在第二个磁盘(sdb4)上使用1TB.
原因是最初两个磁盘只有1TB,我依次用3TB替换它们.但是在我有1x1TB和1x3TB的时候,我将3TB的剩余部分用于我想要删除的不同分区.
我在Linux上使用最新的ZFS(0.6.5.7-8-wheezy).将池大小调整为2.7TB的正确方法是什么？
autoresize目前已关闭.这是lsblk和zpool状态的当前输出：

作为第一步,我将删除sdb5并将sdb4(通过gdisk)调整为2.7TB并重新扫描分区表(两个磁盘将具有相同的分区布局).
但是之后？
解决方法
这看起来有点混乱.
但简而言之：
>在zpool上设置autoexpand = on.
>将分区大小调整为合适的大小.
>运行partprobe或重启.
>完成后,使用zpool online -e zpradix1imain ata-WDC_WD30EZRZ-00WN9B0_WD-WCC4E7CL5U9D-part4和zpool online -e zpradix1imain ata-WDC_WD30EZRX-00D8PB0_WD-WMC4N0E6K1AW-part4
>重新加载ZFS模块或重新启动.
