我有带有GPT的2x3TB磁盘,在第一个磁盘(sda4)上使用了2.7TB分区,在第二个磁盘(sdb4)上使用了1TB分区。
原因是最初这两个磁盘都只有1TB,然后我用3TB替换了这两个磁盘。但是,在我使用1x1TB和1x3TB时,我将3TB的其余部分用于一个不同的分区,我现在要删除该分区。
我在Linux上使用了最新的ZFS (0.6.5.7-8-Thezy)。将池大小调整到2.7TB的正确方法是什么?
autoresize当前关闭。这是lsblk和zpool status的当前输出:

但是后来呢?

看上去有点乱。
但简而言之:
autoexpand=on设置在您的zpool上。partprobe或重新启动。zpool online -e zpradix1imain ata-WDC_WD30EZRZ-00WN9B0_WD-WCC4E7CL5U9D-part4和zpool online -e zpradix1imain ata-WDC_WD30EZRX-00D8PB0_WD-WMC4N0E6K1AW-part4 zpool online [-e] pool device...
Brings the specified physical device online.
This command is not applicable to spares or cache devices.
-e Expand the device to use all available space. If the device is part of a mirror or raidz
then all devices must be expanded before the new space will become available to the pool.https://serverfault.com/questions/798907
